| 摘 要： | 介绍了用模糊数学计算发电系统可靠性的一种新方法。该方法用隶属函数表现发电机组故障率和修复率的不确定性和不精确性，将系统负荷数据“模糊化”，同时在机组追加算法的基础上进行模糊修正，通过负荷的模糊聚类简化计算，提高了计算效率。该算法以概率分布特征表述可靠性指标，符合概率统计特征。

| Abstract: | A new method for calculating generating system reliability using fuzzy mathematics is persented here. In the reliability evaluation of power systems,a membership function can be provided to represent the uncertainties and inaccuracies in the failure rates and repair rates of generating units. The basic unit addition recursive algorithm is modified. Loads are represented as clusters to overcome the difficulty of large computational time requirements. The efficiency of calculation has been raised. The calculation method has used the probability distribution chart to describe the reliability. It is con- formed to the probability statistic characteristic. |
