Description

Technical Field

[0001] The invention belongs to the field of energy consumption device valve control system testing, and in particular relates to a black module detection method and related equipment of an energy consumption device. Background Art

[0002] In the technical solution for integrating a large-capacity, long-distance offshore wind power DC system into the power grid, when a fault occurs on the inverter side, the grid-side voltage decreases, the power output of the inverter station decreases, and the energy of the offshore rectifier station remains unchanged. At this time, energy-consuming devices are mainly used to consume the unbalanced power in the system. The test topology diagram is shown in the figure below. Figure 1 The reliability of the energy consumption device function is directly related to the reliability of the system operation. If the power module of the energy consumption system has an uplink communication failure or fails to bypass the power module during the charging process, the energy consumption device may be damaged.

[0003] With the continuous advancement of flexible DC transmission technology, more new technologies have begun to be applied in the field of flexible DC transmission. For example, control systems and methods based on cross-connection of bypass control units of flexible DC converter valve power modules have begun to be applied in actual projects. However, in the traditional flexible DC valve control system, only monitoring can be performed between two adjacent power modules, and cross-bypass control cannot be achieved. Therefore, the existing black module detection method is not applicable to the flexible DC valve control system with cross-communication of sub-modules.

[0004] It can be seen that there is currently a lack of a black module identification measure for the bypass control unit cross-connected to the valve control system, which results in the inability to protect the valve control system in a timely manner, affecting the safe and stable operation of the system. Summary of the invention

[0005] The purpose of the present invention is to provide a black module detection method and related equipment for an energy-consuming device, so as to solve the technical problem that there is currently a lack of a black module identification measure for a bypass control unit cross-connected to a valve control system, resulting in the inability to timely protect the valve control system, affecting the safe and stable operation of the system.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: A black module detection method for an energy consumption device, comprising: Real-time collection of module fault information of the power module to be inspected and adjacent power modules; Based on the module fault information of the power module to be inspected and the adjacent power modules, a black module judgment is performed on the power module to be inspected. If the power module to be inspected is judged to be a black module, a protection instruction is output to lock the energy consumption device according to the protection instruction. When the module fault information collected from the power module to be inspected and the adjacent power modules are both uplink comprehensive fault information, it is determined that the power module to be inspected and the adjacent power modules are both black modules; When the module fault information collected of the power module to be inspected is uplink comprehensive fault information, and the module fault information of the adjacent power module is cross-communication fault information, a bypass instruction is sent to the energy consumption module control unit of the adjacent power module, so that the energy consumption module control unit of the adjacent power module controls the bypass control unit of the power module to be inspected according to the bypass instruction; if the bypass control unit of the power module to be inspected feeds back bypass unavailable information, the power module to be inspected is judged to be a black module.

[0007] Furthermore, the specific steps of collecting module fault information of the power module to be inspected and the adjacent power modules in real time include: The energy-consuming valve pulse distribution board monitors the power module to be inspected and the adjacent power modules in real time; The monitored module fault information to be judged is transmitted to the energy-consuming valve-controlled bridge arm control board, so that the valve-controlled bridge arm control board can make a comprehensive judgment on the module fault information to be judged, and output the module fault information of the power module to be tested and the adjacent power modules after judgment.

[0008] Furthermore, if the collected module fault information is direct communication fault information or cross communication fault information, the power module to be inspected corresponding to the module fault information is recorded in the historical fault module.

[0009] Furthermore, if the collected module fault information is downlink communication fault information or other communication fault information, the power module to be inspected corresponding to the module fault information is recorded in the historical fault module.

[0010] Furthermore, the other communication failures include high module voltage, low module voltage, IGCT drive failure, board power failure, energy extraction power failure and module control board power failure.

[0011] Furthermore, when the module fault information collected of the power module to be inspected is uplink comprehensive fault information, and the module fault information of the adjacent power module is cross-communication fault information, a bypass instruction is sent to the energy consumption module control unit of the adjacent power module, so that the energy consumption module control unit of the adjacent power module controls the bypass control unit of the power module to be inspected according to the bypass instruction; if the bypass control unit of the power module to be inspected feeds back bypass success information, the power module to be inspected is recorded in the historical fault module.

[0012] Furthermore, the energy consumption module control unit of the adjacent power module controls the bypass control unit of the power module to be inspected according to the bypass instruction, and the specific steps are as follows: The energy consumption module control unit of the adjacent power module controls the bypass control unit of the power module to be inspected according to the bypass instruction; The bypass control unit transmits a switch closing instruction to the bypass switch unit according to the bypass control instruction of the energy consumption module control unit of the adjacent power module to close the switch; If the switch is closed successfully, the bypass switch unit outputs bypass success information to the bypass control unit; otherwise, the bypass switch unit outputs bypass unavailable information to the bypass control unit.

[0013] A black module detection system for an energy consumption device, comprising: A fault information collection module is used to collect module fault information of the power module to be inspected and adjacent power modules in real time; A black module judgment module is used to judge whether the power module to be inspected is a black module based on the module fault information of the power module to be inspected and the adjacent power modules. If the power module to be inspected is judged to be a black module, a protection instruction is output to lock the energy consumption device according to the protection instruction. When the module fault information collected from the power module to be inspected and the adjacent power modules are both uplink comprehensive fault information, it is determined that the power module to be inspected and the adjacent power modules are both black modules; When the module fault information collected of the power module to be inspected is uplink comprehensive fault information, and the module fault information of the adjacent power module is cross-communication fault information, a bypass instruction is sent to the energy consumption module control unit of the adjacent power module, so that the energy consumption module control unit of the adjacent power module controls the bypass control unit of the power module to be inspected according to the bypass instruction; if the bypass control unit of the power module to be inspected feeds back bypass unavailable information, the power module to be inspected is judged to be a black module.

[0014] A device comprising: Memory for storing computer programs; The processor is used to implement the steps of the black module detection method of the energy consuming device when executing the computer program.

[0015] A computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the computer program is used to implement the steps of the black module detection method of the energy consumption device.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a black module detection method for an energy consumption device. The method collects module fault information of a power module to be detected and an adjacent power module in real time, and performs a black module judgment on the power module to be detected; if the power module to be detected is determined to be a black module, a protection instruction is output to realize the locking of the energy consumption device; when it is detected that the module fault information of the power module to be detected and its adjacent modules are both uplink comprehensive faults, that is, both direct connection and cross communication fail, it can be accurately judged that both are black modules; and when the module to be detected has an uplink comprehensive fault and the adjacent module has a cross communication fault, a bypass instruction is sent to the energy consumption module control unit of the adjacent module to control the bypass control unit of the module to be detected, and if the feedback bypass is unavailable, the module to be detected is determined to be a black module. The use of this method not only realizes the accurate discrimination of black modules, but also can take bypass control measures in time when a fault is found, effectively improving the safety stability and protection response speed of the valve control system.

[0017] Preferably, in the present invention, an energy-consuming valve pulse distribution board is used to perform real-time monitoring of the power module to be inspected and the adjacent power modules, and the monitoring information is transmitted to the energy-consuming valve-controlled bridge arm control board for comprehensive judgment, thereby improving the efficiency and accuracy of fault information collection and providing reliable data support for subsequent black module judgment.

[0018] Preferably, in the present invention, if the collected module fault information is direct communication fault information or cross communication fault information, the power module to be inspected corresponding to the module fault information is recorded in the historical fault module, which can identify the power module with historical fault characteristics, and help to repair or replace the faulty module in time to avoid the expansion of the fault.

[0019] Preferably, in the present invention, if the collected module fault information is downlink communication fault information or other communication fault information, the power module to be inspected corresponding to the module fault information is recorded in the historical fault module, so that more types of communication faults can be detected and processed in time, thereby improving the overall reliability and stability of the energy-consuming device.

[0020] Preferably, in the present invention, by judging the module fault information of the power module to be inspected and its adjacent modules, accurate identification and processing of complex fault conditions are achieved; when an uplink comprehensive fault occurs in the module to be inspected and a cross-communication fault occurs in the adjacent module, a bypass instruction is sent to the adjacent module to bypass the module to be inspected. If the bypass is successful, it is recorded in the historical fault module. If the bypass fails, it is judged as a black module. The use of this method is both accurate and efficient.

[0021] Preferably, in the present invention, the specific implementation process of bypass control includes the steps of an adjacent module energy consumption module control unit sending a bypass instruction, a bypass control unit of the module to be tested receiving the instruction and transmitting a switch closing instruction to the bypass switch unit, and the bypass switch unit feeding back bypass availability or unavailability information; this process can ensure that in the event of a fault, it can be quickly and accurately detected whether the power module to be tested is a black module, and timely measures can be taken to protect the energy consumption device.

DETAILED DESCRIPTION

[0023] Example 1 As described in the background technology, with the continuous advancement of flexible direct current transmission technology, more new technologies have begun to be applied to the field of flexible direct current transmission. A control system and method based on the cross-connection of bypass control units of flexible direct current converter valve power modules have begun to be applied in actual projects, and the traditional black module detection method is no longer applicable; for example, the existing method for detecting black modules in the flexible direct current valve control system with cross-communication of sub-modules can only realize the judgment of "uplink communication failure" or "bypass refusal to operate failure" of the module. It can be seen that with the development of flexible direct current transmission systems, the existing black module detection method is no longer suitable for the control system of cross-connection of bypass control units of power modules of energy-consuming devices currently being studied, and cannot meet the needs of the project; therefore, it is necessary to propose a new black module detection method and test system, which can be applied to energy-consuming devices with cross-connection of power module bypass control units, which is very necessary for the safe and stable operation of energy-consuming devices.

[0024] In order to achieve the above-mentioned purpose, the present invention provides a black module detection method for an energy-consuming device, which is suitable for a bypass control unit cross-connected valve control system. The black module can be identified during the full-link test, and the energy-consuming device can be locked in time through the black module protection tripping function, thereby protecting the energy-consuming device and ensuring the safe and stable operation of the system.

[0025] In order to facilitate understanding of the control method provided in this embodiment, the following terms are explained and illustrated: A black module refers to a power module that cannot communicate normally with the valve control device after charging, and whose status is unclear, or a power module that can establish a communication connection with the valve control but cannot be bypassed after reporting a power module failure and issuing a bypass command. Such power modules may be seriously damaged because their status cannot be determined or they cannot be turned on or off after being unlocked.

[0026] An upstream comprehensive fault means that both the upstream direct communication and the cross communication of the power module fail.

[0027] This embodiment provides a black module detection method for an energy consumption device, including: Real-time collection of module fault information of the power module to be inspected and adjacent power modules; Based on the module fault information of the power module to be inspected and the adjacent power modules, a black module judgment is performed on the power module to be inspected. If the power module to be inspected is determined to be a black module, a protection instruction is output to lock the energy consumption device according to the protection instruction.

[0028] like Figure 3 As shown, the above steps specifically include: State 1: The pulse distribution board in the energy-consuming valve pulse distribution screen determines the upstream (or downstream) direct (or cross) communication failure of the connected module in real time under all states of the energy-consuming valve. When a power module has one of the upstream (or downstream) direct (or cross) communication failures, the power module can send the information of this module to the energy-consuming valve control bridge arm control board through the upstream (or downstream) cross (or direct) communication. At this time, the power module operates normally.

[0029] State 2: After the energy-consuming valve pulse distribution board detects the uplink direct communication failure of the connected module and the cross communication failure of the adjacent paired module of the module for 500us, the uplink comprehensive communication failure state is set, and then the pulse distribution board sends the judgment result to the energy-consuming valve control bridge arm control board. After receiving the energy-consuming valve control bridge arm control board in the energy-consuming valve control main control screen, it makes a comprehensive judgment on the uplink comprehensive (direct connection + cross) communication state of the received module under the energy-consuming valve control module comparison state. If the uplink comprehensive (direct connection + cross) communication state of the same module is judged to be abnormal, the module is judged to have an uplink comprehensive communication failure (direct connection + cross connection is completely disconnected). At this time, the energy-consuming valve control bridge arm control board will send a locking + bypass command to the module (continuously send), and send the bypass command to the bypass control unit of this module through the control unit of the adjacent module. At this time, if the bypass switch of the power module is closed normally, the power module is bypassed successfully, the power module is counted into the historical fault state, the module comparison is successful, and the system operates normally.

[0030] State three: The energy-consuming valve pulse distribution board detects the upstream direct communication failure of the connected module and the upstream cross-communication failure of the adjacent paired module of the module and sends it to the energy-consuming valve control bridge arm control board. The energy-consuming valve control bridge arm control board will send a lock + bypass instruction (continuously send) to the module through the control unit of the adjacent module. At this time, if the bypass control unit of this module receives the bypass switch closing instruction of this module sent by the energy-consuming valve control through the adjacent module control unit, and the bypass switch state sent to the bypass control unit by the bypass switch unit of this module is in the open state, the module control unit of the adjacent module determines that there is an upstream communication failure in the cross bypass optical fiber with the bypass control unit of this module, and the adjacent module determines that the bypass of this module is unavailable. In this case, the energy-consuming valve control bridge arm control board determines that this module is a black module, outputs the module comparison fault mark, continuously locks the energy-consuming valve, and sends the module comparison fault information.

[0031] State 4: The energy-consuming valve pulse distribution board detects an upstream comprehensive (direct connection + cross connection) communication failure in the connected module and an upstream comprehensive (direct connection + cross connection) communication failure in the adjacent paired module, and sends the module's fault information to the energy-consuming valve-controlled bridge arm control board. The energy-consuming valve-controlled bridge arm control board determines that this module and the adjacent power module are black modules, outputs a module comparison fault flag, continuously locks the energy-consuming valve, and sends the module for comparison fault information.

[0032] State 5: The energy-consuming valve pulse distribution board detects that the connected module has a downlink communication (direct connection + cross) failure or the module voltage is too high, the module voltage is too low, the IGCT drive failure, the board power failure, the energy extraction power failure, the module control board power failure and other module failures, and sends them to the energy-consuming valve-controlled bridge arm control board. The energy-consuming valve-controlled bridge arm control board will send a lock + bypass command to the module. Regardless of whether the power module is bypassed, the energy-consuming valve-controlled bridge arm control board will record the module as a historical fault module. At this time, the module comparison is successful and the system operates normally.

[0033] The black module detection method of the energy consumption device provided in this embodiment is specifically implemented and verified as follows, including: like Figure 2 As shown, for the power modules of the energy-consuming device with cross-communication of power modules, when the power module control unit 201 of the power module to be controlled 200 (energy consuming module 1) has an uplink communication failure and a cross-communication failure occurs with the power module control unit 301 of the adjacent module 300 (energy consuming module 2), the bypass control unit 202 of the power module to be controlled communicates with the power module control unit 301 of the auxiliary control power module through optical fiber, and the bypass command issued by the energy-consuming valve bridge arm control board is sent to the bypass control unit 202 of the current module through the power module control unit 301 of the adjacent module, thereby achieving the purpose of closing the bypass switch unit 203 of the current module through the bypass control unit of the adjacent module.

[0034] The energy consumption device has a total of 524 power modules. Each fiber distribution chassis and pulse distribution chassis is connected to 131 power modules. The power modules are connected to the fiber distribution screen in the order of 1-524. Then the odd-numbered power modules and even-numbered power modules are connected to different pulse distribution chassis separately. Then, the two interface CPU boards of the pulse distribution chassis send the aggregated data to the A and B systems of the valve control host respectively. In this way, the redundant configuration of the A and B systems improves the reliability of the system. Figure 5 As shown, Figure 5 This is the overall architecture diagram of the full-link simulation platform.

[0035] The fault setting interface in the background of the full-link simulation system can set the voltage of a single module in batches or individually, and simulate the uplink (downlink) communication failure of the power module, high module voltage, low module voltage, IGCT drive failure, board power failure, energy extraction power failure, module control board power failure and other information. Set the fault information of the power module in the background of the full-link simulation, and then send the fault information of the power module to the fiber distribution screen, and load the netlist file of the power module on the pulse distribution board of the fiber distribution chassis to simulate the action of the actual module. In this way, the action of the power module can be actually simulated without connecting the actual power module to the energy-consuming valve control system. Then the action information of the power module is summarized and sent to the pulse distribution chassis, and sent to the valve control host chassis through the redundant link.

[0036] like Figure 4 As shown, in the energy consumption device locking mode, the fault state of the power module is simulated on the full-link simulation platform, and the AC incoming line switch of the flexible direct current valve control system is closed. When the average voltage of the energy consumption module is greater than 600V (0.3PU), the energy consumption device valve control system enters the uncontrolled charging state, and sends a reset command to all power modules after a delay of 10s for 100ms, and the energy consumption device enters the module comparison state. In the module comparison state, the pulse distribution chassis summarizes the fault information of the power module and sends it to the bridge arm control board of the valve group control chassis. The module comparison state lasts for 5ms; in the module comparison state, if the energy consumption valve group control board detects that there is a black module in the system that meets the corresponding logic, the bridge arm control board determines it as a black module, outputs the module comparison fault mark, continuously locks the energy consumption valve, and sends the module comparison fault information. If there is no black module in the system, the module comparison completion information is output, the system uncontrolled charging is completed, and enters the controllable charging state.

[0037] The detailed steps for judging the black module protection test are as follows: Step 1: In the locking stage of the energy-consuming device, the uplink communication failure of this module is simulated in the full-link simulation background. After the main control CPU board sends the module comparison command, this module sends the uplink direct communication failure to the energy-consuming control board. This module can send the status of this module to the background by communicating with the adjacent modules. At this time, this module operates normally.

[0038] Step 2: During the locking stage of the energy-consuming device, the control board power failure of this module is simulated in the full-link simulation background. After the valve control CPU board sends the module comparison command, this module reports the control board power failure. This module sends a bypass application to the valve control system. The energy-consuming control board sends locking and bypass instructions to the module. After the module is bypassed, it reports the uplink comprehensive fault. At this time, it is determined that the module is not a black module, the module comparison passes, and the module is counted into the historical fault module.

[0039] Step 3: During the locking stage of the energy-consuming device, the uplink communication failure and cross-communication failure of this module are simulated in the full-link simulation background. After the valve control CPU board sends the module comparison command, the energy consumption control board reports the uplink comprehensive communication failure of this module. At the same time, the energy consumption control board sends bypass and locking commands to this module through the bypass switch control board of the adjacent module. The bypass switch of this module is closed. At this time, the module comparison passes, and the module is counted into the historical fault state.

[0040] Step 4: During the blocking stage of the energy-consuming device, the uplink communication failure, cross-communication failure and bypass refusal failure of this module are simulated in the full-link simulation background. After the valve control CPU board sends the module comparison command, the energy consumption control board reports the uplink comprehensive communication failure and refusal failure of this module. At the same time, the module control board of the adjacent module determines that the cross bypass optical fiber with the bypass switch driver board of this module has an uplink communication failure, and the adjacent module reports that the bypass of this module is unavailable. At this time, the energy consumption control board determines that this module is a black module, outputs the module comparison failure flag, continuously blocks the energy consumption valve, and sends the module comparison failure information.

[0041] Step 5: During the locking stage of the energy-consuming device, the uplink communication and cross-communication failures of this module and the uplink communication and cross-communication failures of the adjacent modules are simulated in the full-link simulation background. After the valve control CPU board sends the module comparison command, the energy consumption control board reports the uplink comprehensive communication failure of this module and the uplink comprehensive communication failure of the adjacent module. The energy consumption control board determines that these two modules are black modules, outputs the module comparison fault flag, continuously locks the energy-consuming valve, and sends the module comparison fault information.

[0042] The key points of the black module detection method for the energy-consuming device provided in this embodiment are: proposing a black module detection method for the energy-consuming device based on the cross-connection of the bypass control unit of the power module, and using the full-link simulation platform of the energy-consuming device to simulate various fault states of the module, using the netlist file to simulate the fault conditions of the actual module, verifying the action of the energy-consuming valve control system and the correctness of the black module detection method, thereby improving the reliability and safety of the operation of the energy-consuming device.

[0043] It can be seen that for the energy-consuming device with cross-communication between adjacent modules (the bypass control unit cross-connects the valve control system), in the case of a module uplink comprehensive fault (both the uplink communication and the cross-communication of this module fail), the energy-consuming control board can send bypass and locking instructions to the adjacent modules, which are sent to the bypass control unit of this module through the power module control unit of the adjacent module, thereby achieving the purpose of closing the bypass switch of this module through the bypass control unit of the adjacent module; in this way, the power module is no longer judged as a black module when it only reports an uplink comprehensive fault (uplink + cross-fault), but is judged as a black module when an uplink comprehensive fault occurs in this module and the adjacent module reports that the bypass of this module is unavailable, or when both this module and the adjacent module have an uplink comprehensive fault, thereby improving the stability and reliability of the system.

[0044] Example 2 like Figure 6 As shown, this embodiment provides a black module detection method for an energy consumption device, comprising the following steps: Real-time collection of module fault information of the power module to be inspected and adjacent power modules. The specific steps include: The energy-consuming valve pulse distribution board monitors the power module to be inspected and the adjacent power modules in real time; The monitored module fault information to be judged is transmitted to the energy-consuming valve-controlled bridge arm control board, so that the valve-controlled bridge arm control board can make a comprehensive judgment on the module fault information to be judged, and output the module fault information of the power module to be tested and the adjacent power modules after judgment.

[0045] Based on the module fault information of the power module to be inspected and the adjacent power modules, a black module judgment is performed on the power module to be inspected. If the power module to be inspected is judged to be a black module, a protection instruction is output to lock the energy consumption device according to the protection instruction. When the module fault information collected from the power module to be inspected and the adjacent power modules are both uplink comprehensive fault information, it is determined that the power module to be inspected and the adjacent power modules are both black modules; When the module fault information collected of the power module to be inspected is the uplink comprehensive fault information, and the module fault information of the adjacent power module is the cross-communication fault information, a bypass instruction is sent to the energy consumption module control unit of the adjacent power module, so that the energy consumption module control unit of the adjacent power module controls the bypass control unit of the power module to be inspected according to the bypass instruction; if the bypass control unit of the power module to be inspected feeds back bypass unavailable information, the power module to be inspected is judged to be a black module; Alternatively, if the collected module fault information is direct communication fault information or cross communication fault information, the power module to be inspected corresponding to the module fault information is recorded in the historical fault module.

[0046] Alternatively, if the collected module fault information is downlink communication fault information or other communication fault information, the power module to be inspected corresponding to the module fault information is recorded in the historical fault module. Among them, other communication faults include high module voltage, low module voltage, IGCT drive fault, board power fault, energy extraction power fault and module control board power fault.

[0047] Alternatively, when the module fault information collected of the power module to be inspected is uplink comprehensive fault information, and the module fault information of the adjacent power module is cross-communication fault information, a bypass instruction is sent to the energy consumption module control unit of the adjacent power module, so that the energy consumption module control unit of the adjacent power module controls the bypass control unit of the power module to be inspected according to the bypass instruction; if the bypass control unit of the power module to be inspected feeds back bypass success information, the power module to be inspected is recorded as a historical fault module, and the specific steps are as follows: The energy consumption module control unit of the adjacent power module controls the bypass control unit of the power module to be inspected according to the bypass instruction; The bypass control unit transmits a switch closing instruction to the bypass switch unit according to the bypass control instruction of the energy consumption module control unit of the adjacent power module to close the switch; If the switch is closed successfully, the bypass switch unit outputs bypass success information to the bypass control unit; otherwise, the bypass switch unit outputs bypass unavailable information to the bypass control unit.

[0048] like Figure 7 As shown, the present embodiment further provides a black module detection system for an energy consumption device, comprising: a fault information collection module, for collecting module fault information of a power module to be detected and an adjacent power module in real time; a black module judgment module, for performing a black module judgment on the power module to be detected based on the module fault information of the power module to be detected and the adjacent power module, and if the power module to be detected is determined to be a black module, a protection instruction is output to lock the energy consumption device according to the protection instruction; wherein, when the module fault information collected of the power module to be detected and the adjacent power module are both uplink comprehensive fault information, it is determined that the power module to be detected and the adjacent power module are both black modules; when the module fault information collected of the power module to be detected is uplink comprehensive fault information, and the module fault information of the adjacent power module is cross-communication fault information, a bypass instruction is sent to the energy consumption module control unit of the adjacent power module, so that the energy consumption module control unit of the adjacent power module controls the bypass control unit of the power module to be detected according to the bypass instruction; if the bypass control unit of the power module to be detected feeds back bypass unavailable information, the power module to be detected is determined to be a black module.

[0049] The present invention also provides a device, comprising: a memory for storing a computer program; and a processor for implementing the steps of the black module detection method of the energy consuming device when executing the computer program.
