摘要
电气装置的防误闭锁是实现电网安全运行的重要环节。利用Petri网建模具有直观性、逻辑严密性的特点,可将其用于电网防误闭锁系统的建模。着重研究了防误系统的建模方法和主要算法,分析了防误闭锁功能的实现过程,并给出电网运行方式变化时模型的快速修正方法。算例结果表明,Petri网是一种有效的防误闭锁建模工具。
Anti-misoperation lockout of electrical devices is the key to operation safety of power grid. Petri netmodeling is characterized by its intuitiveness and logicalness,so it is used for modeling of anti-misoperationlockout system for power grid. This paper lays emphasis on research of modeling methods and major algo-rithms;it analyzes the implementation of anti-misoperation lockout and proposes rapid correction method ofthe model when the operating mode of power grid is changed. The numerical result shows that Petri net is aneffective modeling tool of anti-misoperation lockout.
