Maximum Power Point Tracking Control for Wind Power Generating System Using Permanent Magnet Synchronous Generator

Abstract

Recently, Permanent magnet synchronous generator (PMSG) is used for wind power generating system. PMSG has the optimal d-axis current which generates maximum power. However, the conventional methods cannot achieve maximum power point operation since d-axis current is generally kept at zero. In this paper, a maximum power point tracking control for wind power generating system with PMSG is proposed. The proposed method optimizes the d-axis current as well as the rotor speed of the PMSG on-line so as to generate maximum power. The effectiveness of the proposed method is verified through digital simulations.
