Modeling and simulation of variable speed constant frequency wind power generation system with doubly fed brushless machine

The variable speed constant frequency (VSCF) wind power generating system with doubly fed brushless generator (DFBG) has the advantage of high reliability and high efficiency. This paper introduces the structure of DFBG and the composition of VSCF wind power generating system with DFBG. The coupling inductance parameters of DFBG are also given and analyzed. Based on MATLAB/SIMULINK technology, the simulation model of DFBG was built, and the control performances of VSCF wind power generation system with DFBG are simulated. The results show that the DFBG can realize VSCF operation and the DFBG simulation module built in this paper can be used for simulation study on the DFBG and associated control systems.

I. Introduction

In recent years, wind power generation develops with 30% growth rate every year in the world, and becomes one of the new energy source with the fastest developing speed.
