Therefore, the switch logic of the auxiliary switching system is simulated.
It can be seen from the foregoing technical solutions that, this embodiment provides a switch simulation system, which includes at least one switch simulation module, where each switch simulation module includes an input interface, a switch logic module, and an output interface. The switch logic module is used for receiving a plurality of switch control commands and outputting the switch control commands to the switch interface; the switch logic module is used for carrying out logic operation on the switch control commands based on preset switch logic to obtain switch-on position information and/or switch-off position information.

The technical scheme provided by the application has the following characteristics:
the core simulation part is completed by software logic, so that the simulation system can simulate the opening and closing positions of the circuit breaker in the switch cabinet; simulating the working/testing position of a handcart in the switch cabinet; and (4) switch-on and switch-off position simulation of a grounding switch in the switch cabinet.
And the opening and closing time of the flexible operating mechanism is as follows: the method is realized by modifying a timer in logic according to the definition of the operation time of a field actual mechanism; the device can be matched with an OMICRON protection tester to simulate the voltage and non-voltage states of each incoming line and each bus according to the position state of each switch of the simulated primary system.
Compared with the existing market simulation products, the system can save the fixed asset cost of the laboratory and reduce the occupied laboratory area; the on-site debugging time of the power load switching system is greatly saved, and most of the debugging can be completed before delivery, so that the on-site debugging can be ensured to pass once without repeated tests; the logic or the switch sequence control logic of the power load switching system can be fully debugged, and the logic hidden danger is eliminated; on-site equipment matching is not needed, so that the debugging cost (such as repeated starting and stopping of the oil engine) can be greatly saved;
therefore, the system has the advantages that:
the configuration is flexible: the simulation of the transformer substation of various primary system frameworks/various incoming and outgoing lines with different quantities can be completed;
the expansibility is strong: for a transformer substation with more inlet and outlet lines, the two systems can be expanded to be simulated together; the system may be implemented using a single cabinet as shown in fig. 6.
Can integrate: the device can be integrated into an existing automatic switching system of a transformer substation (such as Easergy A5 of Schneider), and is used as a part of an automatic switching product to provide total-station simulation, so that the field debugging of the switching system and the training/maintenance of a switching system by a later-stage user are facilitated.
