Fault Diagnosis of Complex Electric Power System Using the Improved Grey Incidence Degree Model

The fault diagnosis of complex electric power systems in marine is very complex and hard, in order to prohibit or further reduce the misoperation after the faults occurring of complex electric power system, the model based on weighted degree of grey incidence of optimized entropy and fault diagnosis system are proposed in this paper, and some simulation experiments about the typical faults of complex electric power system are conducted. And the results show that the system is more stable and its conclusion is right and can satisfy diagnosis in real time, and higher faults subjection degrees resolving power can be achieved. So a novel means is provided for the diagnosis of the fault in complex electric power system.
