In the embodiment of the application, a single-phase earth fault mode is discussed, and a related person can design the application with a little improvement according to actual requirements in the case of a multi-phase earth fault mode, but the design is within the protection scope of the application.

Similarly, fault simulation for B-phase and C-phase can also be implemented by corresponding control strategies.
In an alternative embodiment, the control logic may also be implemented in other ways, for example, a Programmable Logic Controller (PLC) may be used to achieve precise control over fault simulation. By programming the PLC, a specific fault simulation sequence can be set, thereby simulating various complex fault conditions in the test.
In the embodiment of the application, a specific simulation principle circuit diagram shown in fig. 2 is designed, wherein the detailed connection relation of the fault simulation area is designed control logic, and a master control room comprises a master control workstation and an optical fiber switch; the fault simulation area comprises a single-phase grounding fault switch, an adjustable power resistor, a single-phase grounding fault mode switching device, a grassland grounding point, a mud grounding point, a asphalt path grounding point, a metallic grounding point, a broken cable grounding point, a broken insulator grounding point, a high-voltage capacitor C1 and a high-voltage capacitor C2; the main control workstation is connected with the controller A and the controller B through the optical fiber switch; the single-phase grounding fault switch comprises an A-phase 10kV contactor, a B-phase 10kV contactor, a C-phase 10kV contactor and a controller A, wherein the controller A controls the opening and closing of the A-phase 10kV contactor, the B-phase 10kV contactor and the C-phase 10kV contactor through cables;
In an alternative embodiment, the control output is latched when the voltage value detected by the controller B voltage detection module is greater than 30% of the nominal voltage value UN;
in an alternative embodiment, the nominal voltage value UN is AC6000V.
In an embodiment of the present application, the preset grounding point includes:
A plurality of different types of grounding points established for the first simulated failure mode set;
the number of the preset grounding points is not smaller than the number of the first simulation fault mode concentrated fault modes.
In an alternative embodiment, the number of preset grounding points is not less than the number of fault modes in the first simulation fault mode set, so as to ensure that each fault mode can be accurately simulated. For example, if the first set of simulated failure modes includes six different failure modes, then at least six preset ground points are required to correspond to those failure modes.
In an alternative embodiment, the preset ground point may be an actual physical ground point, or may be a ground point simulated in simulation software.

The first instruction and the second instruction include:
the first instruction is an instruction for controlling the phase;
the second instruction is an instruction for accessing any preset grounding point.
It should be noted that other instructions exist in the present application, for example, the main control workstation sends an instruction for adjusting the adjustable power resistor to 0 ohm to the controller a, sends an instruction for controlling the single-phase grounding fault switch to open the 10kV contactor of a certain phase after the test is finished, and the like, and the instructions are not limited here, because the instructions can be correspondingly designed along with the dispatch of the first instruction and the second instruction.
In an alternative embodiment, the first instruction and the second instruction may be issued by the master workstation via an optical fiber, ensuring accuracy and fast response of the control command.

In an alternative embodiment, the relevant technician may design different control centers to implement the dispatch of the instructions according to actual needs, for example, a central control center may be designed, which is responsible for receiving the instructions from the master workstation and distributing the instructions to the respective controllers. The design can improve the expandability and flexibility of the system, so that the system can adapt to a larger-scale real-world test platform of the power distribution network.
In an alternative embodiment, the failover strategy may also be established with consideration of the real-time and accuracy of the failure simulation. To achieve this goal, a fail-over strategy also includes a fail-over feedback mechanism. For example, after performing the failover operation, the controller a and the controller B may feed back the operation result to the master workstation. And the main control workstation judges whether the fault simulation is successful according to the feedback information, and adjusts a subsequent fault simulation strategy according to the fault simulation.
In an alternative embodiment, the establishment of the fail-over policy may also take into account the safety of the fault simulation. To ensure the safety of operators and equipment, safety precautions are included in the fail-over strategy. For example, prior to performing fault simulation, the system may perform a series of safety checks including, but not limited to, checking whether all devices are in normal operation, confirming whether all operators have been evacuated to a safe area, etc. Only after confirming that all security conditions are met will the system perform a fail-over operation.
In an alternative embodiment, the establishment of the fail-over strategy may also take into account the repeatability of the fault simulation. To ensure that the results of each fault simulation are comparable, a detailed record of simulation parameters is included in the fail-over strategy. For example, each time a fault is simulated, the system records information such as the type of fault simulated, the parameters of the fault simulated, the time of the simulation, etc. This information will be stored in the system for later analysis and research.
It should be noted that, the specific design may be increased or decreased according to the actual design requirement of the related technician, but the related increase or decrease operation of the underlying control logic for fault simulation by controlling the receiving and transmitting command should be within the protection scope of the present application;
in the embodiment of the application, as shown in fig. 2, a main control workstation is connected with a controller A and a controller B through an optical fiber switch;
In the embodiment of the application, the single-phase grounding fault switch comprises an A-phase 10kV contactor, a B-phase 10kV contactor, a C-phase 10kV contactor and a controller A, wherein the input end of the A-phase 10kV contactor is connected with a 10kV grounding fault point A, the input end of the B-phase 10kV contactor is connected with a 10kV grounding fault point B, and the output ends of the A-phase 10kV contactor, the B-phase 10kV contactor and the C-phase 10kV contactor are connected with an adjustable power resistor input end after being connected.
In the embodiment of the application, the output end of the adjustable power resistor is respectively connected with the input end of the high-voltage capacitor C1 and the input end of the single-phase grounding fault mode switching device.
In the embodiment of the application, the output end of the high-voltage capacitor C1 is connected with the input end of the high-voltage capacitor C2, and the output end of the high-voltage capacitor C2 is connected with the ground. The connection point M of the high-voltage capacitor C1 and the high-voltage capacitor C2 is connected with a voltage detection module of the controller B. The single-phase grounding fault mode switching device comprises a knife switch 1, a knife switch 2, a knife switch 3, a knife switch 4, a knife switch 5, a knife switch 6 and a controller B, wherein the input end of the knife switch 1 is respectively connected with the input end of the knife switch 2, the input end of the knife switch 3, the input end of the knife switch 4, the input end of the knife switch 5 and the input end of the knife switch 6, the output end of the knife switch 1 is connected with a lawn, the output end of the knife switch 2 is connected with a mud land, the output end of the knife switch 3 is connected with a asphalt way, the output end of the knife switch 4 is connected with the ground, the output end of the knife switch 5 is connected with a broken cable A, and the output end of the knife switch 6 is connected with a broken insulator.
In the embodiment of the application, the controller A can receive a control instruction of the main control workstation, namely a first instruction, and control the opening and closing of the A-phase 10kV contactor, the B-phase 10kV contactor and the C-phase 10kV contactor.

In an alternative embodiment, if a skilled person uses three single phase earth fault mode switching devices for different phases instead of a single phase earth fault mode switching device according to the present application, the method shall also be within the scope of the present application.
It should be noted that establishing the first failover strategy for different phases based on the first set of simulated failure modes enables fast localization and accurate handling of single-phase-to-earth faults in the distribution network. Through the designed fault switching strategy, various possible fault conditions can be simulated, so that in actual operation, when single-phase earth fault occurs, operators can rapidly identify the fault type and take corresponding treatment measures. In addition, through the diversified design of preset grounding points, the grounding faults under different environments, such as grasslands, mud lands, asphalt ways and the like, can be simulated, so that the difference of the influences of different grounding conditions on the faults can be researched, and the design and maintenance strategies of the power distribution network are optimized.
S103, obtaining a fault mode to be simulated, and switching the fault mode based on the first fault switching strategy.
In the embodiment of the application, obtaining the fault mode to be simulated, and switching the fault mode based on the first fault switching strategy comprises the following steps:
Obtaining a fault mode to be simulated, wherein the fault mode to be simulated is a single-phase simulation fault mode, namely, any one phase of A, B, C three phases of phase simulation fault modes;
The first fault switching strategy performs fault mode switching aiming at the corresponding single-phase analog fault mode.
For example, assuming that a phase A metallic fault is simulated, the main control workstation sends an instruction for adjusting the adjustable power resistor to 0 ohm to the controller A, after the adjustable power resistor is adjusted, the main control workstation sends a switch 4 closing instruction to the controller B, after the switch 4 is closed, the main control workstation sends a switch-on instruction for controlling the phase A phase 10kV contactor of the single-phase grounding fault switch, and after the test is finished, the main control workstation sends a switch-off instruction for controlling the phase A10 kV contactor of the single-phase grounding fault switch.
Illustratively, assuming a simulation of a phase B broken cable fault, the master workstation first issues an instruction to the controller a to adjust the adjustable power resistance to a specified value to simulate the resistive characteristics of the broken cable. Subsequently, the main control workstation sends an instruction of closing the disconnecting link 5 to the controller B so as to connect the broken cable simulation point. After the steps are completed, the main control workstation sends out a command for controlling the switching-on of the single-phase grounding fault switch B-phase 10kV contactor so as to simulate the grounding fault of the B-phase. After the fault simulation is completed, the main control workstation sends out a command for controlling the single-phase grounding fault switch B-phase 10kV contactor to open so as to end the fault simulation.
In summary, the invention provides a single-phase earth fault mode switching method of a real-world test platform of a power distribution network, which is used for acquiring a first simulated fault mode set of a target test platform, wherein the first simulated fault mode set comprises a plurality of different fault modes, establishing first fault switching strategies aiming at different phases based on the first simulated fault mode set, acquiring a to-be-simulated fault mode, and switching the fault modes based on the first fault switching strategies. The digital control mode is adopted, the main control workstation is utilized to send a control command through the optical fiber, so that the ground fault mode switching can be achieved, the links of power failure, electricity inspection and ground wire installation safety measures are saved, and the ground fault mode switching time and the test safety are greatly saved.
