ABSTRACT:
It is an object to supply, to the utmost extent, reactive power according to a demand of a utility grid side while maintaining the power factor within a predetermined range. The wind turbine generator system includes a main controller19. The controller19includes a first controller31performing constant-reactive-power regulation, a second controller32performing constant-power-factor regulation, a judging unit34for judging whether a present operating condition is within a predetermined operating region, and a control-switching unit35for switching from the first controller31to the second controller32when the first controller31is performing the constant-reactive-power regulation and the judging unit34detects a deviation from the operating region.
