在城镇或农村配网用电增容的环境下，需要增容接入配电变压器，传统就近接入的简单方法有可能会导致配电网电能损耗增加，影响电网电压质量；由此研究了一种基于prim和dijkstra组合算法的配电网负荷接入方法。首先利用prim算法构造拟接入网络的最小生成树，再运用改进的dijkstra算法得到拟接入负荷的次短路径和渐次短路径，同时统筹建设成本综合选出最优路径，用潮流计算验证网络节点电压是否合格；当电压不满足要求时，通过无功二次精确矩计算确定无功补偿点的位置和容量，以实现对电压偏差的修正，且保证配网运行的经济性。以IEEE57节点为实例计算及经济效果评价，验证了本方案的实用性。

With the development of new countryside construction ,and an increasing rural power demand ,the access to specialty transformer and common transformer is widely used .However ,this simple ,traditional nearby access will probably lead to the in‐crease in power distribution loss ,which would influence the stability of network voltage .Therefore ,the study presents an accessing scheme of power distribution network based on prim and dijkstra algorithm to solve this problem .First ,a network access minimum tree is drawn by using the prim algorithm structure .Then ,the best path is obtained by comparison and whether the network node voltage is qualified is verified .If the voltage doesn't meet the demand ,it will be amended by reactive quadric accurate moment ,which can find out the position of reactive power compensation point and capacity .The study states an optimized process of access scheme , and the practicability is also tested through practical calculation and economic effect estimation in this paper .
