Abstract Method and apparatus of operating a variable speed power generation system in which the generated output of an induction generator is adjusted by controlling current in the secondary side of the induction generator. Rotation speeds of the induction generator coupled to a prime mover are detected, a secondary current command for controlling the difference between a detected rotation speed and a speed command to zero is generated, and the current in the secondary side of the induction generator is controlled on the basis of the secondary current command. In addition, the generated output of the induction generator is sequentially detected in order that the command value of the speed command is sequentially changed when a detected generated output shows a tendency to increase and, when a detected generated output shifts from an increasing tendency to a decreasing tendency, the command value of the speed command is once changed in the opposite direction against the changing direction up to that time, thereby maximizing the efficiency of the variable speed power generation system and reducing costs.
