Abstract
The main current research achievements for power system diagnoses are summarized, a practical power grid fault diagnosis method base on China's power grid actual is proposed in this paper. Through the analysis of the power flow difference between normal operation and fault tripping, a fault equipment confirmed algorithm based on abnormal changes in the structure of power grid is developed, the evaluation of the action of the related relay protection and circuit breaker is realized by taking the confirmed fault equipment as the beginning of logic analysis.
