摘要： A controller for plural wind power generators (10) improves power generation output in a wind farm (100) and reduces damage to a blade or the like of the wind power generator. The controller has a calculation unit that calculates a rotational speed command value, a torque command value, or a yaw angle command value for the plurality of wind power generators 10a and 10b, using measured wind condition information, so as to obtain total generated power generated with the plurality of wind power generators 10a and 10b, higher than total generated power obtained by control to obtain maximum generated power generated with a wind power generator 10a on the windward side, and so as to make any damage to the wind power generator on the windward or leeward side or total damage to the wind power generator 10a or 10b on the windward or leeward side, lower than damage or total damage received by the control to obtain the maximum generated power generated with the wind power generator 10a on the windward side. The controller controls the respective wind power generators (10) based on a result of the calculation.
