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 wind power generation device is provided with a blade control unit 22 configured to control a pitch angle of wind turbine blades. The blade control unit 22 controls the pitch angle of the wind turbine blades such that a rotation speed of the power generator 6 becomes equal to or greater than a synchronous rotation speed when the power control unit 21 de-actuates the operations of the converter 14 and the inverter 16, 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 6, and a requested output power when the power control unit 21 re-actuates the operations of the converter 14 and the inverter 16.

摘要： A wind turbine generator system includes: a wind turbine rotor including a blade having a variable pitch angle; a generator driven by the wind turbine rotor; and a control unit controlling the output power of the generator and the pitch angle of the blade in response to the rotational speed of the wind turbine rotor or the generator. The control unit performs a first control in which the output power is controlled in accordance with a predetermined power-rotational speed curve until the rotational speed is increased to reach a predetermined rated rotational speed, and performs a second control in which the output power is controlled to a predetermined rated power when the rotational speed exceeds the rated rotational speed; the control unit is responsive to the pitch angle for maintaining a state of performing the second control is or for switching to a state of performing the first control, when the rotational speed is reduced below the rated rotational speed after the control unit is once placed into the state of performing the second control.

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.

摘要： A wind power generator system according to the present invention includes: a windmill rotor including a blade having a variable pitch angle; a generator driven by the windmill rotor; and a control unit controlling the output power of the generator and the pitch angle of the blade in response to the rotational speed (É) of the windmill rotor or the generator. The control unit performs a first control in which the output power is controlled in accordance with a predetermined power-rotational speed curve until the rotational speed (É) is increased to reach a predetermined rated rotational speed, and performs a second control in which the output power is controlled to a predetermined rated power when the rotational speed (É) exceeds the rated rotational speed; the control unit is responsive to the pitch angle for maintaining a state of performing the second control is or for switching to a state of performing the first control, when the rotational speed (É) is reduced below the rated rotational speed after the control unit is once placed into the state of performing the second control. This provides a wind power generator system which suppresses output power fluctuation and generation efficiency reduction when a transient wind null occurs.
