This paper constructs an improved analytical model based on the principle of the protected action and optimizes the solving of its objective function using the improved quantum particle swarm algorithm. The new model not only fully takes into account the false action and refusing action of the protective relays and circuit breakers, the malfunction of protective relays of the circuit breakers and other issues, but also identifies the false and missing alarm of the warning information. The experimental results showed that the improved algorithm not only makes the results of fault diagnosis more accurate but also makes the fault situation shown more clearly. It was conducive to timely recover the fault, while the computing speed and the stability of the model have been further i m p r o v e d .
