    • PROBLEM TO BE SOLVED: To provide a method and an apparatus for controlling the operation of a wind turbine generator system wherein a variable speed operation range can be expanded over an entire wind speed range from a low wind speed range in which the induced voltage of a generator is lower than a voltage required on the power consuming system side to a high wind speed range in which the wind speed is equal to or higher than a rated wind speed through a simplified control circuit with a minimized number of switching elements.
      SOLUTION: The operation controlling means is for wind turbine generator systems. According to the numbers of revolutions of a wind turbine and a generator, it divides the operation mode of the wind turbine and the generator into three speed control modes: low wind speed control mode in which the induced voltage of the generator is lower than the voltage required on the power consuming system side; high wind speed control mode in which the wind speed of the wind turbine is equal to or higher than the rated wind speed; and intermediate wind speed control mode in which the wind speed is between the wind speed in low wind speed control mode and the wind speed in high wind speed control mode. In low wind speed control mode, a step-up chopper circuit for increasing the voltage of the generator is activated. In operation mode in which a certain value is exceeded, the operation of the step-up chopper circuit is stopped.

SOLUTION: This system is composed of a group of thyristors 2 which are interposed between a wind power generator 1 and a power supply system, a pitch angle controller 26 which controls the pitch angle of the variable wing of a wind mill, and a gate angle controller 32 which controls the gate angles of the group of thyristors 2.

The pitch angle increases slowly and surely, according to the specified numerical increment, and such a certain pitch angle increase can control the magnitude of a rush current into a sufficiently small value, and the control is certain.
