Research on One-Key Sequence Control Automatic Test Technology Based on Digital Simulation

In order to address the issues with the current acceptance testing of “one-key sequence control” and apply it to the joint debugging testing of “one-key sequence control” between the main and sub-stations, this paper proposes a “one-key sequence control” automatic test method based on digital simulation. Based on the general template, quickly build a one-key sequence control configuration library, and complete the instantiation of equipment state, operation ticket, and five-proof logic configuration based on semantic recognition, simulate the actual primary and secondary equipment of the interval layer through digital simulation and modeling, realize remote signal, telemetry, remote control simulation, and at the same time simulate the centralized control main station, control the sequence control host to call, rehearse, and execute the operation ticket, realize the positive and negative logic closed-loop automatic test for “one-key sequence control”, cooperate with the completion of the “one-key sequence control” main and sub-station joint debugging test, for the “one-key sequence control” system test, The acceptance work provides efficient and reliable technical methods to ensure that the “one-key sequence control” technology can be safely and reliably applied to substation engineering.
