一种配电网故障阶段式恢复方法
为快速确定配电网故障恢复的最优方案，提出了一种将启发式规则与优化算法相结合的故障阶段式恢复方法。各个阶段通过指标判定是否执行，不同故障的恢复阶段不同。第一阶段采用启发式搜索方法恢复网络连通性；第二阶段利用和声算法以电压不越限及线路不过载为目标进行重构；第三阶段基于深度优先搜索法及负荷优先级切负荷；第四阶段利用和声算法进行网损优化重构。为快速分析配电网的拓扑结构，提出单联络回路的概念，不仅可用于快速恢复故障后网络的连通性，而且可为优化算法避免拓扑不可行解编码提供理论基础，有效提高了运算效率。通过仿真验证了所提方法的可行性。...

| Abstract_FL | In order to get the optimal fault restoration scheme for distribution network rapidly, this paper proposes a phased distribution network fault restoration method which integrates the heuristic search algorithm with optimization algorithm. Each stage is determined to operate or not through indexes. The restoration scheme of different faults is different. In the first stage, the heuristic search algorithm is adopted to restore connectedness of network;in the second stage, the harmony search algorithm is adopted to restore stability with the objective of voltage and line capacity being within limits;in the third stage, the overload is rejected based on the depth-first search and priority level of load; in the fourth stage, the harmony search algorithm is adopted to reconfigure for minimizing active power loss. For rapid analysis of the distribution network topology structure, this paper proposes single interconnection loop which can be used to restore connectedness of network quickly as well as provide theory foundation of avoiding infeasible solution coding for optimization algorithm, which improves the operation efficiency effectively. The simulation verifies the feasibility of the proposed restoration method. |
