[0074] The present invention will be further described in detail below in conjunction with the drawings.
[0075] The present invention provides a method for controlling reactive power at a grid connection point of a wind farm. The specific flow chart is as follows figure 1 As shown, the specific process is as follows:
[0076] S101: Determine the voltage deviation of the grid connection point of the wind farm according to the control mode of the wind farm;
[0077] S102: Determine the reactive power distribution coefficient of the wind turbine according to the actual value of the reactive power of the wind turbine;
[0078] S103: Determine the reactive power reference value of the wind turbine based on the voltage deviation of the grid connection point of the wind farm and the reactive power distribution coefficient of the wind turbine.
[0079] According to the control mode of the wind farm, the voltage deviation of the grid connection point of the wind farm is determined, and the sp...
