Title:
POWER GENERATOR SYSTEM, CONTROL METHOD FOR POWER GENERATOR SYSTEM, AND CONTROL METHOD FOR COMPOSITE POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/044014
Kind Code:
A1
Abstract:
Provided are a power generation system and a control method therefor that can realize high efficiency and widen an output adjustment range in accordance with operating conditions such as load fluctuations, the atmospheric environment, and fuel conditions, in a composite power generation system constituted by a reciprocating engine power generator and a variable power source such as that of solar power generation or wind power generation. The present invention is characterized: by comprising a reciprocating engine, an alternating-current excitation power generator that is connected to an output shaft of the reciprocating engine, and a power converter that is connected to a rotation shaft of the alternating-current excitation power generator via a slip ring and supplies alternating-current power to a rotor of the alternating-current excitation generator; and in that the rotation speed and torque of the reciprocating engine are controlled via slip frequency control of the power converter.
