变电站主接线可靠性评估的逐次 FD 法

Stepwlse FD Method for Reliability Evaluation of Substation Bus Arrangement

本文在应用Ｍａｒｋｏｖ过程的基本理论对变电站主接线进行可靠性评估的基础上，利用累积状态之间的转移频率的概念，根据主接线的接线方式和运行条件，探讨了一种克服“状态灾难”的逐次ＦＤ法。在对系统从电源端到负荷端逐次运用Ｍａｒｋｏｖ过程求解的过程中引入了“状态节点”的概念。最后给出一个实例分析。

In the process of reliability evaluation for substation bus arrangement using the basic Markov Processes Theory, with the concepts of transitional frequencies between cumulative states, an improved Frequency & Duration (FD) Method to prevent 'States Disaster' is discussed in this paper according to the operation conditions and connecting fashion of the substation bus arrangement, and the concept of 'statenode' is presented to solve the problem progressively from the sending end to the receiving end. A practical example to support it lies at the end.
