| 摘 要： | 为确定复杂环网保护配合中的最优断点集,引入了4个指标作为最优断点寻找的评判依据,建立了寻找最优断点集的数学模型。基于细菌群体趋药性算法的基本原理,提出了计算最优断点集的新方法。较已有的计算断点集方法,所述方法可以快速地找出最优的最小断点集。算例分析证明了该方法的有效性和实用性。

| Abstract: | In order to determine the optimal break point sets(OBPSs) for protection coordination in multi-loop network,four indices are introduced as the judgment criterion of OBPSs,the math model looking for OBPSs is developed.Then,based on the principle of bacterial colony chemotaxis algorithm,a new method of determining OBPSs is presented.Comparing with the existing method,the proposed method can find the optimal minimum break point set.An example analysis proves that this method is valid and applicable. |
