조류발전을 위한 MPPT제어 방법

초록

In this paper, the control method of maximum power point tracking(MPPT) using the duty ratio control of buck-type dc/dc converter is presented for seaflow generation system. The advantage of the proposed MPPT method is that characteristics of seaflow generator(SG) with respect to seaflow speed, requred in the conventional MPPT method, are not measurements of the rotational speed of the generator are required. Thus, there are advantages that seaflow generation system having features of lowing cost and complexity, and higher reliability can be designed. In this paper, Seaflow generation system using the buck-type dc/dc converter is proposed and the effectiveness of the MPPT algorithm is confirmed by matlab simulink.
