Abstract：Considering charging power of submarine cable of wind farm influences the bus voltage , this paper points out that there is a lower limit of output of wind farm . The analysis and calculation of different reactive compensation mode, the relationship between the lower limit of the compensation capacity and the output of wind farm . this paper uses the method of steady state power flow simulation to determine the lower limit of wind farm under different ways of output. When the leading power factor operation adopts a wind farm, the absorption of charging power of submarine cable, reactive power compensation device of high resistance and coordination can satisfy the voltage does not cross the border conditions, reduce the lower limit of wind power grid, participate in making the regulation of wind farm better.
