GENERATING EQUIPMENT USING PERMANENT-MAGNET GENERATOR

摘要

PROBLEM TO BE SOLVED: To efficiently attain robust characteristics over a wide range of variable speed by the reactive power control or voltage control of power converters in generating equipment provided with a permanent-magnet generator. SOLUTION: The generating equipment comprises the permanent-magnet alternating-current generator; a first converter which converts alternating-current power to direct-current power; and a second converter which converts direct- current power transmitted from the first converter to alternating-current power. The first converter is provided with a means for controlling active power and a means for controlling reactive power. The second converter is provided with a means for controlling the voltage of a direct-current system and the reactive power or alternating-current voltage of a power system.
