Abstract: Disclosed are a system and a method for controlling a voltage at a common coupling point of a wind power plant. An embodiment of the present invention provides a method for controlling a voltage at a common coupling point of a wind power plant including a plurality of wind generators, including the steps of: calculating a first voltage error value which is a difference between a real voltage at the common coupling point and a reference voltage of the common coupling point by a first calculator of the control device of the power plant; calculating a compensation reference voltage based on the first voltage error value by a first controller of the control device of the power plant; calculating a second voltage error value by subtracting a voltage at an output terminal of the power generator from a sum of a generator reference voltage and the compensation reference voltage by a second calculator of the control device of the power generator; calculating a reactive power compensation value corresponding to the second voltage error value by a compensation controller of the control device of the wind generator; and injecting reactive power corresponding to the reactive power compensation value to a system side by a converter of the wind generator.
