Therefore, according to the abnormal event data set constructed by the model analysis unit, the processing strategy for protecting the system abnormality can be determined. The primary equipment cannot run without protection, namely when the protection system with double configuration is abnormal and cannot work normally, the circuit breaker connected with the primary equipment must be disconnected; if the breaker fails, the protection trip cannot effectively isolate the fault, and the failure protection of the breaker must be started to trip off the adjacent breaker to isolate the fault; if the abnormal conditions of different protection systems can cause the failure protection of the circuit breaker to be unable to start, the circuit breaker must be out of service. If the first set of line protection is abnormal, the second set of bus protection is abnormal, and the two sets of protection trips point to the same circuit breaker. If the two sets of line protection faults trip when the line is in fault, and if the circuit breaker fails, due to the fact that the second set of protection of the bus is abnormal, the disconnection fault point of the adjacent circuit breaker cannot be isolated through bus protection; and fourthly, the bus protection in a double-bus connection mode is in outage, because the bus is connected with a plurality of primary elements (such as circuits and transformers), the bus can not be stopped generally, and the action time of the opposite-side line protection or the backup protection of the transformer protection without the bus differential protection bus is shortened.
