Description

Technical Field

[0001] This invention patent application belongs to the technical field of power electronic equipment detection, and particularly relates to a power unit automatic maintenance test device, its test method and system. Background Art

[0002] In recent years, with the development of power electronic technology, advanced high-voltage transmission technologies such as SVG reactive power compensation devices, MMC flexible DC converter valves, high-voltage DC circuit breakers, and low-frequency power transmission frequency conversion valves have been widely used. These devices utilize large-scale power electronic power unit cascading technology to effectively solve the problems of flexible control and regulation of high-voltage grid systems. Flexible DC converter valves, DC circuit breakers, low-frequency power transmission frequency conversion valves, etc. are all composed of cascading multiple power electronic power units with the same structure, and have characteristics such as high intelligence and high integration. The number of power electronic power units varies with the voltage level of the converter station / frequency conversion station. With the development of power transmission devices such as flexible DC transmission, DC circuit breakers, and low-frequency power transmission, the voltage level of the converter station / frequency conversion station shows an upward trend, and the cascading number of power electronic power units also increases significantly.

[0003] The maintenance tests of devices such as MMC flexible DC converter valves, high-voltage DC circuit breakers, and low-frequency power transmission frequency conversion valves are usually carried out in units of single valve modules or single power units. A single valve module usually consists of several power units.

[0004] The existing valve module or power unit maintenance tests are composed of a remote monitoring and control platform outside the valve hall (used to detect and output the status or data of the valve module or power unit under test), a controllable high-voltage power supply inside the valve hall (used to supply power to the valve module or power unit under test), a circuit breaker (used to control the on-off between the controllable high-voltage power supply and the power supply of the valve module or power unit under test), optical fibers, wires, etc. It is necessary to manually connect and build the test platform required for maintenance tests for each component. The entire maintenance test process has many steps and is cumbersome, with low automation and integration levels. If the operation sequence is incorrect during the maintenance test, it will cause damage to the maintenance test device or power unit. Especially in the case of power unit triggering, if the circuit breaker fails to be disconnected in time, it will cause damage to equipment such as the power supply, resulting in large economic losses and even personal injuries. In addition, the existing maintenance test process requires the joint cooperation of the remote monitoring and control platform outside the valve hall and the test platform body inside the valve hall. There are problems with more working surfaces in the maintenance test, such as poor communication between the staff of the remote monitoring and control platform and the staff of the test platform body. However, with the increase in the number of cascaded power units, the valve hall site is getting larger and larger, and the distance between the valve hall and the remote monitoring and control platform is getting farther and farther. The long-distance operation and cooperation greatly reduce the work efficiency of the maintenance test, and the labor cost of the maintenance work is extremely high. Summary of the Invention

[0068] The following further details the specific embodiments of the present invention patent application with reference to the accompanying drawings.

[0069] Embodiment 1:

[0070] The present invention patent application provides a power unit automatic maintenance and testing device, as Figure 1As shown in the figure, it includes: a controllable high-voltage power supply, a circuit breaker, and a controller located in the valve hall;

[0071] The controller is respectively communicatively connected to the controllable high-voltage power supply and the circuit breaker, and the controller is communicatively connected to a monitoring and control platform located outside the valve hall; the controllable high-voltage power supply is electrically connected to the object to be measured through the circuit breaker;

[0072] The controller is used to control the opening and closing of the circuit breaker to control the connection state between the controllable high-voltage power supply and the object to be measured; it is also used to control the monitoring and control platform to trigger the object to be measured and receive the test state of the object to be measured sent by the monitoring and control platform; wherein, the monitoring and control platform is communicatively connected to the object to be measured.

[0073] In this invention patent application, the controller includes: an industrial computer and a control board; the control board is connected to the controllable high-voltage power supply, the circuit breaker, and the industrial computer;

[0074] The industrial computer is used to send control signals to the control board; it is also used to send instructions to the monitoring and control platform to trigger the object to be measured;

[0075] The control board is used to control the opening and closing of the circuit breaker according to the control signal to control the connection state between the controllable high-voltage power supply and the object to be measured, and receive the test state of the object to be measured sent by the monitoring and control platform.

[0076] Meanwhile, the device further includes a switch; the switch is respectively communicatively connected to the monitoring and control platform and the controller; the switch is used to forward the test state of the object to be measured sent by the monitoring and control platform to the controller, and is also used to forward the instruction to the monitoring and control platform.

[0077] A specific example of a power unit automatic maintenance and test device proposed in this invention patent application, such as Figure 2 As shown in the figure, it integrates components such as a switch, a host computer / industrial computer, a controllable high-voltage power supply, a circuit breaker, and a control board. The switch inside the maintenance and test device is respectively connected to the internal host computer / industrial computer and the control board through network cables. The host computer connects to the control board through the switch to control the circuit breaker and the controllable high-voltage power supply inside the device, and the device is connected to the valve module or power unit to be measured outside the device through high-voltage output lines. The switch, host computer / industrial computer, controllable high-voltage power supply, control board, and circuit breaker in the maintenance and test device connect the external monitoring and control platform and the object to be measured (the object to be measured is the valve module or power unit to be measured) as a whole.

[0078] The device is connected to the control cabinet of the remote monitoring and control platform through optical fiber, and the device is connected to the object under test through high-voltage wires. The switch and the host computer / industrial computer are connected through network cables inside the maintenance test device, the switch and the control board are connected through optical fiber, the host computer / industrial computer and the control board are connected through the serial port, and the control board is connected to the circuit breaker and the controllable high-voltage power supply through control lines. The host computer operates the controllable high-voltage power supply and circuit breaker through the control board; the switch remotely communicates with the monitoring and control platform to control the valve module or power unit under test.

[0079] The maintenance and testing device proposed in the patent application of the present invention is designed as a trolley type. According to the position of the valve module or power unit to be tested, the position of the maintenance and testing device can be flexibly adjusted to carry out maintenance and testing work efficiently and conveniently.

[0080] A fiber optic interface card is added to the control cabinet of the monitoring and control platform. The switch of the maintenance and testing device is connected to the fiber optic interface card of the monitoring and control platform through optical fiber. The monitoring and control platform issues an enable / disable command to allow / prohibit the maintenance and testing device from controlling the valve module or power unit. In this way, the control of the object under test is transferred from the remote monitoring and control platform to the valve hall, and the object under test (the object under test is the valve module or power unit under test) is directly controlled by the maintenance and testing device in the valve hall.

[0081] After the maintenance is completed, remove the optical fiber connected to the monitoring and control platform on the maintenance test device, and disconnect the high-voltage connection line between the maintenance test device and the valve module or power unit under test. The communication optical fiber is stored in the optical fiber slot under the valve tower for subsequent maintenance.

[0082] The device provided in the patent application of the present invention has a highly integrated design and a portable design, which eliminates the need for temporary arrangement of various components and wiring to build a platform for the original valve hall maintenance test. The platform construction can be completed by simply connecting the high-voltage output line of the maintenance and testing device to the valve module or power unit under test. At the same time, it is convenient for the implementation of testing work in the valve hall, eliminating the need for on-site operators to repeatedly build and dismantle the test platform and move it to the position of the object under test due to the different positions of the valve module or power unit under test. Instead, they only need to move the test device trolley to the position of the object under test, which greatly improves the efficiency of on-site work.

[0083] Meanwhile, by using the device proposed in this invention patent application, the entire maintenance and testing process will be made streamlined and automated. All maintenance and testing work can be carried out inside the valve hall, eliminating the need for coordinated operations between the remote monitoring and control platform and the valve hall. The circuit breaker, controllable high-voltage power supply, and the control of valve modules or power units are automatically operated through the maintenance and testing device. This effectively avoids misoperations caused by improper human communication and resulting problems in the operation sequence during past maintenance; enhances the safety of maintenance and testing work, fully safeguarding the safety of equipment and the personal safety of staff; meanwhile, it can reduce the number of on-site staff, improve on-site work efficiency, and reduce maintenance costs.

[0084] In summary, the key points of this invention patent application lie in the integration of components for maintenance and testing, the programming and automation of maintenance and testing steps, the integration of the maintenance work surface, and the portable design of the maintenance device, optimizing the on-site maintenance and testing process and improving the safety and work efficiency of maintenance and testing. The device proposed in this invention patent application is connected to the remote monitoring and control platform through optical fibers. The remote monitoring and control platform issues enable / disable commands to allow / forbid the control of the maintenance and testing device over the valve module or power unit under test, transferring the work content of the remote monitoring and control platform during the maintenance and testing process to the valve hall for easier on-site operation coordination, reducing on-site maintenance operators, improving maintenance work efficiency, and reducing maintenance costs. This invention patent application proposes an integrated design of the components required for maintenance and testing inside the maintenance and testing device and a portable design of the maintenance and testing device, reducing the workload of valve hall maintenance and testing, reducing on-site maintenance operators, improving maintenance work efficiency, and reducing maintenance costs.

[0085] Embodiment 2:

[0086] Based on the same inventive concept, this invention patent application provides an automated maintenance and testing method for power units, as Figure 3 shown, including the following steps:

[0087] Step 1: The controller controls the opening and closing of the circuit breaker to control the connection state of the controllable high-voltage power supply and the object under test;

[0088] Step 2: The controller controls the monitoring and control platform to trigger the object under test and receives the test status of the object under test sent by the monitoring and control platform. If the test status of the object under test is normal, the detection ends; otherwise, it outputs that the test is unqualified.

[0089] The controller, circuit breaker, controllable high-voltage power supply, and monitoring and control platform all belong to the above-mentioned device.

If the output voltage waveform of the object under test is consistent with the standard waveform and there is no fault alarm, then the consistency between the output voltage waveform of the object under test and the standard waveform is normal, and it proceeds to the next step; otherwise, it outputs that the test is unqualified.

[0098] ※ The controller receives whether the object under test reports an undervoltage fault and performs a fault bypass operation sent by the monitoring and control platform. If the object under test reports an undervoltage fault and performs a fault bypass operation, then the accuracy of the object under test reporting an undervoltage fault and performing a fault bypass operation is normal, and it proceeds to the next step; otherwise, it outputs that the test is unqualified.

[0099] Among them, the initial state of the object under test includes: the correctness of the communication voltage range of the object under test, the correctness of the program version number of the object under test, and the effectiveness of the status report of the object under test.

[0100] Therefore, the controller controls the monitoring and control platform to trigger the object under test, accepts the initial state of the object under test sent by the monitoring and control platform, and enters the next step if the initial state of the object under test is normal; otherwise, it outputs that the test is unqualified, including:

[0101] ※ The controller controls the monitoring and control platform to trigger the object under test, receives whether the object under test has established communication with the monitoring and control platform sent by the monitoring and control platform, and receives the voltage value of the object under test sent by the monitoring and control platform and judges whether it reaches the predetermined value. If it reaches the predetermined value, the communication voltage range of the object under test is correct, and it enters the next step; otherwise, it outputs that the test is unqualified.

[0102] ※ The controller receives the program version number reported by the object under test sent by the monitoring and control platform and judges whether it meets the preset standard of the controller.

[0107] ※ The controller controls the monitoring and control platform to issue a running instruction and receives the status report of the object under test sent by the monitoring and control platform.

[0108] In this invention patent application, during the entire testing process, the circuit breaker needs to be opened and closed multiple times, and charged to different voltages multiple times to perform different operations on the valve module or power unit under test and determine the test results. The method proposed in this invention patent application can achieve that all the above operations are realized by an automated program. The host computer / industrial control computer automatically performs status detection, control, and test determination on the valve module or power unit under test according to the set program, without the need for on-site operators to perform complicated operations. Only the valve module or power unit after testing needs to be repaired according to the test results, which greatly reduces the work complexity of on-site operators and greatly improves the on-site work efficiency.

[0109] This invention patent application judges the opening and closing state of the circuit breaker, the output value and output state of the controllable high-voltage power supply, and the sub-module information reported by the valve module or power unit under test to the monitoring and control platform through the host computer / industrial control computer, and makes real-time judgments according to the actual progress of the steps to determine the execution situation of the maintenance test device and the test state of the object under test. As Figure 4 shown, the specific steps are as follows:

[0110] 1) After confirming that the electrical wiring between the maintenance test device and the valve module or power unit under test is completed, click the "Automatic Test" start button on the interface of the host computer / industrial control computer of the maintenance test device to start the automated maintenance test operation with one key.

[0111] 2) The host computer / industrial control computer automatically issues a command to close the circuit breaker and waits for the feedback of the circuit breaker status; if the circuit breaker feedbacks that the closing is successful, proceed to the next step; if the circuit breaker does not feedback that the closing is successful, it is determined that there is a fault in the maintenance device, the automated detection is stopped, and "Detection Device Fault" is reported.

[0112] 3) The host computer / industrial control computer automatically sets the output value of the controllable high-voltage power supply and issues a voltage output command; the host computer monitors the voltage output situation of the controllable high-voltage power supply; if the output voltage of the power supply meets the set value and output state requirements, proceed to the next step; if the high-voltage power supply has no output or the output voltage deviates from the set value by a certain range, it is determined that there is a fault in the maintenance device, the automated detection is stopped, and "Detection Device Fault" is reported.

[0113] 4) The host computer / industrial control computer automatically judges whether the object under test is powered on and communication is established and charged to the preset voltage value; if the object under test establishes communication with the monitoring and control platform and the voltage value reported to the monitoring and control platform reaches the predetermined value ±25V, it is determined that the communication of the object under test is established and the power-on is successful, and proceed to the next step; otherwise, it is determined that the object under test is "test unqualified".

[0114] 5) The host computer / industrial control computer automatically judges the program version number reported by the object under test through the remote monitoring and control platform; if the program version number meets the preset standard of the host computer / industrial control computer, proceed to the next step; otherwise, it is determined that the object under test is "test unqualified".

[0115] 6) The host computer / industrial control computer automatically issues operation instructions through the remote monitoring and control platform, and checks the status report of the object under test to determine whether there is a fault alarm; if the object under test reports an available status, proceed to the next step; otherwise, determine that the object under test "failed the test".

[0116] 7) The host computer / industrial control computer automatically issues a command to disconnect the circuit breaker and waits for the feedback of the circuit breaker status; if the circuit breaker feedback indicates successful disconnection, proceed to the next step; if the circuit breaker does not feedback successful disconnection, determine that there is a fault in the maintenance device, stop the automatic detection, and report "detection device fault".

[0117] 8) The host computer / industrial control computer automatically issues a command to trigger the power device of the object under test through the remote monitoring and control platform. The host computer checks whether the output voltage waveform of the object under test is consistent with the standard waveform, and checks the status report of the object under test to determine whether there is a fault alarm; if the output voltage waveform of the object under test is consistent with the standard waveform and no fault alarm is reported, proceed to the next step; otherwise, determine that the object under test "failed the test".

[0118] 9) The host computer / industrial control computer waits for the object under test to unlock and discharge until the under-voltage protection action occurs. The host computer automatically detects through the remote monitoring and control platform whether the sub-module reports an under-voltage fault and the fault bypass action at the preset under-voltage protection setting value; if the sub-module under-voltage alarms and the bypass is executed, proceed to the next step; otherwise, determine that the object under test "failed the test".

[0119] 10) The host computer / industrial control computer automatically issues a command to close the circuit breaker and waits for the feedback of the circuit breaker status; if the circuit breaker feedback indicates successful closing, proceed to the next step; if the circuit breaker does not feedback successful closing, determine that there is a fault in the maintenance device, stop the automatic detection, and report "detection device fault".

[0120] 11) The host computer / industrial control computer automatically sets the output value of the controllable high-voltage power supply and issues a voltage output command; the host computer monitors the voltage output of the controllable high-voltage power supply; if the power supply output voltage meets the set value and output status requirements, proceed to the next step; if the high-voltage power supply has no output or the output voltage deviates from the set value by a certain range, determine that there is a fault in the maintenance device, stop the automatic detection, and report "detection device fault".

[0121] 12) The host computer / industrial control computer automatically determines whether the object under test is powered on, communication is established, and it is charged to the preset voltage value; if the object under test establishes communication with the monitoring and control platform and reports that the voltage value on the monitoring and control platform reaches the predetermined value ±25V, determine that the sub-module communication is established and powered on successfully, and proceed to the next step; otherwise, determine that the object under test "failed the test".

[0122] 13) The host computer automatically issues operation instructions through the remote monitoring and control platform, and checks the status reports of the objects under test to determine whether there are fault alarms. If the object under test reports an available status, it is determined that the object under test is "test qualified" and the next step is executed; otherwise, it is determined that the object under test is "test unqualified".

[0123] 14) The host computer / industrial control computer automatically issues a command to disconnect the circuit breaker and waits for the feedback of the circuit breaker status. If the circuit breaker feedbacks that the disconnection is successful, the next step is executed. If the circuit breaker does not feedback that the disconnection is successful, it is determined that there is a fault in the maintenance device, the automated detection is stopped, and "detection device fault" is reported.

[0124] 15) The host computer / industrial control computer automatically sets the output value of the controllable high-voltage power supply to zero and issues a voltage stop output command. The host computer monitors the voltage output of the controllable high-voltage power supply. If the power supply output voltage meets the set value and output status requirements, the next step is executed. If the high-voltage power supply has no output or the output voltage deviates from the set value by a certain range, it is determined that there is a fault in the maintenance device, the automated detection is stopped, and "detection device fault" is reported.

[0125] At this point, the automated test process of the maintenance test ends. After the on-site operator completes the discharging work of the object under test, the direct connection line between the maintenance test device and the object under test is removed, and a maintenance plan is formulated according to the maintenance test feedback information, and the subsequent work can be carried out.

[0126] After the maintenance is completed, the optical fiber connected to the monitoring and control platform on the maintenance test device is removed, and the high-voltage connection line between the maintenance test device and the valve module or power unit under test is disconnected. The communication optical fiber is stored in the optical fiber slot under the valve tower for convenient subsequent maintenance.

[0127] In summary, for the method proposed in this invention patent application, after the maintenance test device is wired, only one-key startup is required to complete the automatic opening and closing, charging and discharging, execution of detection items, and judgment of the execution status of each link. The operation process of the maintenance test is greatly reduced, human-induced misoperations during the maintenance test are avoided, and the safety of equipment and personnel is greatly guaranteed. For the method proposed in this invention patent application, the host computer / industrial control computer determines the execution status of the maintenance test device and the maintenance test status of the sub-module by real-time judgment of the opening and closing status of the circuit breaker, the output value and output status of the controllable high-voltage power supply, and the information reported by the object under test. The implementation of this strategy greatly reduces the operation process of the maintenance test, avoids human-induced misoperations during the maintenance test, and greatly guarantees the safety of equipment and personnel.
