[0027] Figure 1 It is a schematic diagram of the energy storage system architecture. Figure 1 As shown, the energy storage system includes a DC battery compartment 10, an inverter boost compartment 20 and an energy management system 30. The DC battery compartment 10 includes a fire protection system 101, an environmental management system 102, a cooling system 103, a power distribution cabinet 104, a battery system 105 and an auxiliary system 106. Among them, the DC battery compartment 10 can be used for energy storage and release; the inverter boost compartment 20 can be used for AC and DC voltage conversion, power control and electric energy conversion, connected between the DC battery compartment 10 and the public power grid to achieve the storage and release of DC battery compartment battery energy; the energy management system 30 is connected to the DC battery compartment 10 and the inverter boost compartment 20 respectively to manage and monitor their energy. The power distribution cabinet 104 can be used to provide the power supply required for the operation of the fire protection system 101, the environmental management system 102, the cooling system 103, the battery system 105, and the auxiliary system 106, and manage and monitor them. In addition, the local controller in the power distribution cabinet can establish a connection with the external inverter boost compartment and the energy management system through the communication interface to realize data interaction.

[0028] The fire protection system 101 includes a fire protection controller, a temperature detection sensor, a smoke detection sensor, a fire extinguishing device, an air intake and exhaust fan, an alarm sound and light alarm, etc.; the battery system 105 includes a battery module, a high-voltage box, a BMS, etc.; the environmental management system 102 includes an air conditioner, a dehumidifier, etc.; the water cooling system includes a liquid cooler, a cooling pipeline, etc.; the auxiliary system 106 includes a temperature and humidity sensor, a water immersion sensor, an explosion-proof lamp, an access control, a video surveillance, etc.

[0029] However, as the market's requirements for the space utilization of energy storage systems become increasingly higher, users hope that the energy storage system with the same footprint can provide more battery energy. Therefore, the internal space layout of the energy storage battery compartment is also being continuously optimized, resulting in the structure and electrical connections of the distribution cabinet to be adjusted accordingly.

[0030] At present, the current practice for testing the power distribution cabinet is to manually perform the following inspections: component layout inspection, wiring harness connection inspection, wiring harness alignment, safety test, power circuit partial power-on inspection, etc. However, most of the components in the distribution cabinet are installed on the beams in the cabinet in bulk, which easily causes confusion in component identification and inconvenience in operation. At the same time, the wiring paths of the components in the distribution cabinet cross frequently, resulting in low manual testing efficiency, poor test comprehensiveness, and low reliability of test results.

[0031] Therefore, in order to solve the above technical problems, the present invention provides the following technical solutions:

[0032] Figure 2 is a flow chart of a method for testing a power distribution combiner cabinet according to an embodiment of the present invention, such as Figure 2 As shown, the test method of the power distribution cabinet of this embodiment may include the following steps:

[0033] Step 201: In response to a test instruction, trigger a device simulation unit in a test device, so that the device simulation unit simulates the operating condition of a trigger device linked to a power distribution cabinet, and sends the operating condition to the power distribution cabinet;

[0034] In a specific implementation process, it can be based on Figure 1 The architecture of the energy storage system can develop and design test equipment for testing the distribution cabinet for various components connected to the distribution cabinet. Figure 3 This is a schematic diagram of the test system architecture of the power distribution cabinet. Figure 3 As shown, the test system 1 may include a test device 11 and a host computer 12. The test device 11 may include a device simulation unit 111, a test detection unit 112, a hardware interface unit (not shown in the figure) and a communication interface 113, etc.

[0035] When testing, the device simulation unit 111 and the test detection unit 112 are both electrically connected to the power distribution cabinet 104 through the hardware interface unit. Among them, the device simulation unit 111 can simulate the operating conditions of the fire protection system, battery system, environmental management system, water cooling system, auxiliary system, etc. connected to the power distribution cabinet 104 inside the DC battery compartment when they are actually connected to the power distribution cabinet 104, and can also simulate the operating conditions of the inverter booster cabin and energy management system, etc. when they are actually connected to the power distribution cabinet 104. In actual applications, it can be selected and expanded according to actual needs. The test detection unit 112 serves as the processing unit of the test device 11 itself to complete the corresponding test steps.

[0036] Specifically, when the test detection unit 112 detects a test instruction, it responds to the test instruction, thereby triggering the device simulation unit 111 in the test device 11, so that the device simulation unit 111 simulates the operating condition of the trigger device linked with the power distribution cabinet 104, and sends the operating condition to the power distribution cabinet 104. The test instruction can be input through the input unit in the test device 11, or can be connected to the host computer 12 through the communication interface 113, and sent to the test detection unit 112 by the host computer 12. The communication interface 113 is also connected to the power distribution cabinet 104, and the power distribution cabinet 104 and the host computer 12 can exchange data through the communication interface 113.

[0037] The triggering devices mentioned above are devices that send operating conditions to the distribution cabinet. For example, when the fire protection system, battery system, environmental management system, water cooling system, auxiliary system, PCS, etc. send operating conditions to the distribution cabinet, they can be triggering devices. However, when the fire protection system, battery system, environmental management system, water cooling system, auxiliary system, PCS, etc. receive instructions from the distribution cabinet and execute the instructions, these devices are no longer triggering devices, but execution devices.

[0038] It should be noted that when the equipment simulation unit simulates 111 and the operating conditions of the triggering device linked to the power distribution cabinet, it can be implemented in hardware and / or software, and this embodiment does not impose specific restrictions. For example, for the simulation of the fire protection system, a PLC or other programmable controller can be used to simulate the fire control cabinet, and the fire alarm and linkage logic can be programmed to use an analog signal generator to simulate input signals such as smoke and temperature sensors, and use relays or solid-state relays to simulate the control of output devices such as sprinkler valves. For the simulation of the environmental management system, temperature and humidity sensors and pressure sensors can be used to simulate environmental parameters, and temperature and humidity controllers, fans, humidifiers and other equipment can be used for simulation. Examples will not be given one by one here.

[0039] Step 202: Obtain feedback information of the power distribution cabinet for the operating condition;

[0040] In a specific implementation process, after the operating conditions of the triggering device linked to the distribution cabinet simulated by the equipment simulation unit are sent to the distribution cabinet, the distribution cabinet will perform corresponding actions according to the operating conditions and generate feedback information corresponding to the operating conditions so as to feed back the feedback information.

[0041] Specifically, if the local controller of the power distribution cabinet determines that an abnormality occurs when the equipment simulation unit simulates the flooding condition, the action performed may be to send a shutdown signal to the inverter booster cabin, energy management system, etc., change the state of the corresponding interface in the local controller, etc., and then use the generated shutdown signal, state change, etc. as feedback information corresponding to the flooding condition, and feed it back to the test detection unit via the hardware interface unit. The situations of other working conditions are similar to the above description, and no examples are given here one by one.

[0042] Step 203: Determine whether the power distribution cabinet has an abnormality based on the feedback information;

[0043] In a specific implementation process, corresponding benchmark information can be set for different operating conditions. After receiving the feedback information sent by the distribution junction cabinet, the received feedback information can be parsed, and then the received feedback information can be compared with the benchmark information corresponding to the simulated operating condition setting. If the two are consistent, it is determined that there is no abnormality in the distribution junction cabinet. If the two are inconsistent, it is determined that there is an abnormality in the distribution junction cabinet.

[0044] That is to say, when the wiring and components of the power distribution cabinet are normal, the local controller of the power distribution cabinet has corresponding action results after operating for different operating conditions, and the information corresponding to different results is relatively fixed, and the information corresponding to different results can be used as reference information. If the wiring and components of the power distribution cabinet are normal, its feedback information is consistent with the reference information. If the wiring and components of the power distribution cabinet are abnormal, its feedback information is inconsistent with the reference information.

[0045] Step 204: If the power distribution cabinet has an abnormality, output the abnormality test result of the power distribution cabinet.

[0046] In a specific implementation process, an output unit can be set in the test device. If an abnormality is detected in the power distribution cabinet, the abnormal test result of the power distribution cabinet can be output through the output unit. The output unit can be a display, an audible and visual alarm, etc. In this way, the tester can intuitively know that the power distribution cabinet has an abnormality through the output unit.

[0047] It should be noted that the test of the distribution cabinet is mainly to find abnormalities and prevent problematic distribution cabinets from leaving the factory. Therefore, here only the output of abnormal test results of the distribution cabinet when there are abnormalities in the distribution cabinet is explained. When there are no abnormalities in the distribution cabinet, there is actually no need to output them, so as to avoid too many output results, which may confuse the testers and make mistakes in distinguishing between abnormalities and normal conditions.

[0048] The test method of the distribution cabinet of the present embodiment connects the test device to the distribution cabinet and responds to the test instruction to trigger the equipment simulation unit in the test device, so that the equipment simulation unit simulates the operating condition of the triggering device linked with the distribution cabinet, and sends the operating condition to the distribution cabinet, so as to obtain the feedback information of the distribution cabinet for the operating condition, and output the abnormal test result of the distribution cabinet when it is determined that the distribution cabinet has an abnormality. In this way, the correctness of the internal electrical circuit connection of the distribution cabinet and the comprehensiveness of the function can be verified, and it can be ensured that the electrical connection of the internal components of the distribution cabinet is normal before the distribution cabinet is installed, the component functions are normal, and the linkage strategy with the external component system is normal, thereby improving the test efficiency, test comprehensiveness, and reliability of the test results.

[0049] In a specific implementation process, in order to quickly locate the abnormal position and help the tester maintain the power distribution cabinet, the present invention also provides the following technical solutions:

[0050] Specifically, the reference information includes the status information of the detection end of the controller in the power distribution cabinet and the status information of the execution end of the controller; wherein the detection end of the controller is a port for receiving the operating condition, and the execution end of the controller is a port for sending a control signal to the execution device linked to the power distribution cabinet based on the operating condition. If the feedback information is inconsistent with the status information of the detection end, it is determined that there is an abnormality in the line between the power distribution cabinet and the trigger device; if the feedback information is inconsistent with the status information of the execution end, it is determined that there is an abnormality in the line between the power distribution cabinet and the execution device.

[0051] Taking the flooding condition as an example, if the state change in the feedback information is consistent with the state change corresponding to the reference information, it is determined that the two are consistent, indicating that the line, components, etc. between the water flooding abnormality trigger end (water flooding sensor) and a certain interface of the local controller of the distribution cabinet are normal, that is, there is no abnormality in the line between the distribution cabinet and the triggering device. Conversely, if the state change in the feedback information is inconsistent with the state change corresponding to the reference information, it is determined that the two are inconsistent, indicating that the line, components, etc. between the water flooding abnormality trigger end (water flooding sensor) and a certain interface of the local controller of the distribution cabinet are abnormal, that is, there is an abnormality in the line between the distribution cabinet and the triggering device.

[0052] If both the feedback information and the reference information contain the shutdown signal of device X, then the two are determined to be consistent, indicating that the line, components, etc. between the distribution cabinet and device X are normal, that is, there is no abnormality in the line between the distribution cabinet and the execution device; conversely, if the feedback information does not contain the shutdown signal of device X, but the reference information contains the shutdown signal of device X, then the two are determined to be inconsistent, indicating that the line, components, etc. between the distribution cabinet and device X are abnormal, that is, there is an abnormality in the line between the distribution cabinet and the execution device.

[0053] In a specific implementation process, different output methods can be used for different abnormalities in the power distribution cabinet, so as to quickly prompt the tester to the location of the abnormality. That is to say, if there is an abnormality in the line between the power distribution cabinet and the trigger device, the abnormal test result is output in a first way; if there is an abnormality in the line between the power distribution cabinet and the execution device, the abnormal test result is output in a second way. For example, the first output method is sound, and the second output method is sound plus light, etc.

[0054] It should be noted that different output methods can be used for different trigger devices and different execution devices to output abnormal test results. For example, for trigger device A, two beeps can be used to output abnormal test results, while for trigger device B, three beeps can be used to output abnormal test results. Examples are not given one by one here.

[0055] In a specific implementation process, when it is detected that the feedback information is consistent with the status information of the execution end, in order to intuitively know that the distribution cabinet can normally operate the corresponding function, the execution device can be triggered to respond to the control signal issued by the execution end. For example, an audible and visual warning light can be used as an execution device, and a corresponding signal can be issued to indicate that the execution device can execute the action.

[0056] In a specific implementation process, in order to be able to remotely test the power distribution cabinet, the operating condition and the feedback information can be sent to the host computer, so that when the host computer determines that the power distribution cabinet is abnormal based on the feedback information and the reference information corresponding to the operating condition, the host computer outputs the abnormal test result of the power distribution cabinet and / or generates an abnormal test report of the power distribution cabinet;

[0057] Among them, the operating conditions and feedback information of the triggering equipment can be Figure 2The abnormal test report includes at least one of abnormal position information of the power distribution cabinet, abnormal handling measures and the number of abnormal times corresponding to the operating condition, and the abnormal position information includes abnormality in the line between the power distribution cabinet and the trigger device, and / or abnormality in the line between the power distribution cabinet and the execution device.

[0058] It should be noted that the process by which the host computer determines that there is an abnormality in the power distribution cabinet based on the feedback information and the reference information corresponding to the operating condition, and the process of determining the location of the abnormality are basically consistent with the above description and will not be repeated here.

[0059] In a specific implementation process, when the host computer outputs the abnormal test results of the power distribution cabinet, it can be output in the form of a pop-up window, so as to remind the tester that there is an abnormality in the test and the abnormality handling needs to be implemented. After the tester completes and confirms the abnormal handling, the host computer reminds the tester to enter the abnormal handling measures and record them, and then reminds the tester to retest the abnormal items. After the test is passed, the tester is prompted to continue to perform subsequent item point tests, and the abnormal handling measures are recorded in the abnormal test report, so that when the abnormality occurs again in the future, the tester can be reminded how to handle the abnormality.

[0060] In a specific implementation process, it is also possible to count the number of abnormalities that occur in each operating condition and obtain the number of abnormalities corresponding to each operating condition. In this way, it is possible to provide basic data for strict control of the production and manufacturing process of the distribution cabinet. In other words, in the later production and manufacturing process of the distribution cabinet, it is possible to focus on the lines and components related to the abnormal operating conditions, thereby reducing the probability of abnormalities. In addition, it can also provide a basis for the reliable operation of the distribution cabinet. For example, in the later use of the entire energy storage system, if the failure rate of the distribution cabinet is high, the number of abnormalities corresponding to each operating condition in the abnormal test report can be used to determine whether the high failure rate of the distribution cabinet is highly correlated with the abnormal handling record of the previous distribution cabinet test.

[0061] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effect of the present application, different steps do not have to be executed in such an order. They can be executed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present application.

[0062] It is understood by those skilled in the art that all or part of the processes in the method for implementing the above-mentioned embodiment of the present application can also be completed by instructing the relevant hardware through a computer program, and the computer program can be stored in a computer-readable storage medium. When the computer program is executed by the processor, the steps of each of the above-mentioned method embodiments can be implemented. Among them, the computer program includes computer program code, and the computer program code can be in source code form, object code form, executable file or some intermediate form. The computer-readable storage medium may include: any entity or device, medium, U disk, mobile hard disk, disk, optical disk, computer memory, read-only memory, random access memory, electric carrier signal, telecommunication signal and software distribution medium that can carry the computer program code. It should be noted that the content contained in the computer-readable storage medium can be appropriately increased or decreased according to the requirements of legislation and patent practice in the jurisdiction. For example, in some jurisdictions, according to legislation and patent practice, computer-readable storage media do not include electric carrier signals and telecommunication signals.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
