진동수주형 파력발전시스템을 위한 전력변환장치에 관한 연구

Abstract

An oscillating wave column (OWC) wave power generation system consists of an OWC chamber, a turbine, a generator, and a power converter. The power converter is composed of a rectifier and an inverter. The rectifier converts the three-phase output voltage from the generator to dc voltage while controlling efficiency and rotor speed of the generator. The inverter converts the rectified dc voltage to ac voltage with appropriate frequency and amplitude required by the grid. This paper presents a topology of the power converter for OWC wave power generation as well as mathematical modeling of a permanent synchronous generator and power converter to carry out dynamic simulation of power conversion system.
