State sequence simulation method for realizing multi-source abnormal working condition coupling of power system

The invention discloses a state sequence simulation method for realizing multi-source abnormal working condition coupling of a power system, and the method comprises the steps: adding simulatable data sources in a state sequence through an abnormal source registration mode; superposing the registered system transient fault data information into the steady-state electrical quantity output data through a data coupling mode; and coupling the composite fault electrical quantity output data, the switching value data information and other abnormal source data information into a time sequence beat sequence in a time sequence coupling mode, and simulating the power system fault in a state sequence mode. According to the invention, various transient faults, auxiliary equipment faults, communication signal faults and other abnormal working conditions of the composite power system of the power system can be simulated through a single device, a simulation system is not needed, the test efficiency is high, and the practic
