Sneak Timing Analysis based on Time Petri Net in Power System

Sneak timing is an important aspect of sneak circuit. But now there are few researches on special sneak timing analysis in the sneak circuit analysis field. In this paper one method of sneak timing analysis in power system is studied. The systemic time interval which can be gained by the time Petri net model is used to describe the time characteristic of the system. The time Petri net of power system is obtained based on the electrical circuit of system and some characteristics of which are presented. The conditions of the conflictive transitions firing in time Petri net are discussed. Then one way to analyze sneak timing based on time Petri net model is studied. This method is used to analyze the typical sneak timing case in practice successfully which verifies the method is effectual and feasible.
