    摘要： A method of controlling an operation of a wind power generation system provided with a plurality of wind turbines, in which output power of each wind turbine is supplied to an electric power system through a common interconnection node where output data of each wind turbine is obtained, where a periodic correlation between output fluctuations of adjacent wind turbines is determined by using the output data, the correlation is determined as a strong correlation when the correlation is more than two times greater than an average level of the correlation, and a phase of the output of either one of the adjacent wind turbines is shifted by a period of the strong correlation.

    摘要： Provided is a wind power generation system intending to suppress an increase of torque when a voltage in a utility grid is restored, and to reduce a load to devices due to the torque. The blade control unit controls the pitch angle of the wind turbine blades such that a rotation speed of the power generator becomes equal to or greater than a synchronous rotation speed when the power control unit de-actuates the operations of the converter and the inverter, and controls the pitch angle of the wind turbine blades such that the pitch angle matches a target pitch angle that is determined based on one of a wind speed, a rotation speed of the power generator, and a requested output power when the power control unit re-actuates the operations of the converter and the inverter.

    摘要： An object is to improve the operating rate. A first switch is provided in a power line connecting a power generator to a power system, and a second switch that can be opened and closed by remote control is provided in the power line between the power generator and the first switch. In the second switch, a withstand current capability is set that allows current flowing in a low-voltage event and that withstands current having a value equal to or less than a current value specified by the thermal setting of the power generator. In the first switch, a withstand current capability is set that is superior to the withstand current capability of the second switch and that withstands current having a value equal to or less than the current value specified by the thermal setting of the power generator.
