Abrégé
(EN)
In the present invention, a wind power plant control device (54) is provided to a wind power plant (50) having a plurality of wind energy conversion devices, and in a case where the electric power provided from the wind power plant (50) to a power grid is caused to be reduced, from among the plurality of wind energy conversion devices, the wind power conversion device for which the actual amount of electrical power being output is relatively small with respect to the maximum electrical power the wind power conversion device is capable of outputting is caused to perform output reduction control by reducing the output and at the same time increasing the rotation speed of rotors. With this configuration, even if control is performed to reduce the output of a wind power conversion device, the wasting of the wind energy received by the blades can be suppressed and the total yearly power generation amount can be increased.

风力发电站控制装置(54)设置在具有多个风力发电装置的风力发电站(50)中,当降低从风力发电站(50)到电力系统的供电时,使多个风力发电装置中,实际输出的电力相对可输出的最大电力较小的风力发电装置降低输出,并且进行增加风轮的转速的输出降低控制。由此,即使进行使风力发电装置降低输出的控制,也可抑制舍弃叶片接受的风能的情况,增加的年度总发电量。
