基于动态故障树的变电站通信系统可靠性分析
Reliability Analysis of Communication Systems in Substation Based on Dynamic Fault Tree
摘要
Abstract
On the basis of studying the mechanism of parallel redundancy protocol (PRP), high availability seamless ring (HSR) and rapid spanning tree protocol (RSTP) protocols used in the substation communication systems, a method that can quantitatively assess the reliability of a substation communication system was proposed to provide the reference for the selecting ways of substation communication systems based on IEC 61850. At the aspect of repairable feature and redundancy, the reliability models were constructed applying dynamic fault tree (DFT) modeling method. The modularization design was utilized to divide the dynamic fault trees into static and dynamic subtrees. The static tree was solved with binary decision diagram (BDD) and the dynamic tree was solved with Markov method. The analysis results of the reliability indices and model structures of the three repairable networks show that PRP network possesses the highest reliability among three networks and its cost is also the highest in repairable system.关键词
