This article analyzed the mechanism of voltage fluctuation caused by the distributed access to network of the wind turbine generator. Based on the actual control logic of wind turbine,a voltage control method of wind turbine distributed access was proposed. Using MATLAB software s-function simulation environment it set up a simulation model based on the actual control structure and carried out the field measurement on a project. The results of simulation and test show that the control algorithm can effectively stabilize the voltage of the distribution network.
