Detailed ways

Various example embodiments will now be described more fully with reference to the accompanying drawings, in which some example embodiments are shown.

FIG. 1 shows a flowchart of a typhoon warning method for a wind farm according to an exemplary embodiment of the present invention.

Referring to FIG. 1, in step S10, typhoon-related data is acquired.

As an example, the typhoon-related data may include, but is not limited to, at least one of the following items: movement path of the typhoon, wind speed of the typhoon, wind direction of the typhoon, gust information, rainfall, lightning information, information of at least one wind circle of the typhoon, The time at which the at least one wind circle arrives at the wind farm.

In a preferred example, typhoon related data can be obtained from a typhoon data source outside the wind farm through the reverse isolation device, for example, typhoon related data can be obtained from a typhoon data source outside the wind farm through the reverse isolation device via the Internet. Here, the typhoon data source may be a provider of typhoon-related data, which may obtain and provide typhoon-related data from a relevant meteorological unit or an Internet platform.

Preferably, the steps of determining the typhoon warning level of the wind farm and determining the early warning strategy of the wind farm for typhoons can be performed inside the wind farm, that is, the determination of the typhoon warning level of the wind farm and the determination of the typhoon warning level of the wind farm based on the local area network inside the wind farm are performed. steps of an early warning strategy. Here, the reverse isolation device, as a device inside the wind farm, can be used to realize the physical isolation between the inside and the outside of the wind farm, which can not only ensure the security of the communication inside the wind farm, but also effectively prevent the data from outside the wind farm. vent.

In step S20, a typhoon warning level of the wind farm is determined based on the wind farm related data and the acquired typhoon related data.

As an example, a SCADA (supervisory control and data acquisition, supervisory control and data acquisition) system may be arranged in the wind farm. The SCADA system can perform data acquisition and control instructions for the wind turbines in the wind farm, and can be used on its monitoring platform. Display the operating status and typhoon-related data of the wind turbine for the staff to monitor. In this case, the location of the wind farm can be obtained from the SCADA system.

The typhoon early warning method for a wind farm according to an exemplary embodiment of the present invention may analyze and process typhoon-related data obtained from a typhoon data source outside the wind farm and wind farm-related data obtained from a SCADA system of the wind farm to determine the typhoon warning strategy. As a non-limiting example, a typhoon warning method for a wind farm according to an exemplary embodiment of the present invention may be implemented in a SCADA system of the wind farm.

Preferably, the wind farm related data may include the location of the wind farm. In this case, the step of determining the typhoon warning level of the wind farm based on the wind farm related data and the acquired typhoon related data may include: according to whether the typhoon related data is acquired The data and whether the moving path of the typhoon passes through the location of the wind farm and/or the wind circle level of the typhoon where the wind farm is located determines the typhoon warning level. Here, the typhoon warning level can indicate the impact of the typhoon on the wind farm. The higher the warning level of the typhoon, the greater the impact of the typhoon on the wind farm.

As an example, the typhoon warning levels from low to high may include, but are not limited to: no typhoon warning, first-grade typhoon warning, second-grade typhoon warning, third-grade typhoon warning, and fourth-grade typhoon warning. The following is an introduction to the determination of each typhoon warning level.

For example, the method of determining no typhoon warning may be: when no typhoon-related data is obtained, it can be indicated that there is no typhoon, and when there is no typhoon, it can be determined that the typhoon warning level is no typhoon warning.

The method of determining the first-class early warning of typhoon can be: when the moving path of the typhoon does not pass the location of the wind farm, that is, when the location of the wind farm is outside the range covered by the set wind circle on the moving path of the typhoon, it can be determined. The typhoon warning level is the first typhoon warning. As an example, the set wind circle may refer to the wind circle of the first level (ie, the wind circle with the lowest average wind force in the typhoon), but the present invention is not limited to this, and may also refer to the wind circle of other levels. For example, when the location of the wind farm is not within the range covered by the first-level wind circle in the moving path of the typhoon, the typhoon warning level may be determined as the first-level typhoon warning.

The method of determining the second-level early warning of typhoon may be: in an example, when the moving path of the typhoon passes the location of the wind farm, if the wind circle level of the typhoon where the wind farm is located is the first level, that is, when the typhoon The moving path passes through the location of the wind farm, and the location of the wind farm is within the range covered by the wind circle of the first level on the moving path of the typhoon (at this time, the location of the wind farm should also be covered by the wind circle of the second level. outside the range), the typhoon warning level is determined to be the second-level typhoon warning. In another example, when the moving path of the typhoon passes through the location of the wind farm, if the time for a predetermined wind circle in the at least one wind circle of the typhoon to reach the wind farm is greater than the first set time, the typhoon warning level may be determined It is a second-level typhoon warning. Here, the predetermined wind circle may refer to any wind circle in the at least one wind circle of the typhoon.

The method of determining the third-level typhoon early warning can be: in an example, when the moving path of the typhoon passes the location of the wind farm, if the wind circle level of the typhoon where the wind farm is located is the second level, that is, when the typhoon The moving path of the wind farm passes through the location of the wind farm, and the location of the wind farm is within the range covered by the second-level wind circle on the moving path of the typhoon (at this time, the location of the wind farm should also be covered by the third-level wind circle). outside the range), the typhoon warning level is determined to be a typhoon warning level three. Here, the average wind force of the wind circle of the second level may be greater than the average wind force of the wind circle of the first level. In another example, when the moving path of the typhoon passes through the location of the wind farm, if the time for a predetermined wind circle in the at least one wind circle of the typhoon to reach the wind farm is less than the first set time and greater than the second set time, Then it can be determined that the typhoon warning level is a typhoon warning level three. Here, the time length of the second set time may be greater than the time length of the first set time.

The way to determine the typhoon level 4 early warning may be: in an example, when the moving path of the typhoon passes the location of the wind farm, if the wind circle level of the typhoon where the wind farm location is located is the third level, that is, when the typhoon When the moving path of the typhoon passes through the location of the wind farm, and the location of the wind farm is within the range covered by the third-level wind circle on the moving path of the typhoon, the typhoon warning level can be determined to be the fourth-level typhoon warning. Here, the average wind force of the wind circle of the third level may be greater than the average wind force of the wind circle of the second level. In another example, when the moving path of the typhoon passes through the location of the wind farm, if the time for a predetermined wind circle in the at least one wind circle of the typhoon to reach the wind farm is less than the second set time and greater than the third set time time, it can be determined that the typhoon warning level is a typhoon warning level four. Here, the time length of the first set time may be greater than the time length of the second set time.

It should be understood that in the exemplary embodiment of the present invention, the classification of typhoon warning levels into five levels is only an example, and those skilled in the art can adjust the division of typhoon warning levels according to the actual operation of the wind farm and the needs of the owner, and also The naming of the typhoon warning level can be modified. In addition, those skilled in the art can also adjust the early warning strategy corresponding to each typhoon early warning level, so that it can not only maximize the power generation time of the wind turbine, but also ensure the safe operation of the wind turbine.

In step S30, an early warning strategy of the wind farm for typhoons is determined according to the determined typhoon warning level of the wind farm. Preferably, different typhoon warning levels may correspond to different warning strategies. However, the present invention is not limited to this, and the same early warning strategy can also be used for two different typhoon early warning levels. Here, the wind farm's early warning strategy for typhoons may include a control strategy for wind turbines in the wind farm and/or an early warning and deployment strategy for the wind farm's operation and maintenance personnel.

For example, the early warning strategy corresponding to no typhoon warning and the early warning strategy corresponding to the first-level typhoon warning can both be maintaining the current operating state of the wind turbines in the wind farm.

The early warning strategy corresponding to the second-level typhoon early warning can be to control the wind turbines in the wind farm to perform a shutdown self-check at the first predetermined time before the first-level wind circle of the typhoon reaches the wind farm, and after the shutdown self-check is completed Afterwards, the wind turbine is controlled to resume operation, and/or the information for instructing the manual operation and maintenance of the wind turbine is displayed to the operation and maintenance personnel of the wind farm.

It should be understood that when it is predicted that the wind circle of the first level of the typhoon will pass the location of the wind farm, there is still a long time before the wind circle of the first level reaches the location of the wind farm. As an example, the first predetermined time The corresponding time length may be ten hours, dozens of hours, several days or even longer, so that the wind farm has sufficient preparation time. At this time, the wind turbine can be controlled to perform self-check to ensure the safety of the wind turbine when the typhoon comes. Optionally, the operation and maintenance personnel can also be prompted to enter the emergency response process (that is, the operation and maintenance personnel are prompted to arrive at their respective positions to prepare for the arrival of the typhoon), and problems can be detected during the self-inspection process of controlling the wind turbine. When the problem occurs, the operation and maintenance personnel responsible for the problem of the wind turbine will be prompted to deal with it in time.

As an example, the self-inspection of the wind turbine may include, but is not limited to, detecting the status, fault information, etc. of each component of the wind turbine, and the related data of the self-inspection (such as information indicating the state of each component, fault information, indication information on whether the self-test is completed) is stored.

As an example, the self-test of the wind turbine may include, but is not limited to, at least one of the following items: pitch emergency feathering function test, pitch locking pin locking function test, yaw braking mechanism function test, yaw drive mechanism Function test, monitoring of yaw twisted cable angle, fault status of anemometer and vane, communication detection.

The early warning strategy corresponding to the third-level typhoon early warning may be to control the wind turbines in the wind farm to enter the typhoon control mode at a second predetermined time before the wind circle of the second level of the typhoon reaches the wind farm, and/or to the wind farm. of operation and maintenance personnel display information related to typhoons.

Preferably, the time length corresponding to the second predetermined time may be less than the time length corresponding to the first predetermined time. Generally, the time length corresponding to the second predetermined time may be several hours. At this time, the wind turbines in the wind farm can be controlled to enter the typhoon control mode, and/or display typhoon-related information to wind farm operators. Here, it should be understood that those skilled in the art can adjust the time lengths corresponding to the first predetermined time and the second predetermined time according to the requirements of the wind farm and the owner.

As an example, the typhoon control mode may refer to controlling the stop of the wind turbine and starting the yaw control system, so that when the second-level wind circle of the typhoon reaches the location of the wind farm (or the second-level wind circle of the typhoon reaches the wind power plant) Before the site is located) control the wind turbine to rotate with the wind direction to control the wind turbine for self-protection.

The early warning strategy corresponding to the four-level typhoon early warning may be displaying information indicating whether the typhoon center has reached the wind farm and/or instructing operation and maintenance personnel to perform safety protection.

At this time, the center of the typhoon is about to reach the location of the wind farm. At this time, the operation and maintenance personnel should be reminded to prepare for safety protection. For example, the operation and maintenance personnel should be reminded to stay in a safe area and not go outside. The movement path of the typhoon can also be displayed in real time. And the status of the wind turbines in the wind farm.

Preferably, the typhoon early warning method for a wind farm according to an exemplary embodiment of the present invention may further include: before at least one wind circle of the typhoon reaches the location of the wind farm and/or when the at least one wind circle of the typhoon arrives at the location of the wind farm, displaying The live situation of the typhoon and/or the operation of the wind turbines in the wind farm based on the early warning strategy.

The typhoon includes three wind circles, namely the first-level wind circle 1 and the second-level wind circle. Circle 2 and Wind Circle 3 of the third level. Here, the average wind power of the wind ring 1 of the first level is smaller than the average wind power of the wind ring 2 of the second level, the average wind power of the wind ring 2 of the second level is smaller than the average wind power of the wind ring 3 of the third level, and the average wind power of the wind ring 3 of the third level The area covered by the wind ring 1 is larger than the area covered by the wind ring 2 of the second level, and the area covered by the wind ring 2 of the second level is larger than that of the wind ring 3 of the third level.

Point A, Point B, Point C, and Point D are the selected points on the boundary of the wind farm, and the area surrounded by lines connecting the above points in sequence is the location of the wind farm. Whether there is a typhoon and whether the movement path of the typhoon passes through the location of the wind farm and/or the wind circle level of the typhoon where the wind farm is located determines the typhoon warning level, and further determines the warning strategy corresponding to the typhoon warning level.

In a preferred example, the typhoon data acquisition module 10 can acquire typhoon-related data from a typhoon data source outside the wind farm through the reverse isolation device. The typhoon data source obtains typhoon-related data. Here, the reverse isolation device, as a device inside the wind farm, can be used to realize the physical isolation between the inside and the outside of the wind farm, which can not only ensure the security of the communication inside the wind farm, but also effectively prevent the data from outside the wind farm. vent.

The method of determining the first-class early warning of typhoon can be: when the moving path of the typhoon does not pass the location of the wind farm, that is, when the location of the wind farm is outside the range covered by the predetermined wind circle on the moving path of the typhoon, the typhoon warning level is The determination module 20 may determine that the typhoon warning level is the first-level typhoon warning.

The method of determining the second-level early warning of typhoon may be: in an example, when the moving path of the typhoon passes the location of the wind farm, if the wind circle level of the typhoon where the wind farm is located is the first level, that is, when the typhoon The moving path passes through the location of the wind farm, and the location of the wind farm is within the range covered by the wind circle of the first level on the moving path of the typhoon (at this time, the location of the wind farm should also be covered by the wind circle of the second level. outside the range), the typhoon warning level determination module 20 may determine that the typhoon warning level is the second-level typhoon warning. In another example, when the moving path of the typhoon passes through the location of the wind farm, if the time for a predetermined wind circle in the at least one wind circle of the typhoon to reach the wind farm is greater than the first set time, the typhoon warning level determination module 20 It can be determined that the typhoon warning level is the second-level typhoon warning. Here, the predetermined wind circle may refer to any wind circle in the at least one wind circle of the typhoon.

The way to determine the third-level typhoon early warning can be: in an example, when the moving path of the typhoon passes the location of the wind farm, if the wind circle level of the typhoon where the wind farm is located is the second level, that is, when the typhoon The moving path passes through the location of the wind farm, and the location of the wind farm is within the range covered by the second-level wind circle on the moving path of the typhoon (at this time, the location of the wind farm should also be covered by the third-level wind circle). outside the range), the typhoon warning level determination module 20 may determine that the typhoon warning level is a typhoon warning level three. Here, the average wind force of the wind circle of the second level may be greater than the average wind force of the wind circle of the first level. In another example, when the moving path of the typhoon passes through the location of the wind farm, if the time for a predetermined wind circle in the at least one wind circle of the typhoon to reach the wind farm is less than the first set time and greater than the second set time, Then, the typhoon early warning level determination module 20 can determine that the typhoon early warning level is a typhoon early warning level three. Here, the time length of the second set time may be greater than the time length of the first set time.

Here, the average wind force of the wind circle of the third level may be greater than the average wind force of the wind circle of the second level. In another example, when the moving path of the typhoon passes through the location of the wind farm, if the time for a predetermined wind circle in the at least one wind circle of the typhoon to reach the wind farm is less than the second set time and greater than the third set time time, the typhoon warning level determination module 20 may determine that the typhoon warning level is a typhoon warning level four.
