Description

Technical Field

[0001] The invention relates to the field of fault location, and in particular to a full-cycle fault diagnosis method and device for a security control system function test command. Background Art

[0002] The safety and stability control system (security control system) is an important line of defense to ensure the safe and stable operation of the power grid. A complete safety and stability control strategy (hereinafter referred to as the security control strategy) can prevent the spread of faults by emergency control to cut off units and loads before the system becomes critically unstable, while allowing the loss of 1-2 components or part of the load, and can effectively avoid large-scale power outages in the power grid.

[0003] Security control systems are diverse in types, complex in structure, have great regional differences, and have strong targeted functions. How to conveniently and accurately check the functions and performance of multi-site security control systems is a difficult point in stability control testing. Due to the continuous advancement of UHV construction, the operation mode of the power system is changeable, the number of sections is increasing, the control rules are becoming more and more complicated, and when the grid topology and operation mode change, the emergence of a large number of unknown fault conditions makes on-site inspection of the security control system function also a very complex and difficult task. If you simply rely on independent site testers to increase the volume of the security control system, it is inevitable that there will be the possibility of missing risk factors, and there will be problems such as high work intensity and low testing efficiency. Especially when encountering abnormal situations such as message loss and redundancy during the test process, it is impossible to reproduce and record the test process in time, so it is impossible to locate the corresponding fault point and faulty equipment.

[0051] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0052] Example 1

[0053] To facilitate understanding, first combine Figure 1 The system architecture applicable to the embodiments of the present application is introduced.

[0054] Figure 1 This is a system architecture diagram provided by the embodiment of this application. Please refer to Figure 1 , including a safety and stability control system and a functional test system corresponding to the safety and stability control system. The safety and stability control system includes a safety and stability control main station, an AC control main station and a DC control main station. The installation stability control main station is connected to the AC control main station and the DC control main station respectively. Each AC control main station is connected to the safety and stability control subsystems on multiple execution substations. The execution substation represents a substation on the transmission line in the AC power grid, and sends instructions through the safety and stability control subsystem. Each DC control main station is connected to the safety and stability control subsystems on multiple auxiliary control substations. The auxiliary control substation represents a substation on the transmission line in the DC power grid, and sends instructions through the safety and stability control subsystem.

[0055] The functional test system includes multiple subsystems and a test master station. Each auxiliary control substation and execution substation corresponds to a subsystem. Each subsystem represents a stability control tester. The safety control system tester simulates the equipment in the substation to receive the functional test command issued by the safety and stability control subsystem in the substation, and simulates the generation of functional status feedback information to the safety and stability control subsystem, so as to test the safety and stability control system. The test master station connects with each subsystem to locate faults during the safety and stability control system test.

[0056] like Figure 2 As shown, this embodiment provides a full-cycle fault diagnosis method for a function test command of a security control system, wherein the security control system includes multiple execution substations and multiple co-control substations, each execution substation corresponds to a function tester, and each co-control substation corresponds to a function tester; the function tester is used to simulate electrical equipment, obtain a function test command issued by the execution substation or the co-control substation, and generate status feedback information corresponding to the function test command, including:

[0057] S1. Obtain multiple function test commands of the security control system and status feedback information corresponding to the function test commands.

[0058] An AC test network can be established for the communication between the execution substation and the corresponding subsystem under the AC control master station, and the AC test network transmits data in electrical quantity protocol messages. A DC test network can be established for the communication between the auxiliary control substation and the corresponding subsystem under the DC control master station, and the DC test network transmits data in IEC60044-8 protocol messages.

[0059] The AC test communication network is a network for communication between the execution substation and the security control system functional tester, including the adjustment and cutting commands issued by the execution substation to the security control system functional tester, and the switch position commands issued by the security control system functional tester; the DC test communication network is a network for communication between the auxiliary control substation and the security control system functional tester, including the DC adjustment amount issued by the auxiliary control substation, and the power loss amount issued by the security control system functional tester.

[0060] S2. Construct a command information association table based on multiple functional test commands and status feedback information corresponding to the functional test commands, and construct a full-cycle information list based on the command information association table. The full-cycle information list includes the first field corresponding to the execution substation and the co-control substation, and the first field is empty.

[0061] The command information association table is a semantic association table between the execution substation, the co-control substation and the security control system function tester. It is worth noting that the command information association table should be obtained when the security control system is first used or when the function is normal. Then, based on the command information association table, fault location can be performed in the subsequent maintenance of the security control system.

[0062] A command information association table is formulated according to the content of the security control system function test command transmitted in the AC test network and the DC test network. The command information association table is shown in Table 1.

[0063] Table 1 Command information association table

[0064]

[0065] Table 1 shows two functional test commands extracted from the field test of a security control system of a power grid in southwest China using a stability tester, namely, AB line fault tripping and AB line no fault tripping. Each functional test command forms a corresponding protocol information entry in the AC test network and DC test network between the stability device and the stability tester, that is, AB line fault tripping → subsystem 1-1: 232 → subsystem 1-2: 233 → subsystem 2-1: 00A1: 2 → subsystem 2-2: 00A2: 2 → subsystem 2-2: 00A2: 4 → subsystem 2-1: X → subsystem 1-2: 245 → subsystem 1-1: 244, thereby establishing a command information association table transmitted between the stability system and the stability tester in the two networks in chronological order.

[0066] According to the matching rule table and its protocol information entries, a full-cycle information list of the control command in the two communication layers of the AC test network and the DC test network is established; the full-cycle information list is an empty table that completely corresponds to the rows and columns of the command information association table. The protocol information entry is a row and column formed by arranging the protocol information corresponding to the functional test command in the AC test communication network and the DC test communication network in the protocol information matching rule, and the full-cycle command information list is an empty table that completely corresponds to the rows and columns of the command information association table.

[0067] S3. Acquire the real-time function test command and real-time status feedback information of the security control system, and filter the real-time function test command and real-time status feedback information according to the command information association table to obtain the target function test command and target status feedback information.

[0068] Each monitored message is filtered and classified according to the two protocols, and the protocol information of each message is extracted after grammatical and semantic analysis. For example, for the electrical quantity protocol message, the corresponding point number is extracted from the security control tester as the protocol information, and for the IEC60044-8 message, the data frame is extracted as the protocol information.

[0069] Compare the protocol information of each message with the protocol information entry in the command information association table. If the protocol information of the message matches the protocol information in the protocol information entry, then the one-way transmission of the message between its corresponding communication layer is judged as a qualified command transmission step, and the protocol information of the message is extracted and stored in the full-cycle information list as the information of the security control function test command step, otherwise the message is discarded. For example, the security control tester monitors an electrical quantity protocol message in the AC test network in real time. After comparing the protocol information entry marked by the matching rule, if it is a match, it can be judged that this is a qualified command step sent from the security control system to the security control tester, and the command information corresponding to the electrical quantity protocol message is extracted as the information of the qualified command step.

[0070] S4. Store the target function test command and the target state feedback information in the first field of the full cycle information list. When the information in the full cycle information list meets the fault diagnosis condition, perform fault location.

[0071] S5. Determine the first field in the full-cycle information list that is empty, and locate the fault point according to the empty first field to obtain a full-cycle fault diagnosis result.

[0072] In a possible implementation, the execution substation is a security control subsystem of a substation on an AC line, and the assistance control substation is a security control subsystem of a substation on a DC line.

[0073] In a possible implementation, the function test command of the execution substation is transmitted in an electrical quantity protocol message, and the function test command of the auxiliary control substation is transmitted in an IEC60044-8 protocol message.

[0074] In a possible implementation, obtaining multiple function test commands of a security control system and status feedback information corresponding to the function test commands includes:

[0075] Obtain the function test commands corresponding to each execution substation and the auxiliary control substation in the security control system in the event of line fault tripping and the status feedback information corresponding to the function test commands.

[0076] Obtain the functional test commands and status feedback information corresponding to the functional test commands corresponding to each execution substation and auxiliary control substation in the security control system when the line trips without fault. Each functional test command and status feedback information corresponding to the functional test command has a corresponding time stamp.

[0077] In a possible implementation, a command information association table is constructed according to a plurality of function test commands and status feedback information corresponding to the function test commands, including:

[0078] According to multiple function test commands, the line fault tripping condition, the function test command and the first association relationship between the execution substation / co-control substation are determined, and the first association relationship corresponding to the multiple execution substations and the multiple co-control substations is obtained.

[0079] According to multiple function test commands, the second association relationship between the line fault-free tripping situation, the function test command and the execution substation / co-control substation is determined, and the second association relationship corresponding to the multiple execution substations and the multiple co-control substations is obtained.

[0080] Arrange the first association relationships corresponding to the execution substations in chronological order to obtain a first sequence. Arrange the first association relationships corresponding to the coordination substations in chronological order to obtain a second sequence, and use the first sequence and the second sequence as the first row of information in the command information association table.

[0081] The state feedback information corresponding to the first relationship of the plurality of execution substations is reversely arranged in chronological order to obtain a third sequence. The state feedback information corresponding to the first relationship of the plurality of assistant control substations is reversely arranged in chronological order to obtain a fourth sequence, and the third sequence and the fourth sequence are used as the second row of information in the command information association table.

[0082] Arrange the second association relationships corresponding to the execution substations in chronological order to obtain a fifth sequence. Arrange the second association relationships corresponding to the coordination substations in chronological order to obtain a sixth sequence, and use the fifth sequence and the sixth sequence as the third row of information in the command information association table.

[0083] The state feedback information corresponding to the second relationship of the plurality of execution substations is reversely arranged in chronological order to obtain a seventh sequence. The state feedback information corresponding to the second relationship of the plurality of assistant control substations is reversely arranged in chronological order to obtain an eighth sequence, and the seventh sequence and the eighth sequence are used as the fourth row of information in the command information association table.

[0084] The command information association table is obtained according to the first line of information, the second line of information, the third line of information and the fourth line of information.

[0085] In a possible implementation, constructing a full-cycle information list according to the command information association table includes:

[0086] Determine the first field corresponding to the function test command and the status feedback information in the command information association table, set the first field to be empty, and only retain the format of the command information association table to obtain a full-cycle information list.

[0087] In a possible implementation, a real-time function test command and real-time status feedback information of a security control system are obtained, and the real-time function test command and real-time status feedback information are filtered according to a command information association table to obtain a target function test command and target status feedback information, including:

[0088] Obtain the message sent by the security control system and determine whether the message is an electrical quantity protocol message or an IEC60044-8 protocol message. If so, extract the real-time function test command and real-time status feedback information in the message information; otherwise, discard the message.

[0089] Obtain the fault type and the corresponding substation corresponding to the real-time function test command / real-time status feedback information, and obtain the target fault type and the target substation. The fault type includes line no fault tripping or line fault tripping.

[0090] Determine the functional test command / status feedback information corresponding to the target fault type and the target substation in the command information association table. If the determined functional test command / status feedback information is the same as the real-time functional test command / real-time status feedback information, then the real-time functional test command / real-time status feedback information is used as the target functional test command / target status feedback information.

[0091] In a possible implementation, the target function test command and the target state feedback information are stored in the first field of the full cycle information list, and when the information in the full cycle information list meets the fault diagnosis condition, the fault location is performed, including:

[0092] The target function test command and the target state feedback information are stored in the first field of the full cycle information list in chronological order.

[0093] The target function test command and the target status feedback information are stored in the first field of the full-cycle information list in chronological order, including: traversing all the target function test commands / target status feedback information in chronological order, and determining the first field corresponding to the target fault type and the target substation in the full-cycle information list according to the target fault type and the target substation corresponding to the target function test command and the target status feedback information; and storing the target function test command and the target status feedback information in the corresponding first field.

[0094] When the time interval between the first data stored and the last data stored in the full cycle information list exceeds the set threshold, it is determined that the fault diagnosis condition is met and the fault is located.

[0095] The information of each command step in the full cycle information list is sorted by time, and the time interval between the information of the first command step and the information of the last command step is calculated. If the time interval exceeds the set time, the information of each command step collected in the full cycle information list is extracted to form the full cycle information of the security control system function test and stored and displayed. For example, if the AB line fails and trips, the information is extracted according to the specification information item to obtain: Subsystem 1-1: switch position → Subsystem 1-2: switch position → Subsystem 2-1: power loss → Subsystem 2-2: power loss → Subsystem 2-2: DC regulation → Subsystem 2-1: X → Subsystem 1-2: cut-off → Subsystem 1-1: trip. Among them, X represents an empty field.

[0096] In a possible implementation manner, determining a first field in the full cycle information list that is empty, and locating a fault point according to the first field that is empty, to obtain a full cycle fault diagnosis result includes:

[0097] Determine the first empty field in the full cycle information list and obtain the target field.

[0098] Determine whether the data corresponding to the target field is a functional test command. If so, determine the substation and functional tester corresponding to the functional test command in which the target field is missing, and determine that there is a fault in the data transmission direction from the substation to the functional tester. Otherwise, determine that the data corresponding to the target field is status feedback information, determine the substation and functional tester corresponding to the status feedback information in which the target field is missing, and determine that there is a fault in the data transmission direction from the functional tester to the substation, and obtain the full-cycle fault diagnosis result.

[0099] Detect the empty cells in the full-cycle information list, find the two-end communication equipment subsystem 2-1 corresponding to the cell and send the power loss amount to the cooperative control substation 1, and locate the faulty device as the subsystem 2-1 of the security control system tester according to the sending direction of the information.

[0100] Generally speaking, the setting range is 0 to 0.5 seconds; the command information association table is a semantic association table formed by associating the semantics of the two protocols. The full cycle refers to the time window for the execution of the security control system function, which is fixed at 0.5 seconds.

[0103] The data acquisition module 1 is used to acquire multiple function test commands of the security control system and status feedback information corresponding to the function test commands.

[0104] Construction module 2 is used to construct a command information association table based on multiple functional test commands and status feedback information corresponding to the functional test commands, and to construct a full-cycle information list based on the command information association table. The full-cycle information list includes the first field corresponding to the execution substation and the co-control substation, and the first field is empty.

[0105] The data processing module 3 is used to obtain the real-time function test command and real-time status feedback information of the security control system, and filter the real-time function test command and real-time status feedback information according to the command information association table to obtain the target function test command and target status feedback information.
