In view of such situation that the reactive power voltage control of existing distribution network is difficult to meet voltage regulation demand of the distribution network in case the lack of control equipment resources. In this paper

a kind of voltage control method of distribution network based on active load transfer is proposed on the basis of typical wiring structure and voltage control analysis of the distribution network. This method takes the highest qualification rate of the line node voltage in the time period as the objective function.. The voltage control model of active load transfer is established

the calculation of the model is made by the equation extension of the model so to keep the line voltage within qualification range.The traditional control method and the method proposed in this paper is compared by simulation with ring network line of real distribution network as an example

the effectiveness of the proposed method is verified by the result

showing that the method has superiority in such aspects as energy saving and loss reduction as well as voltage quality control etc.
