Description

Technical Field

[0001] This invention relates to the field of power electronics technology, and specifically to a test device and test method for a converter valve control device of an energy router. Background Technology

[0002] With the widespread application of power electronics technology in power systems, people have higher requirements for power electronic equipment. As an important part of the power system's power transmission process, the energy router is used to undertake AC and DC conversion tasks at different voltage levels. It is usually composed of a topology consisting of a cascaded H-bridge, a high-voltage isolation stage, a high-frequency transformer, and a low-voltage isolation stage. Its efficiency and reliability are related to the economic and stable operation of the system.

[0003] Due to the unique topology of energy routers and the lack of a corresponding model in RTDS (Real Time Digital Simulation System), topologies are currently mostly built using discrete components. High-capacity energy routers used in engineering applications have a large number of topology layers, making it difficult to achieve full-scale modeling in real-time simulation equipment. This poses a challenge to the testing of energy router valve control devices, making it impossible to effectively test these devices, which poses a significant safety hazard for engineering applications. Summary of the Invention

[0004] In view of this, the present invention provides a testing device and testing method for a converter valve control device of an energy router, so as to solve the problem that the valve control device cannot be effectively tested because the valve control cannot be fully connected to RTDS.

[0005] In a first aspect, the present invention provides a test apparatus for a valve control device of an energy router converter valve. The test apparatus includes an RTDS real-time simulation device and a valve control test device. The RTDS real-time simulation device is configured with a first preset number of energy router converter valves at different levels, and the valve control test device is configured with a second preset number of energy router converter valves at different levels. The sum of the first preset number of levels and the second preset number of levels equals the total number of levels of the energy router converter valves.

[0006] Both the RTDS real-time simulation device and the valve control test device are connected to the energy router converter valve control device. The energy router converter valve control device analyzes and modulates the modulation wave and control signal sent by the energy router main control device, generates trigger commands, and sends a first trigger command corresponding to a first preset number of energy router converter valves to the RTDS real-time simulation device, and sends a second trigger command corresponding to a second preset number of energy router converter valves to the valve control test device. The trigger commands include both the first and second trigger commands. The RTDS real-time simulation device makes a corresponding simulation response based on the first trigger command; the valve control test device makes a corresponding simulation response based on the second trigger command.

[0007] By coordinating the valve control test device and the RTDS real-time simulation device, the trigger program test of the test device for the valve control device of the energy router converter valve was realized.

[0008] In one optional embodiment, the testing device further includes a communication module, one end of which is connected to the RTDS real-time simulation device, and the other end of which is connected to the valve control testing device. The RTDS real-time simulation device sends a preset signal that is simulated in real time to the valve control testing device through the communication module.

[0009] By setting up a communication module, it is ensured that each test board can maintain real-time communication with the RTDS real-time simulation device.

[0010] In one optional implementation, the RTDS real-time simulation device directly simulates the operating status of each sub-module of the energy router converter valve based on the first preset number of energy router converter valves, generates corresponding feedback information, and then sends it to the energy router monitoring device through the energy router converter valve control device.

[0011] In one optional implementation, the valve control test device generates a corresponding return status based on the return signal sent by the external controller, and generates corresponding return information based on the return status, and sends it to the energy router monitoring device through the energy router converter valve control device.

[0012] By coordinating the valve control test device and the RTDS real-time simulation device, the retesting procedure test of the test device for the valve control device of the energy router converter valve was realized.

[0013] In one optional embodiment, the valve-controlled testing device includes: at least one test board, a power module, and a display device, wherein,

[0014] Each test board has at least one built-in central control board program, which is used to make a corresponding simulated response according to the second trigger command;

[0015] The test board is also used to generate a corresponding return check status based on the return check signal sent by the external controller, and generate corresponding return check information based on the return check status, and send it to the energy router monitoring device through the energy router converter valve control device;

[0016] The display device is connected to the test board and is used to display the simulated response and return test status;

[0017] The power module is used to supply power to the test board.

[0018] In one alternative embodiment, the testing device further includes a switch, one end of which is connected to the other end of the communication module, and the other end of which is connected to each test board in the valve control testing device.

[0019] When real-time simulation testing is not required or high parameter accuracy is not critical, the switch can be turned off to perform testing using local data. When the testing device requires real-time parameters or high parameter accuracy is required, the switch can be turned on to perform testing using the communication module interface. Multiple testing modes are provided to the user through the switch settings.

[0020] In one optional implementation, the test board includes: a test control circuit, a return signal action circuit, and at least one trigger command detection circuit, wherein,

[0021] The test control circuit is connected to the valve control device of the energy router converter valve and is used to parse the received second trigger command to obtain at least one trigger command bit, and send the trigger command bit to the corresponding trigger command detection circuit in sequence.

[0022] The trigger command detection circuit is connected to the test control circuit and is used to simulate the converter valve module to make a corresponding simulated response to the received trigger command bit.

[0023] The return test signal action circuit is connected to the test control circuit and is used to generate a corresponding return test status based on the return test signal sent by the external controller, and send it to the test control circuit.

[0024] The test control circuit generates corresponding return inspection information based on the return inspection status and sends it back to the energy router converter valve control device.

[0025] In one alternative implementation, the trigger pulses of the converter valve module are connected to the RTDS real-time simulation device in the order of 1, 1+N, 1+2N...

[0026] Secondly, the present invention provides a test method for an energy router converter valve control device, based on the test device of the first aspect, the test method comprising:

[0027] The device receives a first trigger command from the energy router converter valve control device. The first trigger command is used to trigger the energy router converter valves of the first preset number of levels built by the RTDS real-time simulation device. The RTDS real-time simulation device makes a corresponding simulation response according to the first trigger command.

[0028] The device receives a second trigger command sent by the energy router converter valve control device. The second trigger command is used to trigger the energy router converter valves of the second preset number of levels built by the valve control test device. The valve control test device makes a corresponding simulated response according to the second trigger command.

[0029] By comparing the trigger commands and the corresponding simulated responses, it is determined whether the energy router converter valve control device, the central control board control program in the valve control test device, and the RTDS real-time simulation device are faulty.

[0030] In one optional implementation, the testing method further includes:

[0031] Generate the corresponding return check status based on the return check signal sent by the external controller;

[0032] Generate corresponding return inspection information based on the return inspection status;

[0033] The return inspection information is sent to the energy router monitoring device through the valve control device of the converter valve of the energy router.

[0034] By comparing the return inspection information and corresponding return inspection status displayed by the monitoring equipment, it is determined whether the energy router converter valve control device, the central control board control program in the valve control test device, and the RTDS real-time simulation device are faulty.

[0043] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] This invention provides a testing device for a converter valve control device in an energy router, applicable to scenarios involving simulation testing of multi-module valve control devices. For example... Figure 1 The test device for the energy router converter valve control device includes: an RTDS real-time simulation device 1 and a valve control test device 2. The RTDS real-time simulation device 1 is equipped with a first preset number of energy router converter valves, and the valve control test device 2 is equipped with a second preset number of energy router converter valves. The sum of the first and second preset number of levels equals the total number of levels of the energy router converter valves. Both the RTDS real-time simulation device 1 and the valve control test device 2 are connected to the energy router converter valve control device. The energy router converter valve control device analyzes and modulates the modulation wave and control signal sent by the energy router main control device, generates trigger commands, and sends the first trigger command corresponding to the first preset number of energy router converter valves to the RTDS real-time simulation device 1, and sends the second trigger command corresponding to the second preset number of energy router converter valves to the valve control test device 2. The trigger commands include the first trigger command and the second trigger command. The RTDS real-time simulation device 1 makes a corresponding simulated response based on the first trigger command. The valve control test device 2 makes a corresponding simulated response based on the second trigger command.

[0048] In one specific embodiment, due to the unique topology of energy routers and the lack of a corresponding model in RTDS, topologies are currently often built using discrete components. High-capacity energy routers used in engineering applications have numerous topology layers, making full-scale modeling difficult in real-time simulation equipment. This poses a challenge to testing the valve control devices of energy routers. For example, RTDS can only simulate four layers of the CHB-MAB structure of a flexible transformer, while the actual device requires simulating twelve layers. This means that RTDS can only simulate the converter valves at layers 1, 4, 7, and 10, making it impossible to effectively test the valve control devices.

[0049] Therefore, in this embodiment of the invention, the testing of the valve control device of the power router converter valve is realized through the coordinated cooperation of the valve control test device 2 and the RTDS real-time simulation device 1. Specifically, the RTDS real-time simulation device 1 sends the feedback signals required for valve control in layers 1, 4, 7, and 10 (such as module capacitor voltage, bridge arm current, fault information, etc.) and receives the trigger pulse signal for valve control. Then, the valve control test device 2 sends the feedback signals of the remaining layers, so that the two devices jointly complete the simulation test of the multi-topology structure.

[0050] Furthermore, by comparing the simulated response of the RTDS real-time simulation device 1 and the valve control test device 2 with their corresponding modulation waves, users can determine whether the energy router converter valve control device, the central control board control program in the valve control test device 2, and the RTDS real-time simulation device 1 are faulty.

[0051] In one alternative implementation, such as Figure 1 As shown, the testing device also includes a communication module 3. One end of the communication module 3 is connected to the RTDS real-time simulation device 1, and the other end of the communication module 3 is connected to the valve control testing device 2. The RTDS real-time simulation device 1 sends the preset signal simulated in real time to the valve control testing device 2 through the communication module 3.

[0052] In one specific embodiment, such as Figure 2 As shown, one end of the communication module 3 is connected to the RTDS real-time simulation device 1, and the other end of the communication module 3 is connected to each test board in the valve-controlled testing device 2, ensuring that each test board can maintain real-time communication with the RTDS real-time simulation device 1. The RTDS real-time simulation device 1 sends the real-time simulated module capacitor voltage, bridge arm current, and other signals to the valve-controlled testing device 2 through the communication module 3, enabling dynamic adjustment of the simulated module capacitor voltage, ultimately making the average module capacitor voltage received by the energy router's main control equipment more real-time.

[0053] In one optional implementation, the RTDS real-time simulation device 1 directly simulates the operating status of each sub-module of the energy router converter valve based on the first preset number of energy router converter valves, generates corresponding feedback information, and then sends it to the energy router monitoring equipment through the energy router converter valve control device. The valve control testing device 2 generates corresponding feedback status based on the feedback signal sent by the external controller, and generates corresponding feedback information based on the feedback status, and sends it to the energy router monitoring equipment through the energy router converter valve control device.

[0054] In one specific embodiment, the RTDS real-time simulation device 1 can directly simulate the operating status of each sub-module of the converter valve, including electrical information such as voltage and current of the sub-modules and the fault status of the sub-modules. After generating feedback information, it is sent to the energy router monitoring equipment through the energy router converter valve control device. By comparing the feedback information and the corresponding feedback status displayed on the monitoring equipment, the user can determine whether the control program of the central control board in the energy router converter valve control device and the valve control test device 2, as well as the RTDS real-time simulation device 1, are faulty.

[0055] In one alternative implementation, such as Figure 3As shown, the valve control test device 2 includes: at least one test board 21, a power module 22, and a display device 23. Each test board 21 has at least one built-in central control board program for generating a corresponding simulated response based on a second trigger command. The test board 21 is also used to generate a corresponding return check status based on the return check signal sent by an external controller, and based on the return check status, generate corresponding return check information, which is then sent to the energy router monitoring equipment via the energy router converter valve control device. The power module 22 supplies power to the test board 21. The display device 23 is connected to the test board 21 and displays the simulated response and return check status. The display device 23 includes an oscilloscope, a waveform recorder, etc.

[0056] In one specific embodiment, since the converter valve includes multiple sub-modules, and each sub-module is composed of multiple switching devices, in actual operation, the switching state of one switching device is determined by a central control board. Therefore, in order to detect whether the program built into the central control board and the program built into the energy router converter valve control device are correct, this embodiment of the invention sets up multiple test boards 21. Each test board 21 is used to simulate one sub-module. Each test board 21 has multiple central control board programs (including trigger programs and return check programs) built in it. The number of central control board programs is the same as the number of switching devices of the sub-module simulated by the test board 21.

[0057] After receiving the second trigger command, the test board 21 parses the second trigger command, extracts multiple trigger command bits in the protocol, and sends the trigger command bits in sequence to the test area built into the test board 21. The test area makes a corresponding simulated response to the trigger command bits.

[0058] like Figure 4 As shown, each test board 21 includes at least one pair of input optical heads 211 and output optical heads 212. The input optical heads 211 are connected to the energy router converter valve control device through a trigger optical fiber, and the output optical heads 212 are connected to the energy router converter valve control device through a feedback optical fiber.

[0059] In one alternative implementation, such as Figure 5 As shown, the test board 21 includes: a test control circuit 213, a return signal action circuit 214, and at least one trigger command detection circuit 215.

[0060] like Figure 5As shown, the test control circuit 213 of this embodiment is connected to the valve control device of the energy router converter valve. The test control circuit 213 has at least one built-in central control board program. Each central control board program corresponds to one trigger command. After each trigger command is parsed by the central control board program, a corresponding trigger command bit is generated, and then the trigger command bit is sent sequentially to the trigger command detection circuit 215. It should be noted that the test control circuit 213 of this embodiment can be a control circuit based on an FPGA logic chip, but this is only an example and not a limitation.

[0061] In this embodiment of the invention, the trigger command detection circuit 215 is connected to the test control circuit 213 to simulate a switching device in a sub-module of the converter valve. The trigger command bit controls the change of the electrical state of the trigger command detection circuit 215, thereby making a corresponding simulated response.

[0062] like Figure 5 As shown, in this embodiment of the invention, the return check signal action circuit 214 is connected to the test control circuit 213. The return check signal action circuit 214 generates a corresponding return check status based on the return check signal sent by the external controller and sends it to the test control circuit 213. The test control circuit 213 generates corresponding return check information based on the return check status and transmits it back to the energy router converter valve control device.

[0063] In one alternative implementation, such as Figure 6 As shown, the return signal action circuit 214 includes: a return channel selection switch, a rotary encoder, and at least one push-button switch K2. The return channel selection switch is connected to the test control circuit and is used to select the return fiber optic cable and central control board program to be tested, and sends the selection result to the test control circuit 213. One end of both the rotary encoder and the push-button switch K2 is connected to the test control circuit 213, and the other end is grounded. It should be noted that the rotary encoder is connected to the display device 23 (which can be a digital tube), and the push-button switch K2 can be grounded through an LED.

[0064] In this embodiment of the invention, a rotary encoder is used to change the voltage and current values ​​according to the feedback signal. Specifically, the rotary encoder sends different voltage and current change values ​​to the test control circuit 213 by rotating in different directions, thereby simulating the voltage and current change values ​​during the operation of the converter valve submodule. The central control board program increases or decreases the rated voltage and current values ​​according to the voltage and current change values, simulating the fluctuation of the voltage / current acquisition values ​​of the central control board.

[0065] In this embodiment of the invention, the on / off state of the push button switch K2 is used to characterize the fault flag bit. That is, the number of push button switches is the same as the number of switching devices in the converter valve submodule. Each push button switch represents a unique switching device, and the on or off state of the push button switch indicates whether the switching device it represents is faulty.

[0066] In one alternative implementation, such as Figure 2 As shown, the testing device also includes a switch K1, one end of which is connected to the other end of the communication module 3, and the other end of which is connected to each test board 21 in the valve control testing device 2.

[0067] In one specific embodiment, the display device 23 has a mode switching function. Mode 1: The test board 21 uses local data for testing, that is, the switch K1 disconnects the connection channel with the communication module 3. This mode can be selected for simulation testing when real-time simulation testing is not required or the accuracy requirements of the parameters are not high. Mode 2: The test board uses the communication module interface for testing, that is, the switch K1 closes the connection channel with the communication module 3. This mode can be selected for simulation testing when the test device needs real-time parameters or the accuracy requirements of the parameters are high.

[0068] In one optional implementation, the trigger pulses of modules at different levels utilize carrier phase-shifting technology, with different carriers at different levels having different phases. The number of layers required to construct the energy router equivalent circuit in RTDS is divisible by the actual number of circuit layers in the engineering project, resulting in N. The trigger pulses of the converter valve module are connected to the RTDS real-time simulation device 1 in the order of 1, 1+N, 1+2N…

[0069] The test device for the valve control device of the energy router converter valve provided by this invention sends a portion of the trigger command to the valve control test device and another portion to the RTDS real-time simulation device after the main control device issues a trigger command. The two devices coordinate to complete the simulation test of the multi-module converter valve control device, thus overcoming the limitation of RTDS in simulating converter valves at a full scale. On the other hand, the RTDS real-time simulation device and the valve control test device are connected through a communication module, which improves the real-time performance of the test device during simulation testing.

[0070] This invention also provides a test method for a converter valve control device of an energy router, based on the above-mentioned test device, such as... Figure 7 As shown, the test method includes the following steps:

[0071] Step S1: Receive the first trigger command sent by the energy router converter valve control device. The first trigger command is used to trigger the first preset number of energy router converter valves built by the RTDS real-time simulation device. The RTDS real-time simulation device makes a corresponding simulation response according to the first trigger command.

[0072] Step S2: Receive the second trigger command sent by the energy router converter valve control device. The second trigger command is used to trigger the energy router converter valves of the second preset number of levels set up by the valve control test device. The valve control test device makes a corresponding simulated response according to the second trigger command.

[0073] Step S3: By comparing the trigger command and the corresponding simulation response, determine whether the control program of the central control board in the energy router converter valve control device, the valve control test device and the RTDS real-time simulation device are faulty.

[0074] In one specific embodiment, the energy router converter valve control device analyzes and modulates the modulated wave and control signal sent by the energy router main control equipment, and then sends a portion of the trigger command to the RTDS real-time simulation device and another portion to the valve control test device. The control program of the RTDS real-time simulation device receives the trigger command, generates a trigger command control word, and makes a corresponding simulated response. The central control board program built into the valve control test device receives the other portion of the trigger command and makes a corresponding simulated response.

[0075] Users can determine whether the energy router converter valve control device, the central control board control program in the valve control test device, and the RTDS real-time simulation device are faulty by comparing the simulated reaction of the RTDS real-time simulation device and the valve control test device with their corresponding modulation waves.

[0076] In one optional implementation, the testing method further includes the following steps:

[0077] Step S4: Generate the corresponding return check status based on the return check signal sent by the external controller;

[0078] Step S5: Generate corresponding return inspection information based on the return inspection status;

[0079] Step S6: Send the return inspection information to the energy router monitoring equipment through the energy router converter valve control device;

[0080] Step S7: By comparing the return inspection information and corresponding return inspection status displayed by the monitoring equipment, determine whether the control program of the central control board in the energy router converter valve control device, the valve control test device and the RTDS real-time simulation device are faulty.

[0081] In one specific embodiment, the RTDS real-time simulation device directly simulates the operating status of each sub-module of the energy router converter valve based on the first preset number of energy router converter valves, generates corresponding feedback information, and then sends it to the energy router monitoring device through the energy router converter valve control device. The valve control testing device generates corresponding feedback status based on the feedback signal sent by the external controller, and generates corresponding feedback information based on the feedback status, which is then sent to the energy router monitoring device through the energy router converter valve control device. By comparing the feedback information and corresponding feedback status displayed on the monitoring device, the user can determine whether the energy router converter valve control device, the central control board control program in the valve control testing device, and the RTDS real-time simulation device are faulty.

[0082] The test method for the valve control device of the power router converter valve provided by the present invention sends a part of the trigger command to the valve control test device and another part to the RTDS real-time simulation device after the main control device issues the trigger command. The two devices coordinate to complete the simulation test of the valve control device of the multi-module converter valve, which makes up for the shortcomings of RTDS in not being able to simulate the converter valve in full scale.
