Description

Technical Field

[0001] The present application belongs to the field of testing technology, and in particular relates to an energy storage valve control and testing system. Background Art

[0002] Flexible DC energy storage utilizes modular multilevel converter (MMC) technology to integrate energy storage units in a distributed manner into sub-modules. It has the advantages of high modularity, good harmonic characteristics, and low equivalent switching frequency, making it easy to implement large-capacity energy storage systems of 100 megawatts and above. Usually, the energy storage control and protection (i.e., control and protection) system of flexible DC energy storage has many control levels and complex interfaces. Before leaving the factory, a dynamic model test system needs to be built to simulate the working conditions of the engineering site and perform functional performance tests on the energy storage control and protection system. However, flexible DC energy storage has a high voltage level, high power, and a large primary equipment size, making it difficult to build a complete physical test system in the factory. Therefore, virtual testing and simulation methods are becoming increasingly popular.

[0003] However, the energy storage control and protection system is verified through a simulation environment, while the coordination logic of the controllers within the sub-modules cannot be tested online and can only be verified offline, which poses a risk of insufficient testing. Utility Model Content

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] Figure 1 This is a schematic diagram of a high-pressure direct-mounted energy storage valve (hereinafter referred to as an energy storage valve). Figure 1 As shown, the energy storage valve includes an upper arm and a lower arm, each of which includes protection devices S1 and S2, respectively, and m energy storage submodules. The energy storage submodules in the upper and lower arms are denoted by SM1#m and SM2#m, respectively, where m is 1, 2, 3, ..., n. Protection devices S1 and S2 are, for example, contactors or circuit breakers.

[0039] Among them, the topology of the energy storage valve submodule is as follows Figure 2 As shown, it includes a bypass switch K1, a disconnect switch K2, a power circuit, a filter capacitor C1, and a battery module BT1. The power circuit includes an upper switch tube T1 and a lower switch tube T2 connected in series between the positive and negative busbars. The switch tube is, for example, an insulated-gate bipolar transistor (IGBT). The battery module BT1 includes at least one battery cluster, each battery cluster includes one or more battery packs, and each battery pack includes one or more battery cells. In addition, Figure 2 A1 and A2 in the figure represent two connection ports, and each energy storage valve submodule is connected to the main circuit of the energy storage valve through the two connection ports A1 and A2, so as to be connected to the external circuit through the main circuit. Figure 2 The energy storage valve submodule shown can also be used for an AC energy storage valve.

[0040] Typically, during factory testing of high-pressure, direct-hung energy storage valves, the energy storage control and protection system is typically tested without connecting the submodules due to the large number of submodules and the difficulty of accessing them. Instead, a real-time digital simulation system (RTDS) is used to simulate the operating conditions of the energy storage valve submodules. However, the coordination logic of the sub-module controller (SMC), battery management controller (BMC), and sub-module battery management unit (SBMU) within the energy storage valve submodule cannot be tested online and can only be verified offline. This presents a risk of inadequate testing and makes it impossible to complete full-link testing of the energy storage valve control and protection system.

[0041] In this regard, an embodiment of the present application provides an energy storage valve control and protection test system, which can perform physical testing of the coordination logic of internal control and protection devices such as the sub-module control board and battery management control board of at least one energy storage valve sub-module, and also has RTDS to perform dynamic model testing of the operating conditions of other energy storage valve sub-modules, thereby completing the full-link test of the energy storage valve control and protection system.

[0042] According to some embodiments of this application, optionally, please continue to refer to Figure 3 , Figure 3 The following is a schematic diagram of the structure of the energy storage valve control and testing system provided in one embodiment of the present application. For ease of explanation, only the parts related to this embodiment are shown, which are detailed as follows:

[0043] The energy storage valve control and protection test system includes a host computer 100, a test tool 200, a first sub-module control board 300, a model board 400, a valve base control device (Valve Base Controller, VBC) 500 and a simulation device 600. The valve base control device 500 is connected to the simulation device 600 and the first sub-module control board 300. The valve base control device 500 is used to manage and control multiple energy storage valve sub-modules. The simulation device is used to simulate the operating conditions of multiple energy storage valve sub-modules. The test tool 200 is connected to the host computer 100, the valve base control device 500 and the simulation device 600. The test tool 200 is connected to the model board 400 through the first sub-module control board 300. The model board 400 is also connected to the test tool 200. The model board 400 is used to simulate the power circuit or includes the power circuit.

[0044] The host computer 100, such as a personal computer (PC), is used to issue commands and monitor feedback for the entire energy storage valve control and testing system, as well as record and save test results. The valve base control device 500 is the main control device for the energy storage valve. For example, the valve base control device 500 is used to provide power circuit control commands to the first submodule control board 300, controlling the closing and opening of the IBGT.

[0045] During the test, the valve base control device 500 configures the various signals and data necessary for the normal operation of the first submodule control board 300, completing the physical test of the first submodule control board 300. Simultaneously, the test fixture 200 obtains control instructions and feedback status from the simulator 600, via the valve base control device 500, from the protection devices S1 / S2 connected to the load or power grid, completing the physical test of the valve base control device 500. The protection devices S1 / S2 in the energy storage valve may include, for example, one or more of a contactor, a circuit breaker, a current sampling circuit, or a voltage sampling circuit. The valve base control device 500 monitors and manages the input and output of the energy storage valve through the protection devices S1 / S2.

[0046] The first submodule control board 300 is a physical component that can be used in the energy storage valve submodule, including circuits such as the SMC. Typically, the first submodule control board 300 is used to control the issuance and feedback of instructions for the power circuit, bypass switch, circuit breaker, and the like in the energy storage valve submodule. Therefore, during testing, the valve base control device 500 can issue control commands to the first submodule control board 300, enabling it to complete normal operation and receive feedback signals. For example, this can simulate the issuance and feedback of instructions for the power circuit, bypass switch, circuit breaker, and the like in the energy storage valve submodule. Furthermore, the first submodule control board 300 can also be tested for proper logical coordination between the BMC and the first submodule control board 300.

[0047] The model board 400 may, for example, include the power circuit of the energy storage valve submodule, or a circuit board capable of simulating the operating principle of the power circuit of the energy storage valve submodule. For example, because the interfaces of each submodule control board correspond, another submodule control board can be used to simulate the operating principle of the power circuit of the energy storage valve submodule, facilitating connection with the first submodule control board 300.

[0048] The simulation device 600 is, for example, a device running an RTDS model, which is used to provide the valve base control device 500 with information interaction and control of the energy storage valve sub-modules other than the energy storage valve sub-module (including the first sub-module controller 300) in the energy storage valve that is subjected to physical testing as mentioned above by the simulated energy storage control and protection system, and to provide the valve base control device 500 with control instructions and feedback status of the protection device S1 / S2 that is simulated and connected to the load or the power grid.

[0049] In the technical solution of the embodiment of the present application, the energy storage valve control and protection test system can realize the physical test of the first submodule control board 300 inside the energy storage valve submodule by configuring the test tool 200 through the host computer 100 and the instructions between the test tool 200 and the first submodule control board 300, between the first submodule control board 300 and the model board 400, and between the first submodule control board 300 and other components in the energy storage valve submodule, so as to make the test of the energy storage control and protection system more comprehensive.

[0050] The test fixture 200 can also simulate the energy storage control and protection system's control instructions and feedback status for energy storage valve submodules other than the aforementioned energy storage valve submodule undergoing physical testing through the simulation device 600, as well as provide control instructions and feedback status for simulated protection devices S1 / S2 connected to the power grid to the valve base control device 500, completing a full-link test of the entire energy storage control and protection system. The valve base control device 500 and first submodule control panel 300 of the energy storage valve control system are all connected to the simulation device 600, resulting in a test result that is closer to actual engineering practice. This allows for the convenience of physically switching the first submodule control panel 300 in and out of the simulation test system, enabling multi-dimensional testing and verification. The test results better cover various engineering operating conditions, improving the multi-scenario adaptability of the simulation test system.

[0051] According to some embodiments of this application, optionally, please continue to refer to Figure 4 , Figure 4 The following is a schematic diagram of the structure of the energy storage valve control and testing system provided in one embodiment of the present application. For ease of explanation, only the parts related to this embodiment are shown, which are detailed as follows:

[0052] The energy storage valve control and protection test system further includes a battery management control board 700 , which is connected to the test fixture 200 and the first submodule control board 300 .

[0053] The battery management control board (BMC) 700 is a physical component of the energy storage valve submodule, including circuitry such as the battery management system (BMC). Typically, the BMC 700 monitors and manages the battery modules within the energy storage submodule. Optionally, the BMC 700 can also issue and provide feedback on commands for the bypass switch and circuit breaker within the energy storage valve submodule.

[0054] During the test process, the host computer 100 can configure the test fixture 200 to issue control commands to the battery management control board 700, enabling the battery management control board 700 to complete normal operation and receive feedback signals. For example, this can simulate the issuance and feedback of commands to the bypass switch K1 and the circuit breaker K2 in the energy storage valve submodule. In addition, during the test process, the host computer 100 can configure the test fixture 200 to cause the simulation device 600 to provide the battery management control board 700 with information such as the current, voltage, power, or temperature of the battery cluster through the test fixture 200, enabling the battery management control board 700 to complete normal operation.

[0055] In the technical solution of the embodiment of the present application, the energy storage valve control and protection test system realizes physical testing of the battery management control board 700 inside the energy storage valve submodule by configuring instructions or data between the test tool 200 and the battery management control board 700, between the first submodule control board 300 and the battery management control board 700, and between the battery management control board 700 and the model board 400 through the host computer 100, so as to make the energy storage control and protection system test more comprehensive.

[0056] According to some embodiments of this application, optionally, please continue to refer to Figure 5 , Figure 5 The following is a schematic diagram of the structure of the energy storage valve control and testing system provided in one embodiment of the present application. For ease of explanation, only the parts related to this embodiment are shown, which are detailed as follows:

[0057] The energy storage valve control and protection test system further includes a submodule battery management device 800 , which is connected to the test fixture and the battery management control board.

[0058] The submodule battery management device 800 is a physical component that can be used for the energy storage valve submodule, including components such as the SBMU, which can monitor information such as the current, voltage, power or temperature of the battery cluster and transmit the information to the battery management control board 700.

[0059] During the test process, the host computer 100 can configure the test fixture 200, allowing the simulation device 600 to transmit information such as the current, voltage, power, or temperature of the battery cluster to the sub-module battery management device 800 through the test fixture 200. The sub-module battery management device 800 transmits this information to the battery management control board 700 to enable the battery management control board 700 to complete normal operation. During the test process, the control commands issued to the sub-module battery management device 800 enable the sub-module battery management device 800 to complete normal operation and receive feedback signals, such as the coordination logic between the battery management control board 700 and the sub-module battery management device 800.

[0060] In the technical solution of the embodiment of the present application, the energy storage valve control and protection test system realizes physical testing of the sub-module battery management device 800 inside the energy storage valve sub-module through the host computer 100, which configures the test tool 200 and the sub-module battery management device 800, and between the battery management control board 700 and the sub-module battery management device 800, so as to make the energy storage control and protection system test more comprehensive.

[0061] According to some embodiments of this application, optionally, please continue to refer to Figure 6 , Figure 6 The following is a schematic diagram showing the structure of a test fixture in an energy storage valve control and testing system provided in one embodiment of the present application. For ease of explanation, only the parts related to this embodiment are shown, which are detailed as follows:

[0062] The test tooling 200 includes a power board 210, a control board 220 and several interface boards 230 (i.e., interface boards). The power board 210 is connected to the control board 220 and several interface boards 230. The control board 220 is connected to the host computer 100 and several interface boards 230. Several interface boards 230 are connected to the first sub-module control board 300, the model board 400, the battery management control board 700 and the sub-module battery management device 800.

[0063] Among them, the control board 220 is a central processing unit (CPU) board, which is used for the management and control of the test tooling 200, and interacts with the external device through the interface board 230. The interface board 230 can also be integrated into a conventional interface tooling, sharing the power board 210 and the control board 220. Exemplarily, each interface board 230 has a number of fiber optic conversion interfaces that can send communication messages or modulate optical signals. Each fiber optic conversion interface can be configured into a specific functional interface through a configuration file, such as a simulated battery management interface, a bypass switch interface, an isolation switch interface, a model board communication interface, etc. In one embodiment, the test tooling 200 is also connected to the valve base control device 500 and the simulation device 600 through the interface board 230.

[0067] The first submodule control board 300 and the model board 400 each have at least two pairs of fiber optic conversion interfaces for modulating optical signals, each corresponding to two IGBTs in the power circuit. Within each pair of fiber optic conversion interfaces, one is used to control the IGBTs of the simulation model board 400, while the other is used to detect and provide feedback on the status of the IGBTs.

[0068] Switch mode selection interface P1 includes at least one pair of fiber-optic conversion interfaces for modulating optical signals. These interfaces simulate the switching states of the two IBGTs in model board 400, enabling them to be either connected or disconnected. This allows the switching states of the two IBGTs in model board 400 to correspond to or be opposite to their controlled states, allowing the first submodule control board 300 to detect whether they are in a normal or faulty state.

[0069] The first bypass switch interface P2 has at least one pair of optical fiber conversion interfaces for modulating optical signals (e.g., supporting a modulation frequency of 0-3 kHz), providing triggering instructions for the bypass switch K1 and feedback on the bypass switch K1's status to the first submodule control board 300.

The battery management control board interface P4 has two pairs of optical fiber conversion interfaces for sending communication messages, providing a simulation of the BMC sending messages using, for example, the FT3 communication protocol to the first submodule control board 300.

[0070] In the technical solution of the embodiment of the present application, the test tool 200 configures the issuance and feedback of various instructions necessary for the normal operation of the first sub-module control board 300 through the switch mode selection interface P1, the first bypass switch interface P2, and the first isolation switch interface P3, and simulates the necessary communication protocol messages for actual interaction with the battery management control board 700 through the battery management control board interface P4, which can provide the necessary signals and data for the normal operation of the first sub-module control board 300, thereby realizing physical testing of the first sub-module control board 300.

[0075] In the technical solution of the embodiment of the present application, the test tool 200 configures the issuance and feedback of various instructions necessary for the normal operation of the battery management control board 700 through the second bypass switch interface P5 and the second isolation switch interface P6, and configures various data necessary for the normal operation of the sub-module battery management device 800 through the sub-module battery management device interface P7, thereby realizing physical testing of the battery management control board 700 and the sub-module battery management device 800.

[0076] According to some embodiments of this application, optionally, please continue to refer to Figure 9 , Figure 9 The following is a schematic diagram of the structure of the energy storage valve control and testing system provided in one embodiment of the present application. For ease of explanation, only the parts related to this embodiment are shown, which are detailed as follows:

[0077] The energy storage valve control and protection test system also includes multiple communication modules 900. The sub-module battery management device interface P7 includes multiple communication interfaces. The multiple communication modules 900 are respectively connected to the multiple communication interfaces and the sub-module battery management device 800.

[0078] The communication module 900 is, for example, a fiber optic conversion module capable of transmitting communication messages or modulating optical signals. For example, there are three communication modules 900, namely communication interfaces P7.1, P7.2, and P7.3, which are used to transmit the voltage and temperature of the battery cluster, as well as the current and battery voltage transformation coefficient from the test fixture 200.

[0079] In the technical solution of the embodiment of the present application, the test fixture 200 realizes the interaction of multiple sampling parameters with the sub-module battery management device 800 through multiple communication modules 900, and the battery management control board 700 can obtain these sampling parameters through the sub-module battery management device 800 to achieve normal operation.

[0080] According to some embodiments of the present application, the model board 400 includes a second submodule control board. Utilizing the second (i.e., another) submodule control board to configure the model board 400 is simple and reliable; and since both have the same interface, it is convenient to connect with the actual first submodule control board 300.

[0081] According to some embodiments of the present application, each interface board 230 includes a plurality of fiber optic conversion interfaces, and provides a configuration method for the interface board 230 , wherein the fiber optic conversion interfaces have high communication speed and strong anti-interference capability.

[0082] According to some embodiments of the present application, the construction process of the energy storage valve control and testing system is as follows:

[0083] Set up the test environment, connect all interfaces of the sample to be tested to the test fixture 200, and then start the test fixture 200. The sample to be tested includes the first submodule control board 300, the model board 400, the valve base control device 500 and the simulation device 600, or also includes the battery management control board 700 and the submodule battery management device 800.

[0084] After the test fixture 200 is powered on, the initialization process loads the configuration XML file to communicate with the host computer 100. Default values are assigned to the output interfaces of the test fixture 200's interface board 230. The RTDS model is then started. Once the test sample is powered on and receives the default values, faults can be cleared. The test sample's status is monitored in real time by the test fixture 200 and the host computer 100. Once faults are cleared, the test environment is set up and the system can be unlocked for subsequent testing.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
