This article proposes a method of reactive compensation based on the flow calculation in view of the 10kV distribution network. Because of actual operation of the distribution network,three load's ways which are the maximal,the minimum and the general one are considered. Under the minimum load's ways,initial compensation scheme,including initial compensation sites and their capacities,is decided with the methods of the conventional flow calculation and reactive quadric accurate moment for the purpose of decreasing the net loss. According to the voltage qualified rate,the initial compensation scheme is adjusted to improve the voltage qualified rate. Through the iteration,the overall voltage qualified rate achieves the request. It's tested on experimental systems of 19-node distribution lines,and the results are satisfying,which confirm the reasonableness,convenience and practicality of presented method.
