| 摘 要： | 推导了系统电量不足期望对元件故障概率的敏感度的计算公式解,引入了元件敏感度定义,筛选出敏感度指标大的元件集合,使用交流潮流算法,组合计算电力系统的可靠性指标,提出了利用元件敏感度分析对系统元件进行排序,从而获得关键元件信息进而进行电力系统可靠性指标的REAUSA组合计算。在计算速度上取得了突破性的进展,缓解了电网可靠性指标计算的“计算灾”问题,为研究电网可靠性评估算法提供了一种新思路。

| Abstract: | The definition of element sensitivity indices is presented. The REAUSA (Reliability Evaluation Algorithm by Using Sensitivity Analysis) algorithm is proposed, The information of power system sensitivity is applied to reliability parameters of components of the electric network to get the information of key components and to combine the reliability indices of power systems. The great progress in speed of evaluation is achieved. The "calculation catastrophe" of the reliability evaluation of power systems can be alleviated. A new idea for studying electrical reliability algorithm is provided. |
