摘要： The present disclosure is related to a power control apparatus and a method for controlling power, more specifically to a power control apparatus that controls the risk of overcurrent in a power generator when the voltage in the power grid is low. In accordance with an embodiment of the present disclosure, a power control apparatus that controls power in a power generation system including a generator generating power can include a current comparator, which calculates an error current by using a difference between a current measured at the generator and a rated current of the generator, a controlling unit, which calculates a real power value by receiving the error current and outputs a switch driving signal corresponding to the calculated real power value, a switch, which is operated by the switch driving signal, and a resistance device, which is coupled to the switch to consume the error current.

摘要： A pitch control apparatus for controlling the pitch value for a wind power generation system includes a generator comparing unit that calculates an error signal based on a difference between a generator measurement signal corresponding with an operation of the power generation system and a generator reference signal, and a reference pitch calculating unit that calculates a reference pitch value using the error signal. The pitch control apparatus further includes a compensation pitch calculating unit that calculates a compensation pitch value using an error value from the wind power generation system and a pitch calculating unit that calculates a pitch value using the reference pitch value and the compensation pitch value. The error value may be any one of a voltage error value from a direct-current capacitor, a voltage error value from a grid connection point, a speed error value from a rotor, and a frequency error value from a grid connection point.
