摘要
在Ｍａｒｋｏｖ过程、累积状态之间的转移频率以及ＦＤ法的基础上，根据主接线的接线方式和运行条件， 研究了断路器等元件的可靠性等效模型，并在对系统从电源端到负荷端求解的过程中应用了“状态节点”的概 念以避免“状态灾难”。通过对广州２００ｋＶ变电站电气主接线的各种运行方式进行深入分析，应用本文提出的 模型、算法和评估软件进行可靠性评估和综合分析，验证了此方法的正确性和有效性。
Based on the Markov Processes, the transitional frequencies between cumulative states and the FD methods, the reliability equivalent models of components such as circuit breakers are studied in this paper according to the operation conditions and connecting schemes of substation bus arrangements. The concept of 'state node' is applied to prevent the 'state disaster' problem progressively from the sending end to the receiving end. All operation conditions of 220 kV substation bus arrangements of Guangzhou are analyzed in detail. With the model, algorithm and program proposed in this paper, the reliability evaluation and comprehensive analysis show that the method is correct and effective.
