Description

Technical Field

[0001] The present application relates to the field of electronic power technology, and in particular to a fault criterion testing system, method, and device for a stabilization control device. Background Art

[0002] The safety and stability control system (hereinafter referred to as the "stability control system") is one of the three lines of defense of the power system. Its action will directly affect whether the power system can operate safely and stably. Whether the stability control system refuses to operate or malfunctions, it will cause serious consequences to the power grid. In recent years, with the large-scale access of new energy and the rapid development of ultra-high voltage AC / DC hybrid cross-regional transmission, the connection between regional power grids has become closer. The characteristics of new forms of power transmission such as large capacity and long distance have made the stability problem of the power system more prominent, and the fault identification of the stability control device has also faced huge challenges. Therefore, the stability control device needs to accurately distinguish between accident forms such as short-circuit fault tripping and no-fault tripping and take corresponding control measures to ensure that the power grid is in good operating condition. Before the stability control device is put into operation, it needs to undergo strict factory testing. Fault identification is its most basic and most critical link.

[0003] Typically, a regional stabilization and control system includes multiple stabilization and control devices, and each stabilization and control device has the function of collecting electrical and switching information from multiple components (lines and transformers) and determining whether the corresponding component has tripped. In addition, component faults can be subdivided into multiple fault types (such as single instantaneous faults, single permanent faults, phase-to-phase faults, and no-fault tripping, etc.), and each fault type includes multiple faults with different phase sequences. Therefore, in order to ensure the comprehensiveness of the stabilization and control device test, it is necessary to consider the cross-combination of different fault types and different phase sequence faults, and perform a traversal test of all faults on each component, which will greatly increase the workload of the fault judgment test.

[0004] In the prior art, the test system is Figure 1 As shown, during factory acceptance, various stabilization and control manufacturers primarily simulate component tripping by inputting electrical quantities into the stabilization and control device using a debugging box and inputting switching quantities via a pressure plate. Manual comparison is then performed to determine whether the stabilization and control device's action message matches the triggered fault type. To verify the next fault type, the pressure plate is manually restored to its initial state and the debugging box is used to reload the specified fault data. This process is repeated until all possible fault combinations have been examined.

[0005] The above method has the following drawbacks for testing the fault criteria of the stabilization control device in the AC / DC large power grid stabilization control system:

[0006] (1) This method mainly simulates component failures by increasing the amount of the debugging box and manually putting and releasing the pressure plate. It cannot guarantee the synchronization of the time coordination of electrical quantities and switching quantities. It is difficult to simulate faults with reclosing and combined faults in a short period of time without modifying the device settings.

[0007] (2) In order to ensure the integrity of the fault judgment test, it is necessary to traverse and scan all fault modes of multiple devices and components. In the actual operation process, it requires the cooperation of multiple people, resulting in a large amount of manpower and time costs;

[0008] (3) The simulated operating conditions are single and it is not possible to easily superimpose disturbances or change the line operating conditions;

[0009] (4) All action messages need to be manually checked, and it is impossible to automatically check and analyze preset faults and action messages in batches. Summary of the Invention

[0077] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clearly understood, the embodiments of the present application are further described in detail below with reference to the accompanying drawings. The illustrative embodiments of the present application and their descriptions are used to explain the present application but are not intended to limit the present application. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application may be combined with each other in any manner.

[0078] Figure 2FIG. 1 is a structural diagram of a fault criterion test system for a stabilization control device provided in an embodiment of the present application. Figure 2 As shown, the fault criterion test system for the stabilization device provided by this application includes:

[0079] Real-time digital simulation device 1, used to provide a fault judgment test model and output switching values ​​and analog values ​​according to the received fault judgment test script;

[0080] Specifically, a real-time digital simulation device (RTDS) is a device that uses a high-performance processor and a dedicated model library to build a device that can output the operating status of a simulation model in real time. This application deploys a fault criterion test model on the real-time digital simulation device 1, executes a fault criterion test script through the model operation software runtime of the real-time digital simulation device 1, and outputs a module of switching and analog quantities according to the fault criterion test script to provide a test signal for testing.

[0081] In one embodiment, if Figure 15 As shown, the real-time digital simulation device 1 includes a power grid module 101, a fault module 102, a disturbance module 103 and a power flow module 104;

[0082] The power grid module 101 is used to output switching values ​​and analog values ​​according to the fault judgment test script;

[0083] Specifically, the power grid module 101 is a primary AC grid model built within the real-time digital simulation device 1, containing the relevant electrical components of the stability control system under test. It can output switching and analog values ​​based on the execution of the fault judgment test script, providing test signals to multiple stability control devices 2 for fault judgment testing. The power grid module 101 includes an AC line model, a transformer model, a generator model, and a load model.

[0084] The fault module 102 is used to generate fault information according to the acquired fault type;

[0085] Specifically, if Figure 12 As shown, the fault types include single-phase instantaneous fault (phase A, phase B, and phase C), single-phase permanent fault (phase A, phase B, and phase C), interphase short circuit fault (phase AB, phase AC, phase BC, and phase ABC), and no-fault tripping. The fault module 102 generates fault information according to the fault type (single-phase instantaneous fault, single-phase permanent fault, interphase short circuit fault, or no-fault tripping), so that the simulation computer 4 simulates the fault scenario according to the fault information.

[0086] The disturbance module 103 is used to generate disturbance information according to the acquired external disturbance amount;

[0087] Specifically, the external disturbance includes a DC component and a higher harmonic component. The disturbance module 103 generates disturbance information based on the acquired external disturbance. It can superimpose the DC component and the higher harmonic component under the current grid operating conditions, set the proportion of the DC component and the harmonic component and the harmonic order, and realize convenient superposition of disturbance.

[0088] The flow module 104 is configured to generate flow information according to the acquired flow mode.

[0089] Specifically, the flow mode is used to indicate the light load / heavy load, power reversal and line maintenance states. The flow module 104 generates flow information according to the acquired flow mode, so that the simulation computer 4 simulates the line conditions according to the flow information, adjusts the active power and reactive power, realizes the flow size, reversal and other mode selection, and changes the line operating conditions.

[0090] Multiple stabilization control devices 2 are connected to the real-time digital simulation device 1 via a sampling board 8 and are used to generate action messages according to the switch quantity and analog quantity;

[0091] Specifically, the stabilization control device 2 is also called a safety and stability control device, which can achieve stable control of the power system. The real-time digital simulation device 1 is connected to multiple stabilization control devices 2 through an interface board (sampling board 8), and the switch quantity and analog quantity used for fault judgment testing are input into multiple stabilization control devices 2 to realize information interaction between the real-time digital simulation device 1 and the stabilization control device 2, wherein the analog quantity is transmitted through the GTAO interface board, and the switch quantity is transmitted through the GTDO interface board. Analog quantities include voltage and current, etc., and switch quantities include switch position signals and protection tripping signals, etc. The stabilization control device 2 automatically generates an action message at the time of fault triggering based on the switch quantity and analog quantity and uploads it to the centralized stabilization control management system 3.

[0092] Each station's stabilization and control device includes a master and slaves. One master can correspond to multiple slaves. The slaves are responsible for sampling and fault diagnosis and sending the obtained information to the master station. The master station will make decisions and issue control measures based on the information.

[0093] The centralized stabilization and control management system 3 is connected to the plurality of stabilization and control devices 2 via the first networking switch 6, and is used to receive the action messages automatically uploaded by the plurality of stabilization and control devices and send the action messages to the simulation computer 4;

[0094] Specifically, the stability control centralized management system, also called the stability control centralized management system (SCMS), can communicate in full duplex with the safety and stability control devices (stability control devices) distributed in various power plants or substations through microwave, carrier, and optical fiber channels, and implement comprehensive monitoring and management of the stability control system plants and substations. The action message automatically generated by the stability control device 2 at the time of fault triggering based on the switch quantity and analog quantity will be automatically uploaded to the stability control centralized management system 3, and will be uniformly sent by the stability control centralized management system 3 to the simulation computer 4 for fault judgment test result verification, which can realize the centralized management of multiple stability control devices 2. The stability control centralized management system 3 is connected to the stability control device 2 and the simulation computer 4 through a networking switch. The networking switch can connect different devices and receive and forward data to the target device through message exchange. The stability control device 2 sends the action message to the stability control centralized management system 3 through the first networking switch 6, and the simulation computer 4 realizes batch download of action messages from the stability control centralized management system 3 through the second networking switch 7. If there is no centralized stabilization and control management system 3, a server is required to receive the action message of each stabilization and control device 2, and multiple stabilization and control devices 2 cannot be centrally managed.

[0095] The simulation computer 4 is connected to the real-time digital simulation device 1 and is connected to the stabilization and control centralized management system 3 through the second networking switch 7, and is used to generate the fault judgment test script according to the fault judgment test model, and to verify the results of the fault judgment test according to the received fault information and the action message.

[0096] Specifically, the simulation computer 4 generates a fault criterion test script based on the fault criterion test model provided by the real-time digital simulation device 1, and then applies the various fault scenarios simulated by the fault criterion test script to the power grid module 101 of the real-time digital simulation device 1, so that it outputs a test signal for fault criterion testing, namely, a switching quantity and an analog quantity.

[0097] In one embodiment, if Figure 16 As shown, the simulation computer 4 includes a script generation module 40 and a message analysis module 41;

[0098] The script generation module 40 is used to generate a fault criterion test script according to the fault information, disturbance information and power flow information of the fault criterion test model and feed it back to the real-time digital simulation device 1;

[0099] Specifically, the script generation module 40 generates a fault criterion test script that conforms to the script language of the real-time digital simulation device 1 based on the naming information of the control elements and monitoring elements of the model in the real-time digital simulation device 1. The fault criterion test script automatically traverses and tests multiple modes and types of faults based on the fault information, the disturbance information, and the power flow information. During the test, the fault criterion test script can be used to switch the fault logic. The fault criterion test script is used to set parameters and perform operation control in the runtime interface of the model operation software of the real-time digital simulation device 1, thereby realizing automatic start and stop of the model, automatic call of the power grid operation status, and automatic switching of fault types during the test.

[0100] The message analysis module 41 is used to check the result of the fault judgment test based on the fault information and the action message.

[0101] Specifically, the message analysis module 41 compares and verifies the fault information file at the same time with the action message file generated by the stabilization and control device 2 to determine whether the two match. If the two match, it means that the stabilization and control device 2 correctly identified the fault and the fault judgment test succeeded. If the two match, it means that the stabilization and control device 2 did not correctly identify the fault and the fault judgment test failed, requiring manual review of the stabilization and control device 2.

[0102] In one embodiment, the message analysis module 41 is specifically configured to:

[0103] extracting a fault type from the fault information and an action report from the action message;

[0104] Specifically, the message analysis module 41 verifies the results of the fault judgment test based on the fault information and action messages at the time of the fault. The action message is generated by the stabilization and control device 2 at the time of the fault and automatically uploaded to the centralized stabilization and control management system 3. It contains the site's action report and the time of the fault. The message analysis module 41 extracts the fault type from the fault information and the action report from the action message for the same period based on the time of the fault.

[0105] Confirm whether the fault in the action report during the same period is consistent with the fault type.

[0106] Specifically, the message analysis module 41 compares the fault type in the fault information at the same moment with the action report in the action message to determine whether the fault in the action report matches the fault type. If the two match, it means that the stabilization control device 2 correctly identified the fault and the fault judgment test succeeded. If the two match, it means that the stabilization control device 2 did not correctly identify the fault and the fault judgment test failed, requiring manual review of the stabilization control device 2.

[0107] For example, Figure 13 As shown, the fault information and action message are stored as CSV files. If the fault type in the fault information file is a single permanent fault, the keyword "single permanent" is automatically searched under the action message file at the same time. If the relevant keyword is successfully matched, the fault is correctly identified. If not matched, an alarm message is output.

[0108] In one embodiment, the fault judgment test system of the stabilization control device also includes: a power system synchronization clock device 5 connected to the simulation computer 4 and the multiple stabilization control devices 2, for sending a timing signal to the simulation computer 4 and the multiple stabilization control devices 2.

[0109] Specifically, the power system synchronous clock device 5 is respectively connected to several stabilization and control devices 2 to be tested and the simulation computer 4, and uses the time signals of the corresponding satellites obtained by the GPS antenna and the BD antenna to input clock signals to the several stabilization and control devices 2 to be tested and the simulation computer 4, which can ensure the consistency between the fault triggering time and the action message generation time.

[0110] like Figure 14 As shown, the automatic test process of the fault judgment criterion of the stabilization control device using the fault judgment criterion test system of the stabilization control device is as follows:

[0111] (1) Execute the fault judgment test script in the runtime interface of the model operation software of the real-time digital simulation device, call the start function to start the fault judgment test model, call the slider function to initialize the test-related time constants, which include reclosing time, fault tripping time and no-fault tripping time, etc.; call the switch function to set the switch variable to determine whether the disturbance is superimposed in the test fault entry.

[0112] (2) After the model is started, the suspend function command is called to suspend the execution of the fault judgment test script, and a fixed delay time is set (the delay time is greater than 5 seconds of a startup cycle time of the stabilization device) to ensure that the fault judgment test model of the real-time digital simulation equipment and the stabilization device are restored to normal operating status before the next step triggers the fault.

[0113] (3) Call the switch function to set the fault type, including switch a: fault trip / no fault trip, switch b: instantaneous fault / permanent fault, switch c: reclosing required / no reclosing required; call the setdial function to set the fault phase sequence; call the pushButton function to trigger the set fault.

[0114] (4) After the fault is triggered, the sprintf function, fprintf function, and saveplottocsv function are automatically called to save the fault recording, the fault type at the current fault moment, and other data to the local computer; after the stabilization and control device is activated according to the test signal, the action message is automatically uploaded to the stabilization and control centralized management system.

[0115] (5) Fault recovery: automatically calling the initial operating status information through the fault judgment test script.

[0116] (6) Call the if function command to determine whether all test items in the test item list have been executed. If they have been completed, proceed to the next step; otherwise, complete the setting of the next fault type to be tested in the fault set through the script and repeat the above steps 2-5.

[0117] (7) After all faults under the current flow mode have been tested, the if function command is called to determine whether all fault test items under the flow mode have been completed. If all have been completed, the stop function is called to shut down the model. Otherwise, the slider function command is called to automatically adjust the unit output and load size in the flow module to the new operating mode. Repeat steps 2-6 above until the stabilization control device completes the traversal test of all fault types under all flow modes.

[0118] (8) Through the message analysis module, the tripping information keywords (single-phase instantaneous fault, single-phase permanent fault, phase-to-phase short circuit fault and no-fault trip) in the action message at the same time are analyzed and compared with the fault type recorded at the same time. If the two are consistent, it means that the stabilization control device can correctly identify the specific fault type in this fault scenario; if they are inconsistent, further analysis and verification of the relevant stabilization control device is required.

[0119] The fault judgment test system for the stabilization control device provided in the present application is used to provide a fault judgment test model through a real-time digital simulation device, and output switch quantities and analog quantities according to the received fault judgment test script; multiple stabilization control devices are connected to the real-time digital simulation device through a sampling board card, and are used to generate action messages according to the switch quantities and analog quantities; a centralized stabilization control management system is connected to the multiple stabilization control devices through a first networking switch, and is used to receive action messages automatically uploaded by the multiple stabilization control devices and send the action messages to a simulation computer; a simulation computer is connected to the real-time digital simulation device and connected to the centralized stabilization control management system through a second networking switch, and is used to generate the fault judgment test script according to the fault judgment test model, and verify the results of the fault judgment test according to the received fault information and the action message, thereby realizing automatic traversal testing of the fault judgment of the stabilization control device and verifying the test results, thereby improving test efficiency and application value. By outputting switching quantities and analog quantities according to the fault judgment test script and generating action messages based on the switching quantities and analog quantities, fault judgment of multiple plants and components is realized; by generating fault judgment test scripts, automatic traversal testing of multiple modes and types of faults is realized; by performing fault judgment test based on fault information and action messages, automatic verification of test results is realized.

[0153] The following uses the simulation computer as the execution body to explain each step in detail.

[0154] S701: Generate a fault criterion test script based on the received fault information, disturbance information, and power flow information of the fault criterion test model and feed it back to the real-time digital simulation device; the fault information is generated by the real-time digital simulation device based on the acquired fault type; the disturbance information is generated by the real-time digital simulation device based on the acquired external disturbance amount; and the power flow information is generated by the real-time digital simulation device based on the acquired power flow mode;

[0155] Specifically, the script generation module of the simulation computer generates a fault criterion test script that conforms to the script language of the real-time digital simulation device based on the naming information of the control elements and monitoring elements of the model in the real-time digital simulation device. The fault criterion test script automatically traverses and tests multiple modes and types of faults based on the fault information, the disturbance information, and the power flow information. During the test, the fault criterion test script can be used to switch the fault logic. The fault criterion test script is used to set parameters and perform operation control in the runtime interface of the model operation software of the real-time digital simulation device 1, thereby realizing automatic start and stop of the model, automatic call of the power grid operation status, and automatic switching of fault types during the test.

[0156] S702: Receive an action message sent by the centralized stabilization and control management system; the action message is generated by the multiple stabilization and control devices based on switch quantities and analog quantities and automatically uploaded to the centralized stabilization and control management system; the switch quantities and analog quantities are output by the real-time digital simulation device based on the fault judgment criterion test script;

[0157] Specifically, the script generation module of the simulation computer generates a fault criterion test script based on the fault criterion test model, and then applies the various fault scenarios simulated by the fault criterion test script to the power grid model of the real-time digital simulation device, so that it outputs test signals for fault criterion testing, namely switching quantities and analog quantities.

[0158] The real-time digital simulation device connects to multiple stabilization and control devices via interface cards.

Analog quantities are transmitted via the GTAO interface card, while digital quantities are transmitted via the GTDO interface card. Analog quantities include voltage, current, and power, while digital quantities include switch position signals and protection trip signals. Based on the digital and analog quantities, the stabilization and control devices automatically generate action messages at the time of fault triggering and upload them to the centralized stabilization and control management system.

[0159] The action message automatically generated by the stabilization and control device at the time of fault triggering based on the switch quantity and analog quantity will be automatically uploaded to the centralized stabilization and control management system, and will be sent to the message analysis module by the centralized stabilization and control management system to verify the results of the fault judgment test, thereby realizing the centralized management of multiple stabilization and control devices.

[0164] Specifically, the simulation computer's message analysis module verifies the results of the fault judgment test based on the fault information and action messages at the time of the fault. Action messages are messages generated by the stabilization and control device at the time of the fault and automatically uploaded to the centralized stabilization and control management system. They contain the site's action report and the time of the fault. Based on the time of the fault, the simulation computer's message analysis module extracts the fault type from the fault information and the action report from the action message for the same period.

[0165] S802: Confirm whether the fault in the action report in the same period is consistent with the fault type.

[0166] Specifically, the simulation computer's message analysis module compares the fault type in the fault information at the same moment with the action report in the action message to determine whether the fault in the action report matches the fault type. If the two match, the stabilization control device correctly identified the fault and the fault judgment test succeeded. If the two match, the stabilization control device did not correctly identify the fault, the fault judgment test failed, and manual review of the stabilization control device is required.

[0167] For example, fault information and action messages are stored as CSV files. If the fault type in the fault information file is a single permanent fault, the keyword "single permanent" is automatically searched under the action message file at the same time. If the relevant keyword is successfully matched, the fault is correctly identified. If not matched, an alarm message is output.
