[0003] However, the power system has multiple working modes, and real-time monitoring can only monitor and warn the operating status of the power system's current working mode in the current line or equipment configuration. This may lead to limitations in monitoring and warning. As a result, when the power system switches to other working modes, it may cause power system abnormalities. Summary of the invention

Afterwards, based on the current data, the electric power simulation system in different working modes is tested, and the test results of the electric power simulation system in different working modes can be obtained. Then, it can be determined whether the electric power simulation system is in a stable state through the test results of the electric power simulation system in different working modes. In this way, by testing the electric power simulation system in different working modes, the diversity of the test is increased, thereby improving the accuracy of the test. Furthermore, since the stable state is obtained based on the test results of different working modes; in this way, the working mode can be switched through the stable state, thereby ensuring that the electric power system can operate normally after switching the working mode.

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] The terms “first” and “second” in the description and claims of the present application are used to distinguish different objects rather than to describe a specific order of the objects.

[0033] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or modules is not limited to the listed steps or modules, but may optionally include other steps or modules that are not listed, or may optionally include other steps or modules that are inherent to these processes, methods, products or devices.

[0034] In addition, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present concepts in a specific way.

[0035] In the information and communication industry, electricity is the key to ensure the normal operation of communication networks and equipment. In order to ensure the normal operation of the power system, the power system needs to be monitored in real time. The current distribution monitoring system is mainly divided into device-level monitoring and system-level monitoring. Device-level monitoring can realize real-time display of its own operating status and alarms at the device level by entering the equipment of the power system and binding the operating parameters of each device to the device. System-level monitoring establishes the connection routing relationship of each power device in the form of a distribution system diagram. By binding the operating parameters of each device to the device, it can realize real-time display of its own operating status and alarms at the device level, and can also display the connection routing relationship within the distribution system and the architecture relationship between distribution systems. The equipment entered into the power system includes transformers, low-voltage distribution cabinets, uninterruptible power systems (UPS) systems, switching power supplies, and head cabinets. The operating parameters of each device include voltage, current, power, power factor, and electricity.

[0036] However, device-level monitoring and system-level monitoring can only monitor the operating status of the distribution system in real time. The power system has many working modes. Real-time monitoring can only monitor and warn the operating status of the current working mode of the power system in the current line or equipment configuration. It cannot display other working modes outside of this working mode, nor can it predict in advance the operating status of other working modes under the current line or equipment configuration. Therefore, when the power system switches to other working modes, if the line or equipment configuration is unreasonable, it may cause power system abnormalities.

[0037] In response to the technical problems pointed out in the background technology section of this application, an embodiment of the present application provides a verification method for an electric power system. In this method, the current data of an electric power simulation system under normal working conditions is obtained, and the electric power simulation system includes multiple working modes, and the working modes are used to indicate the power supply circuit of the electric power system under different operating conditions. Afterwards, based on the current data, the electric power simulation system in different working modes is tested, and the test results of the electric power simulation system in different working modes can be obtained. Then, it can be determined whether the electric power simulation system is in a stable state through the test results of the electric power simulation system in different working modes. In this way, by testing the electric power simulation system in different working modes, the diversity of the test is increased, thereby improving the accuracy of the test. Furthermore, since the stable state is obtained based on the test results of different working modes; in this way, the working mode can be switched through the stable state, thereby ensuring that the electric power system can operate normally after switching the working mode.

[0038] The implementation environment of the embodiments of the present application is introduced below.

[0039] like Figure 1 As shown, an electric power simulation system provided by an embodiment of the present application includes: a main power system, a backup power system, an AC train head cabinet, a DC train head cabinet, a generator set, and a low-voltage interconnection bus. Among them, the main power system is connected to the AC train head cabinet, the main power system is connected to the DC train head cabinet, the backup power system is connected to the AC train head cabinet, the backup power system is connected to the DC train head cabinet, the generator set is connected to the main power system, the generator set is connected to the backup power system, the low-voltage interconnection bus is connected to the main power system, and the low-voltage interconnection bus is connected to the backup power system.

[0040] Among them, the main power system is the same as the backup power system. Taking the main power system as an example, the main power system includes a low-voltage distribution system, a UPS system, a switching power supply system, and a battery pack. The low-voltage distribution system includes a transformer, a low-voltage incoming line cabinet, a low-voltage contact cabinet, an electric compensation cabinet, a low-voltage dual power conversion cabinet, and a low-voltage feeder cabinet. The battery pack includes a switching power supply system battery pack and a UPS system battery pack.

[0041] It should be noted that, regarding the system architecture of the backup power system, reference can be made to the system architecture of the main power system, which will not be elaborated here.

[0042] In a possible design, each power device in the power simulation system corresponds to a switch connected to each circuit device, and the simulation of different working states of the simulated power system is achieved by opening and closing the switches of each circuit device.

[0043] In some embodiments, the power simulation system further includes: a controller. The controller is used to control the closure of the switch of the low-voltage interconnection busbar when a main power failure occurs in the main power system, so that the low-voltage interconnection cabinet of the backup power system is connected to the low-voltage interconnection cabinet of the main power system through the low-voltage interconnection busbar, and the backup power system supplies power to the main power system through the low-voltage interconnection cabinet. It should be noted that the operation of the main power failure in the backup power system can refer to the operation of the main power failure in the main power system, which will not be repeated here.

[0044] In a possible design, the operating states of the UPS system include main input mode, bypass input mode, and manual maintenance bypass input mode. In a normal state, the UPS system supplies power to the load through the main circuit. If the main circuit fails, the UPS system supplies power to the load through the bypass. If the bypass fails, the UPS system supplies power to the load through the manual maintenance bypass.

[0045] In one possible implementation, when both the main power system and the backup power system experience a power failure and the generator set has not yet started, the UPS system supplies power to the load via the UPS system battery pack, and the switching power system supplies power to the load via the switching power system battery pack.

[0046] In another possible implementation, both the main power system and the backup power system experience a main power failure, and the generator sets have been started to supply power to the main power system and the backup power system.

[0047] In one possible design, the AC main cabinet distributes power to the load equipment through a dual-circuit incoming line.

[0048] For example, the AC power supply cabinet has two independent power supply inlets, A and B.

[0049] It can be understood that the AC power supply cabinet receives the power output by the UPS system through dual-line input and distributes it to various load devices, which can ensure the stability of the power supply provided by the power simulation system to the load devices.

[0050] It should be noted that the way in which a DC power supply cabinet supplies power to load equipment can refer to the way in which an AC power supply cabinet distributes power to load equipment, which will not be described in detail here.

[0051] The embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

The low voltage interconnection bus, the generator set, the AC train head cabinet, and the DC train head cabinet are connected to the main power system and the backup power system, respectively.

[0056] In a possible implementation, a power simulation system is obtained by simulating a target power system.

[0057] In a possible design, initial simulation parameters of the target power system are obtained, simulation is performed based on the initial simulation parameters and the preset connection relationship, and a power simulation system of the target power system is constructed. The initial simulation parameters include: the rated capacity of each power device in the main power system, the rated capacity of each power device in the backup power system, the rated capacity of the generator set, the rated capacity of the AC train head cabinet, and the rated capacity of the DC train head cabinet.

[0058] In a possible implementation, current data of the power simulation system in a normal working state is obtained through real-time acquisition.

[0059] The power simulation system includes multiple working modes, which are used to indicate the power supply circuits of the power system under different operating conditions.

[0060] In an embodiment of the present application, the working mode of the power simulation system includes but is not limited to at least one of the following working modes: normal mode, first fault mode, second fault mode and third fault mode. The normal mode is used to indicate the power supply circuit of the power system when the UPS system, the main power system and the backup power system are normal. The first fault mode is used to indicate the power supply circuit of the power system when the UPS system fails, the second fault mode is used to indicate the power supply circuit when the main power system or the backup power system fails, and the third fault mode is used to indicate the power supply circuit when the main power system and the backup power system fail at the same time.

[0061] In a possible design, when the working mode of the power simulation system is the normal mode, the power supply circuit of the power simulation system includes: an AC power supply circuit and a DC power supply circuit. The AC power supply circuit is a power supply circuit when the load is AC power, and the DC power supply circuit is a power supply circuit when the load is DC power.

The UPS system bypass fault power supply circuit includes: a main low-voltage power distribution system connected to a main UPS system manual maintenance bypass, and a main UPS system manual maintenance bypass connected to an AC power supply cabinet.

[0063] In another possible design, when the working mode of the power simulation system is the second fault mode, the second fault mode includes a main power system fault power supply circuit and a backup power system fault power supply circuit. The main power system fault power supply circuit includes a main power system fault AC power supply circuit and a main power system fault DC power supply circuit. The main power system fault AC power supply circuit is a power supply circuit when the load is AC power in the case of a main power system fault. The main power system fault DC power supply circuit is a power supply circuit when the load is DC power in the case of a main power system fault. The main power system fault AC power supply circuit includes: a low-voltage contact cabinet of the backup power system (which can be called a backup low-voltage contact cabinet) is connected to a low-voltage contact cabinet of the main power system (which can be called a main low-voltage contact cabinet) through a low-voltage contact bus, so that the main low-voltage distribution system is connected to the backup low-voltage distribution system. The main low-voltage distribution system is connected to the main road of the main UPS system, and the main road of the main UPS system is connected to the AC head cabinet. The main power system fault DC power supply circuit includes: the backup low-voltage contact cabinet is connected to the main low-voltage contact cabinet through a low-voltage contact bus, so that the main low-voltage distribution system is connected to the backup low-voltage distribution system. The main low-voltage power distribution system is connected to the main switch power system of the main power system, and the main switch power system is connected to the DC train head cabinet.

[0064] In another possible design, when the working mode of the power simulation system is the third fault mode, the third fault mode includes a UPS system battery pack power supply circuit, a switching power supply system battery pack power supply circuit, a generator AC power supply circuit, and a generator DC power supply circuit. The UPS system battery pack power supply circuit is a power supply circuit when the main power system and the backup power system fail at the same time, the generator is not started, and the load is AC power.

[0065] It should be noted that the power supply circuit of the backup power system in different working modes can refer to the power supply circuit of the main power system in different working modes, which will not be described in detail here.

[0066] S202. Based on the current data, test the power simulation system in different working modes to obtain multiple test results.

[0067] Wherein, one test result corresponds to one working mode, and the test result is used to indicate whether the power simulation system is in a stable state in the corresponding working mode.

[0068] In a possible implementation, for each working mode, a test result corresponding to the working mode is determined by a target operation. The target operation includes: determining a target mode, and determining a target device corresponding to the target mode. The target device is tested based on current data to obtain a test result corresponding to the target mode. The target mode is any one of a plurality of working modes, and the target device is all devices in a power supply circuit corresponding to the target mode through which current flows.

[0069] In a possible design, the target mode is determined by opening and closing the switches of each power device in the power simulation system.

[0070] In some embodiments, when the power simulation system is tested in normal mode, the battery pack is in a charging state.

[0071] It should be noted that when the working mode of the power simulation system is the third fault mode, the battery pack supplies power to the load. Afterwards, when the working mode of the power simulation system is switched to the normal mode, the battery pack needs to be charged.

[0072] S203: Generate a verification result based on multiple test results.

[0073] The verification result is used to indicate whether the power simulation system is in a stable state.

[0074] In a possible implementation, the verification result is a first result or a second result, the first result is used to indicate that the power simulation system is in a stable state, and the second result is used to indicate that the power simulation system is in an abnormal state. If each test result indicates that the power simulation system is in a stable state under the corresponding working mode, the first result is generated. If there is a test result indicating that the power simulation system is in an abnormal state under the corresponding working mode among the multiple test results, the second result is generated.

[0075] In another possible implementation, based on multiple test results, a target number is determined, where the target number is the number of test results indicating that the power simulation system is in a stable state in a corresponding working mode. If the target number is greater than a preset number threshold, a first result is generated. If the target number is less than the first number, a second result is generated.

[0076] It should be noted that the embodiment of the present application does not limit the preset number threshold. For example, the preset number threshold is 5, 6, 7, etc. Alternatively, the preset number threshold is related to the number of multiple test results.

[0077] Based on the above technical solution, the current data of the electric power simulation system under normal working conditions is obtained. The electric power simulation system includes multiple working modes, and the working modes are used to indicate the power supply circuit of the electric power system under different operating conditions. Afterwards, based on the current data, the electric power simulation system in different working modes is tested, and the test results of the electric power simulation system in different working modes can be obtained. Then, it can be determined whether the electric power simulation system is in a stable state through the test results of the electric power simulation system in different working modes. In this way, by testing the electric power simulation system in different working modes, the diversity of the test is increased, thereby improving the accuracy of the test. Furthermore, since the stable state is obtained based on the test results of different working modes; in this way, the working mode can be switched through the stable state, thereby ensuring that the electric power system can operate normally after switching the working mode.

[0078] The following introduces the test results of obtaining the power simulation system when operating in the target mode.

[0079] like Figure 3 As shown, a method for verifying a power system provided by an embodiment of the present application is provided. In the method, S202 may include:

[0080] S301: Determine a preset parameter threshold and a target algorithm corresponding to a target device.

[0081] Among them, the target algorithm is used to determine the parameters of the target device.

[0082] In a possible implementation, a target mode is determined. Then, based on the target mode, a power supply circuit corresponding to the target mode is determined. Then, the rated parameter of each device in the power supply circuit corresponding to the target mode can be used as a preset parameter threshold.

[0083] Exemplarily, the target mode is the second fault mode, the second fault mode includes a main power system fault power supply circuit and a backup power system fault power supply circuit. The rated parameters of each device in the main power system fault power supply circuit and the backup power system fault power supply circuit are used as preset parameter thresholds.

[0084] It should be noted that the rated parameter of the target device may be the rated current of the target device, the rated parameter of the target device may be the long-delay setting current value of the target device, or the rated parameter of the target device may be the rated capacity of the target device.

[0085] Exemplarily, the rated parameters of the target equipment can be the rated current of the low-voltage incoming cabinet, the rated current of the UPS system, the rated current of the low-voltage connecting cabinet, the rated current of the low-voltage dual power supply cabinet switching switch, the rated capacity of the transformer, the rated capacity of the generator set, the rated capacity of the UPS system, and the rated capacity of the switching power supply system.

[0088] In one possible design, when the target device is each device in the low voltage power distribution system, the target algorithm can satisfy Formula 1.

[0089] A1=1.2*(I1+(Q1 / 10*564+Q2 / 10*56.4) / 380 / 1.732)Formula 1.

[0090] Among them, A1 is used to indicate the parameters of the corresponding equipment in the low-voltage power distribution system, and is also used to indicate the parameters of the AC terminal cabinet or DC terminal cabinet. Q1 is used to indicate the rated capacity of the UPS system battery pack, and Q2 is used to indicate the rated capacity of the switching power supply system battery pack. I1 is used to indicate the current flowing through the corresponding equipment in the low-voltage power distribution system.

[0091] In a possible design, when the target device is a UPS system, the target algorithm may satisfy Formula 2.

[0107] S303: Compare the preset parameter threshold with the parameter of the target device to obtain a test result.

[0108] In a possible implementation, if the preset parameter threshold is greater than or equal to the parameter of the target device, it is determined that the target device is in a stable state. If the preset parameter threshold is less than the parameter of the target device, it is determined that the target device is in an abnormal state.

[0109] Exemplarily, the rated current of the low-voltage incoming cabinet circuit breaker is compared with the parameters of the low-voltage incoming cabinet circuit breaker. If the rated current of the low-voltage incoming cabinet circuit breaker is greater than or equal to the parameters of the low-voltage incoming cabinet circuit breaker, the low-voltage incoming cabinet is determined to be stable; if the rated current of the low-voltage incoming cabinet circuit breaker is less than the parameters of the low-voltage incoming cabinet circuit breaker, the low-voltage incoming cabinet is determined to be abnormal. The rated capacity of the transformer is compared with the parameters of the transformer. If the rated capacity of the transformer is greater than or equal to the parameters of the transformer, the transformer is determined to be stable; if the rated capacity of the transformer is less than the parameters of the transformer, the transformer is determined to be abnormal. The rated capacity of the generator set is compared with the parameters of the generator set. If the rated capacity of the generator set is greater than or equal to the parameters of the generator set, the generator set is determined to be stable; if the rated capacity of the generator set is less than the parameters of the generator set, the generator set is determined to be abnormal. The rated capacity of the UPS system is compared with the parameters of the UPS system.

The rated capacity of the switching power supply system is compared with the parameters of the switching power supply system. If the rated capacity of the switching power supply system is greater than or equal to the parameters of the switching power supply system, it is determined that the switching power supply system is stable; if the rated capacity of the switching power supply system is less than the parameters of the switching power supply system, it is determined that the switching power supply system is abnormal.

[0110] In one possible implementation, if the parameter of the target device is less than or equal to a preset parameter threshold, the test result is determined to indicate that the power simulation system is in a stable state in the corresponding working mode. If the parameter of the target device is greater than the preset parameter threshold, the test result is determined to indicate that the power simulation system is in an abnormal state in the corresponding working mode.

[0111] Exemplarily, when the working mode of the power simulation system is the normal mode, the parameters of each device in the AC power supply circuit and the DC power supply circuit are less than or equal to the preset parameter threshold, then the test results in this mode are used to indicate that the power simulation system is in a stable state in the normal mode. When the working mode of the power simulation system is the first fault mode, the parameters of the UPS system in the main fault power supply circuit of the UPS system are less than or equal to the preset parameter threshold, and the parameters of the low-voltage incoming cabinet are greater than the preset parameter threshold, then the test results in this mode are used to indicate that the power simulation system is in an abnormal state in the normal mode.

[0112] It should be noted that S301-S303 are for determining the test results when the power simulation system is running in the target mode. For each of the multiple working modes, the test results of each working mode can be determined by executing S301-S303 to obtain multiple test results.

[0113] Based on the above technical solution, the preset parameter threshold and target algorithm corresponding to the target device are determined, and the target algorithm is used to determine the parameters of the target device. After that, the current data is calculated by the target algorithm to obtain the parameters of the target device. Then, the preset parameter threshold and the parameters of the target device are compared to obtain the test results of the power system in the target mode. In this way, the stability of the target device can be determined by the test results, thereby determining the stable state of the power supply circuit of the power system in the target mode.
