Emulation of Direct-Drive Wind Energy Conversion Systems Based on Permanent Magnet Synchronous Generators

Abstract

This paper deals with realization of a direct-drive wind energy conversion system (WECS) emulator. It consists of modeling wind turbine blades, a permanent magnet synchronous generator (PMSG) and a rectifier which is linked to a boost converter. The wind turbine blades, PMSG and bridge diode rectifier models are implemented in a real-time platform which provides a variable DC voltage to a one-level hardware boost converter through a programmable DC power supply. The maximum power point tracking (MPPT) algorithm of the WECS is also developed and validated where the boost converter supplies a resistive load. The experimental results illustrate the efficacy of the proposed approach.
