Boost 컨버터와 계통연계 인버터를 이용한 풍력발전의 센서리스 MPPT 제어

초록

This paper proposes the control method of maximum power point tracking for the wind energy generation system using the duty ratio control of boost type DC-DC converter. For a lower cost and a higher reliability, the wind and the generator velocity sensors are removed. The boost converter duty switching performs MPPT(maximum power point tracking) control. Chain rule is applied by using each function. the grid side inverter is controlled to regulate unity power factor. Proposed control method was analyzed mathematically and tested by the computer simulation using Psim.
