摘要： In a control apparatus for a wind turbine generator system, a wind turbine classifying unit classifies a plurality of wind turbines into a first wind turbine group that does not satisfy a rated wind speed condition and a second wind turbine group that satisfies the rated wind speed condition. A first controlling unit releases, for the wind turbines of the first wind turbine group, the output power reducing operation and causes the wind turbines of the first wind turbine group to perform an output power corresponding to a wind condition. A second controlling unit supplements a first deviation, which is a difference between a total output power of the first wind turbine group and a target output power, with an output power from the wind turbine of the second wind turbine group.

摘要： A wind turbine generator generates power through rotation of a rotor to which a plurality of blades are pivotally coupled and includes a pitch-angle control section that outputs a pitch-angle command value that indicates the amount of change in the pitch angle of each of the blades, hydraulic cylinders each of which changes the pitch angle of the corresponding blade based on the corresponding pitch-angle command value output from the pitch-angle control section, and load measurement sections that measure blade-root loads. A set value indicating that wind received by the wind turbine generator has a biased wind speed distribution is set in advance in the pitch-angle control section. Only when a calculated pitch-angle command value exceeds the set value, the pitch-angle control section outputs a pitch-angle command value beyond pitch command limit values. Therefore, in the wind turbine generator, a higher load than necessary is not imposed on a drive unit for the pitch angle of each of the blades in a case of a normal wind speed or a wind speed distribution caused by the normal wind speed, and the blade-root load can be sufficiently reduced even in a case of a wind speed distribution that occurs when a strong wind is received.
摘要翻译：风力涡轮发电机通过旋转多个叶片枢转地连接的转子产生动力，并且包括俯仰角控制部分，其输出表示每个叶片的俯仰角的变化量的俯仰角指令值叶片，液压缸，其各自根据从俯仰角控制部输出的相应的俯仰角指令值和测量叶片根部载荷的载荷测量部，改变对应叶片的俯仰角。在俯仰角控制部中预先设定表示风力发电机接收的风具有偏置的风速分布的设定值。只有当计算出的俯仰角指令值超过设定值时，俯仰角控制部输出俯仰角指令值超过俯仰指令极限值。因此，在风力发电机中，在由正常风速引起的正常风速或风速分布的情况下，不对每个叶片的俯仰角的驱动单元施加比所需的更高的载荷，即使在收到强风时发生的风速分布的情况下，也可以充分降低叶片根负载。

摘要： A wind turbine generator includes a synchronous generator that generates electric power via rotation of a rotor provided with blades that receive wind and that supplies the generated electric power to a utility grid, and a sea water resistor in which sea water serves as a resistive element. When the output power of the synchronous generator drops suddenly because of a momentary power interruption caused by a fault occurring on the utility grid, thus producing surplus energy, the sea water resistor consumes, in the form of electric power, the surplus energy that cannot be supplied to the utility grid from among the electric power generated at the synchronous generator. Because the sea water resistor uses sea water as the resistive element, the problem of heat generation hardly ever arises, and because the sea water can be easily exchanged, it is not affected by lifetime or on-time limitations.
