Simulation of Variable-Speed Wind Power Generation System using Capacitor-less AC-AC Converter and Switched Reluctance Generator

Abstract

This paper proposes a capacitor-less AC-AC converter for a variable-speed wind power generation system (VSWPGS) using a switched reluctance generator (SRG). As a new type of converter, the capacitor-less AC-AC converter was developed based on the matrix converter and applied to a VSWPGS to control the power between the SRG and an electric system. The VSWPGS using the capacitor-less AC-AC converter and SRG was modeled with Matlab/Simulink. The model considered a mechanical model including a wind turbine, the SRG, the capacitor-less AC-AC converter, and a controller. The simulation results for wind velocity changes verified the performance of the proposed VSWPGS using the capacitor-less AC-AC converter and SRG.
