摘　　要：地区电网的故障恢复是一个多目标、多约束、复杂的优化问题,其优化的效率是其能否在线应用的关键。对地区电网故障恢复的实用化进行了研究,构建了一种用于故障恢复处理的电网分析模型,提出了一种面向在线应用的改进型最小生成树故障恢复处理算法。该算法在对复杂地区电网进行模型化的基础,根据模型中子系统当前属性和即时路径权值,动态调整最小树的搜索范围和生长方向,从而实现最优恢复路径的快速搜索。实际电网故障恢复事例已证明,本算法能够实现地区电网故障最优恢复路径的快速搜索。Fault restoration on regional power grids is a multi-objective,multi-contrained and complex optimization problem,and its efficiency of optimization is the key to its application on line.After studying the application of fault restoration technologies on regional power grids,a n analytical model for on-line fault restoration is built and an improved Minimum Spanning Tree algorithm is presented.B ased on modeling of the complex regional power grids,the algorithm can dynamically adjust searching space and growing direction of the minimum spanning tree according to the current properties of the subsystem and the present weight of the path in the analytical model to carry out the on-line quick search of the optimal restoration path.T he validity of the algorithm has been verified by practical cases of fault restoration.
