摘　　要：提出一种定量分析同步相量测量装置(PMU:Phasor Measurement Unit)可靠性的评估方法,提出并定义定量评估PMU的可靠性指标——PMU的可靠度,针对PMU的各个硬件功能模块建立了相应的可靠性模型,其中全球定位系统(GPS:Global Position System)模块采用了备用模式并建立了Markov状态空间图。以一PMU为例进行计算,结果表明,该方法可有效用于PMU可靠性评估与分析。An evaluation method for WAMS network component reliability was presented. A reliability index of synchronized phasor measurement unit, the reliability of PMU, was proposed and then a suitable reliability model based on the hardware modules was set up. Especially, a Markov state space was built for the GPS module, which is in stand-by mode. Take a synchronized phasor measurement unit for example, the reliatfility index was calculated and the rc, suhs show that this method is effective for the PMU reliability evaluation and analysis.
