[0029] The above-mentioned secondary control loop may refer to a control system structure used to monitor and adjust faults or abnormal conditions in a power system. In a power system, a secondary control loop is a second control based on a primary control loop, which is used to more finely monitor and adjust various parameters in a power system. A secondary control loop may be composed of protection equipment, monitoring instruments, fault detectors, etc., which may detect and handle faults, overloads, short circuits, and other problems in a power system in a timely manner to ensure safe and stable operation of the power system.

The anti-malfunction locking loop can be used to control key equipment or systems, such as motors, valves, etc., to prevent dangerous situations caused by misoperation or failure.

Only under specific logical conditions can the equipment work; delaying the start or stop of the equipment by setting a time delay or requiring multiple confirmations to prevent misoperation. By combining the above multiple methods, a multiple anti-malfunction locking loop can be constructed to ensure that the equipment or system will not malfunction under specific conditions, thereby improving the safety and reliability of equipment operation.

Specifically, the verification function simulation module can verify the action of the knife switch by simulating operation conditions in various actual scenarios. For example, when simulating a short circuit in the power system, the knife switch should be able to disconnect the circuit in time to prevent damage to the power system. The verification function simulation module can also simulate different types of fault conditions, such as overload, overcurrent, etc., so that the knife switch can correctly identify and take corresponding measures. By verifying and fault handling drills of the knife switch, it can be ensured that the equipment can work reliably in actual operation, thereby improving the safety and stability of the power system.
