Embodiment Construction
[0061] Method and implementation steps proposed by the present invention:
[0062] Working principle of the present invention:
[0063] The core idea of the invention is to regard the secondary system of the tested intelligent substation as a whole, incorporate the merging unit and the network switch into the detection range, and maintain the wiring integrity of the secondary system during the test. Use the "substation simulation system" to simulate the running status of the tested substation and the direct connection line, use the wireless transmission method to transmit the simulation results to the "collector simulator", and use the scattered arrangement of multiple "collector simulators" to merge to the tested substation Synchronously inject the test signal into the unit, use the "switch simulator" to check the action behavior of the relay protection device, use the network analyzer configured in the secondary system, the fault recorder and the recording function of the ...
