VARIABLE SPEED POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve stability of effective power in the case that a power generation generator is synchronously operated in a variable speed power generation system. SOLUTION: The fluctuation component of speed is detected from the power generation generator, and given to the excitation current component of the rotor current of the power generation generator during synchronous operation start. Or an ramp current instruction is given to the torque current component of a rotor current.
