This paper puts forward a new fault diagnosis model based on Petri net.In this new fault diagnosis method,an associated tree is f irst defi ned to describe the logic according to the protections and circuit breakers.After that a Petri net diagnosis model comes into being and the precise diagnosis of power grid elements can be realized at the same time.The simulation results given in this paper illustrate that this fault diagnosis method can make a rapid diagnosis in complex fault situation and give accurate results to power grid fault diagnosis.
This paper puts forward a new fault diagnosis model based on Petri net. In this new fault diagnosis method, an associated tree is first defined to describe the logic according to the protections and circuit breakers. After that a Petri net diagnosis model comes into being and the precise diagnosis of power grid elements can be realized at the same time. The simulation results given in this paper il- lustrate that this fault diagnosis method can make a rapid diagnosis in complex fault situation and give accurate results to power grid fault diagnosis.
