The Petri Net's Simplified Technology & It's Application For Power System Fault Diagnose

Petri net is a powerful tool for modeling and analyzing systems.It is widely used in a lot of kinds of fields. But there is a problem which bars Petri net development: too much nodes lead to"station explosion",specially when analysing a large and complicated system. How to simplify the Petri net is always an important task for the petri net researchers .It is a useful simplifying way to decompose the petri net.Fault diagnosis of power system is an important stage of the automation of electric power system .The Fault diagnosis of power system basing on Petri net has a good prospect.This test discusses the union decomposition techenoly of Petri net ,and puts forward a way to decompose the net with no loop,multi-output, and applies this way in the fault diagnosis of power system.Therefore it gives a feasible way for the large and complicated system's fault diagnosis.Using this way,this test designs a simulating,visual software for a 10KV distribution with VC++.
