摘要
Petri网理论具有完善的理论证明依据,是离散动态系统建模的有效工具。该文基于Petri网理论,介绍了一种新的继电保护建模思路。保护装置可以看成一个离散动态系统。利用Petri网中并行、冲突、资源分享等特性,对继电保护中的动作逻辑演化及二次回路动态进行描述,建立了保护装置的PN模型。最后就RCS-901A/B超高压线路成套保护装置进行了工作原理分析和性能评估,证明了所提方法的有效性。
The Petri net is efficient to model DEDS （discrete event dynamic systems）due to its full-developed theories. This paper proposes a method of timed Petri nets for relay schemes modeling. A relay scheme is one of the discrete event dynamic systems. Using the parallel, impacting, resource-sharing characteristics of Petri net, the logic working procedures with secondary loop dynamics are described. The working principle and performance of RCS -901A/B are comprehensively studied and evaluated with the proposed method to demonstrate its effectiveness.
