摘　　要：针对大电网高压变电站规划的特点,提出一种改进定位策略的顶点加权Voronoi图高压变电站优化规划方法。有效考虑到采用最大空心圆定位策略时空心圆内负荷分布不均匀的情况,提出最大凸多边形负荷定位策略,使高压变电站在合理分布、电网构架趋于合理的同时,更能提高变电站的有效利用率。在考虑地理信息条件等因素对变电站合理选址的基础上,提出基于变电站容量的顶点加权Voronoi图,对高压变电站定容及供电范围进行优化规划,使高压变电站供电区域更加合理。通过某市部分区域的饱和负荷阶段220 kV变电站的优化规划结果表明本文方法对大区域大电网高压变电站规划具有特殊的优势,是对高压变电站优化规划的一种尝试。In view of the characteristics of HV substation planning,this paper proposes a new orientation strategy on the weighted Voronoi diagram used in the HV substation optimization planning.The most greatly convex polygon load orientation strategy was proposed to overcome the complexion of the load asymmetric distribution when using the most greatly air circuit method.This method not only makes the HV substation rationally distributed and power system framework becoming rational,but also enhances the effective utilization of the substations.On the basis of the reasonably site selection of the substation considering the geography information factor,advancing weighted Voronoi diagram was proposed based on the substation capacitance in the optimal HV substation capacitance and service areas planning,which may make the supply region reasonably.The case study of a 220 kV city substations planning in saturated load period proved that the proposed method possesses an especial advantage and is a new attempt in HV substations optimal planning.
