| 摘 要： | 建立了继电保护原理性运行失效的双层概率模型,即基于赋时Petri网的保护逻辑动态层和基于模糊Petri网的概率信息层。该模型不仅能够进行保护逻辑的动态仿真,而且能够根据系统运行方式、保护定值和保护逻辑,定量计算保护系统运行过程中由继电保护原理引起的运行失效概率,对继电保护动作特性与特定故障匹配程度的随机性分析具有参考价值。

| Abstract: | A two-level operation failure probability model for power system protection is proposed.This model is based on programmable time Petri net(PTPN)for dynamic simulation of protection logic,and fuzzy Petri net(FPN)for probability calculation.It can be used to simulate protection logic as well as to calculate instantaneous failure probability for protection design purpose according to the system operation mode,protection settings and protection logic.It provides a useful reference for the analysis of the probab... |
