100kW급 고효율 부유식 조류발전시스템의 MPPT제어

초록

This paper presents the MPPT(Maximum Power Point Tracking)control method of the 100kW high efficiency seaflow generation. Because of seaflow's swirling, it is difficult to measure the velocity of a moving fluid. Therefore, except for previous method using information of the velocity of a moving fluid, the proposed algorism is controlled by tracking the optimal point, of the generator speed and maximum grid power. The vector control of the generator side converter and of the grid side inverter is controlled respectively to obtain maximum torque and to regulate unity power factor. Using Psim simulation, the validaty of control algorism is verified.
