doi:10.11985/2015.11.002

Abstract

Abstract:

In order to improve the maximum power point tracking performance of the small-scale permanent magnet synchronous wind power system(WPS), combing with the small-scale wind generator operating characteristics, a segmented variable step hill-climbing method suitable for the small-scale WPS is proposed based on the two classic hill-climbing method, which can fast stabilize the system at the maximum power point. Based on it, the simulation system is built by using Matlab/Simulink. And then the direct-driven WPS experimental platform is constructed with the TMS 320F28335 DSP core. The effectiveness and superiority of the proposed hill-climbing method is verified by simulation and experiment.

Key words: Direct-driven wind power generation system, maximum power tracing, variable step climbing method, segmented variable step, permanent magnet synchronous generator
