Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
In the embodiment of the invention, the intelligent transformer substation adopts advanced, reliable, integrated and environment-friendly intelligent equipment, and automatically completes basic functions such as information acquisition, measurement, control, protection, metering, detection and the like by taking total-station information digitization, communication platform networking and information sharing standardization as basic requirements, and meanwhile, has the transformer substation supporting advanced functions such as real-time automatic control, intelligent regulation, online analysis and decision making, cooperative interaction and the like of a power grid.

Example one
Fig. 1a is a flowchart of a method for checking a control process of an intelligent substation according to an embodiment of the present invention, and fig. 1b is a schematic diagram of a network structure of the intelligent substation according to the embodiment of the present invention, where this embodiment is applicable to a situation of checking a five-prevention logic of the intelligent substation, and the method may be executed by a device for checking a control process of an intelligent substation, and specifically includes the following steps:
and 110, acquiring a station control layer message sent by a station control layer of the intelligent substation to the interval measurement and control device, and acquiring an interval remote control command.
In the embodiment of the invention, the intelligent substation comprises a plurality of interval measurement and control devices, and a plurality of five-prevention objects are correspondingly arranged below each interval measurement and control device.
The intelligent transformer substation adopts advanced, reliable, integrated and environment-friendly intelligent equipment, takes total station information digitization, communication platform networking and information sharing standardization as basic requirements, automatically completes basic functions of information acquisition, measurement, control, protection, metering, detection and the like, and simultaneously has advanced functions of supporting real-time automatic control, intelligent adjustment, on-line analysis decision, cooperative interaction and the like of a power grid. In an intelligent substation, traditional cable connection is not applied to engineering any more, but is replaced by an optical fiber cable, and a large number of electronic elements with high integration and low power consumption are used in various electronic devices.
The intelligent substation system is divided into 3 layers: a process layer, a spacer layer, and a station control layer. The process layer comprises intelligent equipment consisting of primary equipment and intelligent components, a merging unit and an intelligent terminal, and related functions of distribution, transformation, transmission, measurement, control, protection, metering, state monitoring and the like of the electric energy of the transformer substation are completed. The intelligent component is a flexibly configured physical device and can comprise one or more of a measuring unit, a control unit, a protection unit, a metering unit and a state monitoring unit. The bay level equipment generally refers to secondary equipment such as a relay protection device, a measurement and control device, a fault recording device and the like, and realizes the function of using data of one bay and acting on the bay primary equipment, namely, the bay level equipment is communicated with various remote input/output, intelligent sensors and controllers. The station control layer comprises subsystems such as an automation system, a station domain control system, a communication system and a time synchronization system, realizes measurement and control functions facing a whole station or more than one primary device, and completes related functions such as data acquisition and supervisory control (SCA-DA), operation locking, synchronous phasor acquisition, electric energy acquisition and protection information management.
In the embodiment of the invention, the station control layer refers to station control layer equipment of an intelligent substation automation system, the interval measurement and control device is interval layer equipment, and the five-prevention object is process layer equipment. Wherein, intelligent substation automation system station accuse layer equipment includes: the system comprises a monitoring host, a data communication gateway, a data server, a comprehensive application server, an operator station, an engineer workstation, a PMU data concentrator, a plan management terminal and the like; the spacer layer apparatus includes: a relay protection device, a measurement and control device, a fault recording device, a network recording analyzer, a stability and control device and the like; the process layer device includes: merging unit, intelligent terminal, intelligent component, switch etc..
The substation network can be logically divided into: station control layer network, interval layer network, and process layer network. The total station communication is composed of high-speed industrial Ethernet. The station control layer network is a network between the spacer layer equipment and the station control layer equipment, and realizes data transmission inside the station control layer and between the station control layer and the spacer layer; the process layer network is a network between the spacer layer equipment and the process layer equipment, and realizes data transmission between the spacer layer equipment and the process layer equipment; the communication between the devices in the interval layer can be mapped to a station control layer network physically, and also can be mapped to a process layer network physically.
The station control layer network equipment comprises a station control layer central switch and an interval switch. The central switch of the station control layer is connected with a data communication gateway machine, a monitoring host, a comprehensive application server, a data server and other equipment, and protection, measurement and control and other intelligent electronic equipment in the interval switch link interval. The interval switches and the central switches are connected into the same physical network through optical fibers. As mentioned above, the network communication protocol between the station control layer and the bay layer uses MMS, and is therefore also referred to as MMS network. The network can be divided into different logical segments, i.e. different channels, by dividing VLANs (virtual local area networks).
The process layer network comprises a GOOSE network and an SV network. GOOSE networks are used for status and control data exchange between spacer and process level devices. The GOOSE network is generally configured according to voltage class, double networks are adopted for voltage class above 220kV, and a GOOSE point-to-point communication mode is adopted between the protection device and the intelligent terminal at the interval. The SV network is used for transmitting sampling values between the spacing layer and the process layer equipment, and SV data is accessed between the protection device and the merging unit of the spacing layer in a point-to-point mode. Wherein, GOOSE network and SV network refer to two communication protocols commonly used in the power grid.
In the embodiment of the invention, the station control layer, the spacing layer and the process layer are interconnected through the messages of the MMS, GOOSE and SE protocols, the station control layer sends the control command to the spacing layer in the form of the MMS message, further sends the corresponding control command to the equipment of the process layer in the form of the GOOSE and SE messages through the spacing layer, and the process layer feeds back the state of the process layer to the spacing layer through the GOOSE and SE messages and further feeds back the state to the station control layer.
And step 120, determining the target five-prevention object and the expected state of the target five-prevention object based on the interval remote control command.
In the embodiment of the invention, the interval remote control command sent by the station control layer to the bay layer is a set of control commands for a plurality of interval measurement and control devices and five-prevention objects, that is, the control commands for a plurality of five-prevention objects are included in a single interval remote control command. In this step, it is necessary to determine the five-prevention object targeted in the interval remote control command as the target five-prevention object, and determine the expected state of each target five-prevention object, where the expected state refers to the specific content of the modification command for the target five-prevention object in the interval remote control command, that is, the state to which the target five-prevention object needs to be modified. For example: when the target fail-safe object is an electrical switch, the expected state of the corresponding electrical switch is an on state or an off state if the object has two states of on and off. It should be noted that the expected state is not related to the current state of the five-prevention object, but only to the interval remote control command issued by the station control layer to the interval layer. With the foregoing electrical switch, the present state may be an on state, and the expected state may be the same on state as the present state or an off state different from the present state.
And step 130, acquiring the five-prevention logic of the target five-prevention object based on the target five-prevention object and the expected state.
The five-prevention logic of the target five-prevention object refers to a logic relation formula of states which the other five-prevention objects which are key to the target five-prevention object need to be in when the target five-prevention object needs to be changed, and the target five-prevention object can be correctly placed in an expected state corresponding to the interval remote control command only when the other five-prevention objects meet the logic relation. In addition, the five-prevention logic of the target five-prevention object can have one or more pieces. For example: the electrical switch has at least one five-prevention logic corresponding to the on state and at least one five-prevention logic corresponding to the off state, and the on state and/or the off state may have other five-prevention logics besides the one five-prevention logic.
And 140, acquiring process layer messages between the interval measurement and control device of the intelligent substation and the five-prevention objects, and acquiring the current state of each five-prevention object.
In the embodiment of the invention, the five-prevention object of the intelligent substation sends the state of the five-prevention object to the interval measurement and control device and the station control layer at regular time or in response to the command of the interval measurement and control device and the station control layer, so that the current state of each five-prevention object can be obtained based on the process layer message sent by the five-prevention object.
For example, special information such as an address for characterizing the five-prevention object can be further included in the process layer message sent by the five-prevention object.
And 150, judging whether the check is passed according to the current state of each five-prevention object and the five-prevention logic.
By comparing the five-prevention logic of the target five-prevention object with the current state of each five-prevention object, whether the five-prevention logic of the target five-prevention object is correct can be judged.
According to the technical scheme, the interval remote control command is obtained from the station control layer message, the target five-prevention object required to be remotely controlled is further judged, the five-prevention logic corresponding to the target five-prevention object is determined, then the current state of each five-prevention object is obtained from the process layer message, and whether the five-prevention logic setting of the target five-prevention object is correct or not can be judged by combining the five-prevention logic, so that the five-prevention logic verification of the target five-prevention object is realized, the interval remote control command is prevented from being executed under the condition that the five-prevention logic of the target object is wrong or the current condition of the intelligent substation does not meet the interval remote control command, and the operation safety of the intelligent substation is improved.
Example two
Fig. 2 is a flowchart of a method for checking a control process of an intelligent substation according to a second embodiment of the present invention. The embodiment is a refinement based on the first embodiment, and describes in detail how to determine whether the five-prevention logic in the control process of the intelligent substation is wrong. The method specifically comprises the following steps:
step 201, importing a configuration description file of the intelligent substation.
The configuration description file of the intelligent Substation may be referred to as an SCD (Substation configuration description, SCD) file for short, and the Substation configuration description file describes each isolated intelligent electronic device in the intelligent Substation and a logical connection between each intelligent electronic device, and also describes example configurations and communication parameters of all the intelligent electronic devices, communication configurations between each intelligent electronic device, and a primary system structure of the Substation, and can completely describe how each isolated intelligent electronic device is integrated into a process of a Substation automation system with complete functions. Therefore, the substation configuration description file can be used as an important basis for the operation configuration of the secondary system of the substation, and in the reconstruction and extension project of the substation, the real-time control and analysis of the substation configuration description file can make more accurate judgment on the daily operation and fault diagnosis of the substation and perform maintenance operation on each electrical device and the secondary protection circuit in the substation in time.
The configuration description file contains information of the secondary device, and the information of the secondary device may include a device name, a device description, a manufacturer, a device model, a virtual terminal check code CRC, a model version, and the like. It should be noted that the secondary device is a device that is not directly connected with the electric energy in the substation, and is generally an auxiliary device that controls, protects, monitors, measures, and adjusts the operation of the primary device in the substation, and the primary device is a device used in a main system of power generation, transmission, and distribution in the substation, such as a generator, a transformer, a circuit breaker, a disconnector, a bus, a power cable, and a transmission line.
Step 202, acquiring index paths of each interval measurement and control device and the five-prevention object based on the configuration description file.
The information of each interval measurement and control device and the five-prevention object is recorded in a configuration description file of the intelligent substation, different interval measurement and control devices and different five-prevention objects correspond to different index paths in the configuration description file, and the index paths are unique.
In other embodiments, in addition to the index path, the identifier may be a unique identifier such as an equipment ID set for the interval measurement and control device and the five-prevention object.
And 203, acquiring a station control layer message sent by a station control layer of the intelligent substation to the interval measurement and control device.
In this embodiment, the specific explanatory contents refer to the step 110 portion in the first embodiment, consistent with the step 110 in the first embodiment.
The method for acquiring the station control layer message may be various, and a transfer device may be arranged between the station control layer and the interval measurement and control device for reading, or a method for reading from the station control layer or from the storage of the interval test device, and the like, which is not described herein in detail as long as the method for acquiring the station control layer message in the embodiment of the present invention can be implemented.
And step 204, respectively acquiring corresponding interval remote control commands based on each index path and the station control layer messages.
In the embodiment of the invention, a station control layer message sent by a station control layer contains interval remote control commands for a plurality of interval measurement and control devices and five-prevention objects, different parts in the station control layer message correspond to different index paths, namely, different parts correspond to different interval measurement and control devices and five-prevention objects, and in the step, the interval remote control commands for different interval measurement and control devices and five-prevention objects need to be distinguished and extracted. The index path generation here refers to the index paths of all five-prevention objects and the interval measurement and control devices.
Step 205, determining an index path of the interval remote control command.
In this step, the determination of the index path may be performed according to an interval remote control command in the station control layer, or may be performed from the database after determining a five-prevention object corresponding to the interval remote control command, where the obtaining manner is not specifically limited.
The index path generation here refers to an index path of a five-prevention object corresponding to the interval remote control command.
And step 206, determining the active five-prevention object based on the index path as a target five-prevention object.
In the foregoing steps, the index path of the five-prevention object targeted by the interval remote control command is determined, so that the specific five-prevention object targeted by the specific interval remote control command can be acquired, and the set of the specific five-prevention object is taken as the target five-prevention object. The index path generation here refers to an index path of a five-prevention object corresponding to an interval remote control command.
And step 207, determining an interval remote control command of each target five-prevention object based on the index path.
The index path generation here refers to an index path of a five-prevention object corresponding to the interval remote control command, and the interval remote control command is associated with an index path of a target five-prevention object.
And 208, correspondingly extracting the remote control instruction of the target five-prevention object from the interval remote control command of each target five-prevention object, and determining the expected state of the target five-prevention object.
In this embodiment, the obtaining manner of the expected state of the target five-prevention object is the same as that of step 120 in the first embodiment, and details are not repeated here, and specific explanatory contents refer to the step 120 in the first embodiment.
And step 209, determining an index path of the target five-prevention object. The index path is an index path of the target five-prevention object, and the index path is obtained by taking the target five-prevention object as a keyword.
And step 210, extracting the five-prevention logic of the target five-prevention object from a preset database by taking the index path and the expected state as keywords.
In the embodiment of the invention, a five-prevention logic library with five-prevention objects is constructed in advance, and all that is needed in the step is to extract corresponding five-prevention logic from the five-prevention logic library.
The pre-construction of the five-prevention logic library of the five-prevention objects can be realized by constructing a database, extracting an index path of each five-prevention object from an SCD (substation configuration description) file of the intelligent substation, determining all working states of each five-prevention object, confirming the association relation of each five-prevention object from the SCD file, and editing and storing the five-prevention logic of each working state of each five-prevention object by a management and maintenance worker of the intelligent substation. At this time, it should be noted that there may be more than one five-prevention logic for each five-prevention object, and at this time, all the five-prevention logics need to be listed and filled in the database.
Typical interval objects which can be specifically established in the database comprise line intervals, main transformer intervals, bus coupling subsection intervals and switch intervals. The attributes of the interval object comprise an interval type, a voltage level and a wiring type. And establishing five-prevention objects including a switch, a disconnecting link, a grounding switch and an analog quantity in each typical interval. And establishing a five-prevention logical relationship of each five-prevention object, wherein the five-prevention logical relationship comprises the states which are currently met by other five-prevention objects when each five-prevention object is converted from the current state to the next expected state.
The line interval of 110kV single bus connection is taken as an example for explanation, and a line interval object is established in a database, wherein the attributes of the line interval object comprise that the interval type is a line, the voltage class is 110kV, and the connection type is single bus connection. And then establishing a five-prevention object in the line interval object, wherein the five-prevention object comprises a bus side disconnecting link, a bus side grounding knife, a switch side grounding knife, a switch side disconnecting link, a line side grounding knife, a line current analog quantity and a bus voltage analog quantity. And then establishing a five-prevention logic for switching on the switch, wherein if the current state of the line switch is in an open position and the expected state is in a closed position, the five-prevention logic for switching on the line switch is that the adjacent side disconnecting links are in the closed position or in the open position, and the five-prevention logic can be described as follows: line switch closing = (busbar side disconnecting link = =1& & switching side disconnecting link = = 1) | (busbar side disconnecting link = =0& & switching side disconnecting link = = 0). Therefore, five-prevention check logic of other interval types such as main transformer intervals, bus-coupled subsection intervals, switch intervals and the like can be established similarly.
And step 211, acquiring process layer messages between the interval measurement and control device of the intelligent substation and the five-prevention objects, and acquiring the current state of each five-prevention object.
The intelligent substation adopts message form to communicate among the station control layer, the spacer layer and the process layer, the station control layer communicates with the spacer layer through MMS message, and the spacer layer communicates with the process layer through GOOSE message and SV message. The spacer layer mainly refers to a spacing measurement and control device, and the process layer mainly refers to a five-prevention object. In the embodiment of the invention, the process layer message between the interval measurement and control device and the five-prevention object needs to be acquired, and then the process layer message is analyzed, so that the self state feedback message sent by each five-prevention object to the interval measurement and control device is acquired, and the current state of each five-prevention object is determined.
And step 212, acquiring a remote control permission signal sent by the interval measurement and control device from the process layer message.
When the interval measurement and control device makes a control command on the five-prevention object, a remote control permission signal is required to be output to the five-prevention object, and the remote control permission signal can represent that remote control is permitted or prohibited, so that whether the five-prevention object responds to a received process layer signal or not is controlled, the reliability of the action of the five-prevention object is effectively improved, misoperation is avoided, and the like.
And step 213, judging whether the check is passed according to the current state of each five-prevention object, the remote control permission signal and the five-prevention logic.
And finally, acquiring the five-prevention logic of the target five-prevention object, and the remote control permission signal and the current state of each five-prevention object sent by the interval measurement and control device in the previous step, so that whether the remote control permission signal and the current state of each five-prevention object accord with the five-prevention logic of the target five-prevention object or not can be judged, and whether the check passes or not can be judged.
Optionally, when the current state of each five-prevention object meets the five-prevention logic and the remote control permission signal is in a permission state, judging that the checking is passed;
when the current state of at least one five-prevention object does not meet the five-prevention logic and the remote control permission signal is in a forbidden state, judging that the checking is passed;
when the current state of each five-prevention object meets the five-prevention logic and the remote control permission signal is in a forbidden state, judging that the checking does not pass;
and when the current state of at least one five-prevention object does not meet the five-prevention logic and the remote control permission signal is in a permission state, judging that the checking does not pass.
Optionally, a corresponding warning signal may be sent out after the judgment that the check fails, so as to prompt a maintenance worker to check the abnormal operation of the intelligent substation in time.
Further, in an optional embodiment, the position where the abnormality occurs may be determined, so as to further facilitate maintenance personnel to maintain the intelligent substation.
