| 摘 要： | 为评价二次测量系统故障对一次系统造成的影响,本文在定义“能量信息”系统场景集基础上,将WAMS故障考虑在系统故障中,从故障结果与操作盲区对WAMS故障时的电力系统故障进行了非正常运行状态可观性分析,并结合系统失供电率指标EDNS,构建了一、二次复合系统的综合可靠性评估模型。基于蒙特卡洛仿真计算结果发现:WAMS故障对电力系统的影响十分明显,且不容忽视,通过PMU的冗余配置可以改进WAMS可靠程度,对提升电力系统整体可靠性有着显著意义。

| Abstract: | To assess the influence of secondary measuring system faults on primary system, wide-area measurement system faults are considered in system faults based on the definition of “power-information” system scenario set. The observability of abnormal condition is analyzed for WAMS faults. By combing with the index of loss rate of power supply EDNS, the comprehensive reliability evaluation model of primary and secondary system is built. Based on Monte Carlo simulation, the results show that WAMS faults have great impact on power system and can not be neglected. Through the redundant configuration of PMU, the reliability degree is modified, which has great significant for improving the reliability of whole power system. |
