Abstract: PURPOSE: A PLL(Phase-Locked Loop) controller using feed-forward is provided to improve the responsiveness of phase angle estimation by estimating disturbance-resistant phase angles. CONSTITUTION: A PLL controller(100) includes a two-phase signal generator(110), a d-q converter(120), a loop filter(130), a feed-forward controller(140), and a feed-forward calculator(150). The two-phase signal generator converts the system voltage to two-phase voltages on a stationary frame. The d-q converter converts the two-phase voltages on the stationary frame to two-phase voltages on a rotating frame. The loop filter calculates a real phase angle of the system voltage by applying a gain value to the d-axis voltage among the two-phase voltages on the rotating frame. The feed-forward controller receives the two-phase voltages on the rotating frame and calculates a reference phase angle of the system voltage. The feed-forward calculator feed-forwards the reference phase angle to the real phase angle and calculates a final estimated phase angle.

Abstract: PURPOSE: An exciter controller capable of using the amount of current change of the exciter as a feed-forward term is provided to pull the current command value and regularly control the output power. CONSTITUTION: A voltage comparative unit(111) outputs the voltage error of the command value voltage of a generator and the real voltage. A command value current controller(112) outputs the voltage error by calculating into the command value current of the exciter. A feed-forward controller(113) outputs the amount of current change as a feed-forward term. A current comparator(114) outputs the difference value of the real current of the exciter as the current error. A driving current controller(115) outputs by calculating as the driving current of the exciter.
