FIG. 1 is a flow chart illustrating a method of controlling an offshore wind power system in accordance with an embodiment of the disclosure.
Referring to fig. 1, at step S110, at least one of a remote input/output (I/O) module, a typhoon resistant controller, a beidou communication system, and an anemometer in an offshore wind power system is powered by a storage battery.
According to the embodiment of the disclosure, the unit controller is used for controlling the wind generating unit, the typhoon resistant controller is used for controlling typhoon resistant operation of the offshore wind power system, the Beidou communication system is used for transmitting and exchanging Beidou satellite terminal and land centralized control center data, and the anemometer is used for detecting current wind speed in real time. Thus, when the offshore wind power system encounters a typhoon, at least one of a remote input/output module, an anti-typhoon controller, a Beidou communication system and an anemometer in the offshore wind power system may be powered by the storage battery so as to cope with the influence of the typhoon.
In one embodiment, step S110 may specifically include powering a remote input/output module of a wind turbine of the offshore wind turbine via a battery of the wind turbine of the offshore wind turbine, and powering at least one of an anti-typhoon controller, a Beidou communication system, and an anemometer of the offshore wind turbine via a battery of a diesel generator of the offshore wind turbine.
According to the embodiment of the disclosure, the diesel generator set of the offshore wind power system can provide a main power supply for the wind generator set when a power grid is powered down or is not powered. The storage battery of the wind power generator set of the offshore wind power system can be called a continuous backup battery set, which can continuously provide 24V control power for the system when the diesel generator is not in operation. The battery of the diesel generator of the offshore wind power system can be used for supplying power to at least one of the typhoon resistant controller, the Beidou communication system and the anemometer of the offshore wind power system when the power grid is powered down or in the absence of power. Thus, in embodiments of the present disclosure, the use of a battery of a wind power generator set and a battery of a diesel generator to power different components, respectively, rather than using a single battery to power all components, may maximize the operating time of each component and improve overall power efficiency.
In step S120, one of a data acquisition and monitoring System (SCADA) system, a beidou terminal and an anemometer is selected based on availability of communication links of the SCADA system and the beidou communication system with the remote input/output module.
According to the embodiment of the disclosure, the SCADA is an automatic monitoring system based on a computer, can monitor and control operation equipment on site and is widely applied to a wind power generation system so as to realize various functions of data acquisition, equipment control, measurement, parameter adjustment, various signal alarms and the like for the wind power generation system. When a typhoon is encountered, the control method of the offshore wind power system according to the embodiment of the present disclosure may first check the availability of the communication links of the SCADA system and the beidou communication system with the remote input/output module before performing the typhoon resistant operation, so that when one of the communication links of the SCADA system and the remote input/output module and the beidou communication system is unavailable, communication is not performed through the corresponding communication link, and thus, the communication efficiency of the typhoon resistant operation may be improved, and unnecessary time loss may be avoided.
In step S130, an anti-typhoon strategy is performed based on a selected one of the SCADA system, the beidou terminal, and the anemometer.
Based on this, when the communication link of the SCADA system with the remote input/output module is available, or when the communication link of the SCADA system with the remote input/output module is not available and the communication link of the beidou communication system with the remote input/output module is also not available, a selected one of the SCADA system, the beidou terminal, and the anemometer may be selected, and the typhoon resistance strategy is performed based on the selected one of the SCADA system, the beidou terminal, and the anemometer. According to the control method of the offshore wind power system, one of the SCADA system, the Beidou terminal and the anemometer can be selected based on the availability of communication links of the SCADA system and the Beidou communication system with the remote input/output module, and the typhoon resistant strategy is executed based on the selected one of the SCADA system, the Beidou terminal and the anemometer, so that typhoon resistant operation can be reliably executed.
Hereinafter, a control method of the offshore wind power system in the case where the offshore wind power system is in a construction stage and an operation stage will be described with reference to fig. 2 and 3, respectively.
FIG. 2 is a flowchart illustrating a method of controlling an offshore wind turbine system with the offshore wind turbine system in a build phase, in accordance with an embodiment of the disclosure.
Referring to fig. 2, in case that the offshore wind power system is in a construction stage, step S110 in fig. 1 may correspond to step S210 in fig. 2. In step S210, when no typhoon warning is received, at least one of a remote input/output module, an anti-typhoon controller, a Beidou communication system and an anemometer in the offshore wind power system is powered through a storage battery.
According to embodiments of the present disclosure, the offshore wind system being in a construction phase may represent the offshore wind system being in a hoisting phase. At this point, the entire offshore wind power system is off-grid and power delivery via the collector sea cable and communication via the land control center and/or SCADA has not been enabled. Thus, according to an embodiment of the present disclosure, when in a typhoon season, since the offshore wind power system may frequently encounter typhoons, the offshore wind power system may perform an anti-typhoon operation when typhoon warning is received, or may supply at least one of a remote input/output module, an anti-typhoon controller, a Beidou communication system, and an anemometer in the offshore wind power system through a battery when typhoon warning is not received, thereby preparing for the arrival of typhoons.
In case the offshore wind power system is in a construction phase, step S120 in fig. 1 may correspond to step S220 in fig. 2. In step S220, one of the beidou terminal and the anemometer is selected based only on the availability of a communication link of the beidou communication system with the remote input/output module.
As mentioned above, the offshore wind power system being in a build phase may mean that power transfer via the collector sea cable and communication via the land control center and/or SCADA has not been enabled. Therefore, in the case that the offshore wind power system is in the construction stage as shown in fig. 2, it may not be necessary to judge the availability of the communication link of the SCADA system and the remote input/output module as in step S120 in fig. 1, but only to judge the availability of the communication link of the beidou communication system and the remote input/output module, and since the SCADA system needs to operate in cooperation with the remote input/output module, it may not be necessary to select the SCADA system but only one of the beidou terminal and the anemometer in the construction stage of the offshore wind power system in which the SCADA system and/or the remote input/output module are not available, thereby improving the operation efficiency.
In case the offshore wind power system is in a construction phase, step S130 in fig. 1 may correspond to step S230 in fig. 2. In step S230, a typhoon resistance strategy is performed by communicating with a typhoon resistance controller based on a selected one of the beidou terminal and the anemometer.
Based on this, in the case where the offshore wind power system is in a construction phase, when a communication link of the Beidou communication system with the remote input/output module is available or when a communication link of the Beidou communication system with the remote input/output module is not available, a selected one of the Beidou terminal and the anemometer may be selected, and the typhoon resistance strategy is performed based on the selected one of the Beidou terminal and the anemometer. According to the control method of the offshore wind power system, one of the Beidou terminal and the anemometer can be selected based on the availability of the communication link of the Beidou communication system and the remote input/output module, and the typhoon resistance strategy is executed based on the selected one of the Beidou terminal and the anemometer, so that typhoon resistance of the offshore wind power system during a construction stage can be realized.
FIG. 3 is a flowchart illustrating a method of controlling an offshore wind system with the offshore wind system in an operational phase in accordance with an embodiment of the disclosure.
According to the embodiment of the disclosure, compared with the construction stage of the offshore wind power system, the offshore wind power system in the operation stage can represent that the offshore wind power system is constructed and can smoothly perform the power generation task. At this point, the entire offshore wind power system has normally completed access to the grid and the power transfer via the collector sea cable and communication via the land control center and/or SCADA has been installed. Thus, referring to FIG. 3, with the offshore wind system in an operational phase, step S110 in FIG. 1 may correspond to the combination of step S310 and step S320 in FIG. 3.
In step S310, when a typhoon warning is received, it is determined whether the power grid is powered down.
According to the embodiment of the disclosure, because typhoons are frequently encountered in typhoons, power failure is likely to occur due to the influence of previous typhoons or other factors on both the offshore wind power system end and the land end of the power grid. Thus, it may be determined first whether the grid is powered down before performing other operations, thereby more effectively coping with typhoons. For example, when the power grid is not powered down, power may be transmitted directly through the power grid to various components or modules of the offshore wind power system, and when the power grid is powered down, step S320 may be performed.
In step S320, in response to determining that the grid is powered down, it is checked whether a communication link between the SCADA system and the beidou communication system and the remote input/output module is available and at least one of the remote input/output module, the typhoon resistant controller, the beidou communication system and the anemometer in the offshore wind power system is powered by a battery.
According to embodiments of the present disclosure, since typhoons are frequently encountered in typhoons, both SCADA systems and beidou communication systems may fail under the influence of previous typhoons or other factors. Therefore, in the case that the offshore wind power system is in an operational stage, when a typhoon is encountered, the control method of the offshore wind power system according to the embodiment of the present disclosure may first check the availability of the communication links of the SCADA system and the beidou communication system with the remote input/output module before performing the typhoon resistant operation, so that when one of the communication links of the SCADA system and the remote input/output module and the beidou communication system is unavailable, communication is not performed through the corresponding communication link, and thus, the communication efficiency of the typhoon resistant operation may be improved, avoiding unnecessary time loss.
In one embodiment, in response to determining that the power grid is down, it may also be determined whether the diesel generator is operating. For example, in response to determining that the diesel generator is operating, the diesel generator may be used to charge a battery of a wind turbine generator set of the offshore wind power system and a battery of the diesel generator. Therefore, the battery of the wind generating set and the battery of the diesel generator can be kept in an electric state, thereby better supporting typhoon-resistant operation. In addition, in the case that the offshore wind power system further comprises a photovoltaic power generation system, in response to determining that the diesel generator is not operating, the photovoltaic power generation system may be switched in, and the photovoltaic power generation system is used to charge a storage battery of a wind power generation set of the offshore wind power system and a storage battery of the diesel generator of the offshore wind power system, and in response to determining that the power grid is not powered down or determining that the diesel generator is operating, the photovoltaic power generation system is switched out. Therefore, when the offshore power generation unit is off-grid for a long time, the off-grid standby time of the diesel generator can be prolonged, and the diesel reserve of the diesel generator can be reduced.
In case the offshore wind power system is in an operational phase, step S120 in fig. 1 may correspond to a combination of step S330 and step S340 in fig. 3.
In step S330, the SCADA system is selected to communicate with the typhoon resistant controller when a communication link between the SCADA system and the remote input/output module is available. That is, in this case, the SCADA system may be selected to wake up the fan controller to achieve typhoon resistant operation.
For example, when a communication link between the SCADA system and the remote input/output module is available, an anti-typhoon command provided by the anti-typhoon controller can be transmitted to the remote input/output (I/O) module of the unit control system through a ring network switch of the unit control system by the SCADA system as a central control, a relay of the fan controller is controlled to be closed by the remote I/O module, a 24V battery of the wind generating set provides an input 24V Direct Current (DC) power supply to the fan controller, the fan controller is awakened, the diesel engine is started by the fan controller, and a breaker of the diesel engine is controlled to be closed, so that the anti-typhoon command provided by the anti-typhoon controller can finally realize anti-typhoon operation of the wind generating set through the SCADA system and the fan controller.
In step S340, when the communication link of the SCADA system with the remote input/output module is not available, one of the beidou terminal and the anemometer is selected to communicate with the typhoon resistant controller based only on the availability of the beidou communication system.
Step S340 in fig. 3 may be similar to step S220 in fig. 2 according to an embodiment of the present disclosure. That is, the operation "select one of the beidou terminal and the anemometer based only on the availability of the beidou communication system" in step S340 in fig. 3 may be the same as step S220 in fig. 2. In one embodiment, the operation in step S340 in fig. 3 of selecting one of the beidou terminal and the anemometer based only on the availability of the beidou communication system and step S220 in fig. 2 may include step S341 (not shown) and step S342 (not shown).
In step S341, when a communication link between the beidou communication system and the remote input/output module is available, a beidou terminal is selected. That is, in this case, the Beidou terminal may be selected to wake up the fan controller so as to achieve typhoon resistant operation.
For example, the Beidou command machine of the Beidou communication system can send a remote control instruction to the Beidou server (for example, a Beidou satellite), the Beidou server can send a starting instruction to the Beidou terminal after receiving the remote control instruction, and the Beidou terminal can feed back a successful receiving instruction to the Beidou command machine through the Beidou server after receiving the starting instruction and can establish communication with the anti-station controller. The anti-station controller can establish communication with a ring network switch and a remote I/O module of the unit control system, and the remote I/O module controls the relay of the fan controller to be closed so as to wake up the fan controller. The fan controller can start the diesel engine and control the breaker of the diesel engine to be switched on, so that the typhoon-resistant command provided by the typhoon-resistant controller can finally realize typhoon-resistant operation of the wind driven generator through the Beidou communication system and the fan controller.
In step S342, an anemometer is selected when a communication link of the beidou communication system with the remote input/output module is not available. That is, in this case, the anemometer may be selected to wake up the fan controller to achieve typhoon resistant operation.
For example, the anemometer may detect the current wind speed in real time and feed it back to the anti-stage controller. When the wind speed reaches the typhoon-resistant triggering condition, the typhoon-resistant controller can be communicated with a remote I/O module of the unit control system, so that the remote I/O module controls the relay, a 24V storage battery of the wind generating set provides an input 24V DC power supply for the fan controller, and the fan controller is awakened. The fan controller starts the diesel engine and controls the breaker of the diesel engine to be switched on, so that the typhoon-resistant command provided by the typhoon-resistant controller can finally realize typhoon-resistant operation of the wind driven generator through the anemometer and the fan controller.
Thus, the offshore wind turbine according to the embodiment of the present disclosure can reliably perform the typhoon-resistant operation, regardless of the construction stage or the operation stage of the offshore wind turbine.
FIG. 4 is a block diagram illustrating an offshore wind power system in accordance with an embodiment of the present disclosure.
Referring to FIG. 4, the offshore wind power system 100 may include a power module 110, a selection module 120, a communication module 130, and an execution module 140.
The power module 110 may be configured to power at least one of a remote input/output module, a typhoon resistant controller, a Beidou communication system, and an anemometer in an offshore wind power system through a battery. Thus, when the offshore wind power system encounters a typhoon, at least one of a remote input/output module, an anti-typhoon controller, a Beidou communication system and an anemometer in the offshore wind power system may be powered by the storage battery so as to cope with the influence of the typhoon.
In one embodiment, the power module 110 may be specifically configured to power the remote input/output module of the wind turbine of the offshore wind turbine via a battery of the wind turbine of the offshore wind turbine and to power at least one of the anti-typhoon controller, the Beidou communication system, and the anemometer of the offshore wind turbine via a battery of a diesel generator of the offshore wind turbine. Thus, in embodiments of the present disclosure, the use of a battery of a wind power generator set and a battery of a diesel generator to power different components, respectively, rather than using a single battery to power all components, may maximize the operating time of each component and improve overall power efficiency.
The selection module 120 may be configured to select one of the SCADA system, the beidou terminal and the anemometer based on availability of the SCADA system and the beidou communication system. When a typhoon is encountered, the control method of the offshore wind power system according to the embodiment of the present disclosure may first check the availability of the communication links of the SCADA system and the beidou communication system with the remote input/output module before performing the typhoon resistant operation, so that when one of the communication links of the SCADA system and the remote input/output module and the beidou communication system is unavailable, communication is not performed through the corresponding communication link, and thus, the communication efficiency of the typhoon resistant operation may be improved, and unnecessary time loss may be avoided.
The communication module 130 may be configured to communicate with the typhoon resistant controller based on a selected one of the SCADA system, the beidou terminal, and the anemometer. The execution module 140 may be configured to execute the typhoon resistant strategy through the typhoon resistant controller. According to the control method of the offshore wind power system, one of the SCADA system, the Beidou terminal and the anemometer can be selected based on the availability of communication links of the SCADA system and the Beidou communication system with the remote input/output module, and the typhoon resistant strategy is executed based on the selected one of the SCADA system, the Beidou terminal and the anemometer, so that typhoon resistant operation can be reliably executed.
In the case that the offshore wind power system is in a construction stage, the power supply module 110 may be configured to supply at least one of a remote input/output module, an anti-typhoon controller, a Beidou communication system, and an anemometer in the offshore wind power system through the storage battery when the typhoon warning is not received. Thus, according to an embodiment of the present disclosure, when in a typhoon season, since the offshore wind power system may frequently encounter typhoons, the offshore wind power system may perform an anti-typhoon operation when typhoon warning is received, or may supply at least one of a remote input/output module, an anti-typhoon controller, a Beidou communication system, and an anemometer in the offshore wind power system through a battery when typhoon warning is not received, thereby preparing for the arrival of typhoons.
In the case where the offshore wind power system is in a build phase, the selection module 120 may be configured to select one of the Beidou terminal and the anemometer based only on the availability of the communication link of the Beidou communication system with the remote input/output module. Therefore, under the condition that the offshore wind power system is in a construction stage, the availability of the communication link between the SCADA system and the remote input/output module is not required to be judged, but only the availability of the communication link between the Beidou communication system and the remote input/output module is judged, and because the SCADA system needs to be matched with the remote input/output module to operate, the SCADA system is not required to be selected in the construction stage of the offshore wind power system in which the SCADA system and/or the remote input/output module is not available, but only one of the Beidou terminal and the anemometer is selected, so that the operation efficiency is improved.
In the case where the offshore wind power system is in a construction phase, the communication module 130 may be configured to perform a typhoon resistant strategy by communicating with the typhoon resistant controller based on a selected one of the Beidou terminal and the anemometer. According to the control method of the offshore wind power system, one of the Beidou terminal and the anemometer can be selected based on the availability of the communication link of the Beidou communication system and the remote input/output module, and the typhoon resistance strategy is executed based on the selected one of the Beidou terminal and the anemometer, so that typhoon resistance of the offshore wind power system during a construction stage can be realized.
In the case where the offshore wind system is in an operational phase, the power module 110 may be configured to determine whether the power grid is powered down when a typhoon warning is received, to check whether a communication link between the SCADA system and the Beidou communication system and the remote input/output module is available in response to determining that the power grid is powered down, and to power at least one of the remote input/output module, the anti-typhoon controller, the Beidou communication system, and the anemometer in the offshore wind system via the battery. Thus, it may be determined first whether the grid is powered down before performing other processing, thereby more effectively coping with typhoons. In addition, when a typhoon is encountered, the control method of the offshore wind power system according to the embodiment of the present disclosure may first check the availability of the communication links of the SCADA system and the beidou communication system with the remote input/output module before performing the typhoon resistant operation, so that when one of the communication links of the SCADA system and the remote input/output module and the beidou communication system is unavailable, communication is not performed through the corresponding communication link, and thus, the communication efficiency of the typhoon resistant operation may be improved, and unnecessary time loss may be avoided.
In addition, the power module 110 may be further configured to determine whether the diesel generator is operating in response to determining that the power grid is powered down, switch in the photovoltaic power generation system in response to determining that the diesel generator is not operating, and charge a battery of a wind turbine generator of the offshore wind power system and a battery of the diesel generator of the offshore wind power system using the photovoltaic power generation system, and switch out the photovoltaic power generation system in response to determining that the power grid is not powered down or that the diesel generator is operating. In addition, the power module is further configured to charge a battery of a wind turbine generator of the offshore wind power system and a battery of the diesel generator using the diesel generator in response to determining that the diesel generator is operating. Therefore, when the offshore power generation unit is off-grid for a long time, the off-grid standby time of the diesel generator can be prolonged, and the diesel reserve of the diesel generator can be reduced.
In the case where the offshore wind system is in an operational phase, the selection module 120 may be configured to select the SCADA system to communicate with the typhoon resistant controller via the remote input/output module when a communication link of the SCADA system with the remote input/output module is available. For example, when a communication link between the SCADA system and the remote input/output module is available, an anti-typhoon command provided by the anti-typhoon controller can be transmitted to the remote input/output (I/O) module of the unit control system through a ring network switch of the unit control system by the SCADA system as a central control, a relay of the fan controller is controlled to be closed by the remote I/O module, a 24V battery of the wind generating set provides an input 24V Direct Current (DC) power supply to the fan controller, the fan controller is awakened, the diesel engine is started by the fan controller, and a breaker of the diesel engine is controlled to be closed, so that the anti-typhoon command provided by the anti-typhoon controller can finally realize anti-typhoon operation of the wind generating set through the SCADA system and the fan controller. Furthermore, the selection module 120 may be further configured to select one of the Beidou terminal and the anemometer to communicate with the typhoon resistant controller based only on the availability of the Beidou communication system when the communication link of the SCADA system with the remote input/output module is unavailable.
The selection module 120 may be configured to select the Beidou terminal when the communication link of the Beidou communication system with the remote input/output module is available and to select the anemometer when the communication link of the Beidou communication system with the remote input/output module is not available, whether in the offshore wind power system is in a construction phase or in the case that the communication link of the SCADA system with the remote input/output module is not available.
For example, the Beidou command machine of the Beidou communication system can send a remote control instruction to the Beidou server (for example, a Beidou satellite), the Beidou server can send a starting instruction to the Beidou terminal after receiving the remote control instruction, and the Beidou terminal can feed back a successful receiving instruction to the Beidou command machine through the Beidou server after receiving the starting instruction and can establish communication with the anti-station controller. The anti-station controller can establish communication with a ring network switch and a remote I/O module of the unit control system, and the remote I/O module controls the relay of the fan controller to be closed so as to wake up the fan controller. The fan controller can start the diesel engine and control the breaker of the diesel engine to be switched on, so that the typhoon-resistant command provided by the typhoon-resistant controller can finally realize typhoon-resistant operation of the wind driven generator through the Beidou communication system and the fan controller. For another example, the anemometer may detect the current wind speed in real time and feed it back to the anti-stage controller. When the wind speed reaches the typhoon-resistant triggering condition, the typhoon-resistant controller can be communicated with a remote I/O module of the unit control system, so that the remote I/O module controls the relay, a 24V storage battery of the wind generating set provides an input 24V DC power supply for the fan controller, and the fan controller is awakened. The fan controller starts the diesel engine and controls the breaker of the diesel engine to be switched on, so that the typhoon-resistant command provided by the typhoon-resistant controller can finally realize typhoon-resistant operation of the wind driven generator through the anemometer and the fan controller. Thus, the offshore wind turbine according to the embodiment of the present disclosure can reliably perform the typhoon-resistant operation, regardless of the construction stage or the operation stage of the offshore wind turbine.
