静止无功补偿器作为一种无功功率设备，对电力系统的可靠性和安全性起着重要的作用。在传统的可靠性评估中，无功功率只是作为一个网络约束来分析，现有的可靠性技术中没有考虑SVC对系统可靠性评估的影响。本文首先分析了SVC各组成部分对系统可用度的影响，并针对典型SVC提出了可靠性模型。其次，马尔可夫过程分析所提出的模型，并提出了一个等效的三状态模型的SVC。然后，在一个实际的操作点进行灵敏度分析，考虑不同的组件的故障率和修复率对系统的可用度的影响。(C)2013爱思唯尔有限公司保留所有权利。
Static VAr compensator as a reactive power equipment plays a significant role in power system reliability and security. Because in conventional reliability evaluations, reactive power had only been considered as a network constraint in analysis, the effect of SVC on reliability evaluation of the system has not been considered in the existing reliability techniques yet. This paper, at first, analyzes the role of different components of SVC in availability of the system, and proposes a reliability model for a typical SVC. Next, Markov process is employed to analyze the proposed model and to present an equivalent three state model for the SVC. Then, a sensitivity analysis in a practical operating point is carried out to consider the impact of the failure and repair rates of different components on the availability of the system.
