Abstract

Due to large-scale wind farms connected to the grid, so when the grid computing need to consider the impact of wind farm integrated into the power grid. Paper firstly analyzes the model individual wind turbine. Analysis of the resistance Crowbar access to wind turbine model and the number of wind turbines running impact on the positive and negative sequence impedance, obtained wind turbine positive and negative sequence impedance calculation formula in the large and small operation mode. Then according to the actual connection of wind farms, bearing in mind impact of the transformer access, wind generators and transformers series equivalent to a wind chassis variant group. Finally, to Calculate the equivalently impedance according to the actual parameters of wind farms, and to verify the accuracy of the results calculated by the fault.
