A New Approach for Controlling Direct-Driven PMSG Wind Turbines

K. Ragunathan, B. Geethalakshmi

Abstract


This paper presents control of wind energy conversion system (WECS) with permanent magnet synchronous generator (PMSG). With the modern power electronic technology, direct-driven PMSG have been increasingly used in wind turbine manufactures. In PMSG wind turbine with two back-to-back voltage source converter (VSC) are used like a commercial passive rectifier followed by an insulated gate bipolar transistor (IGBT) inverter. This paper investigates the new approach for controlling the direct-driven PMSG wind turbines; it has two side-by-side voltage source pulse width modulation (PWM) converters. The paper investigates new approach based on direct current vector control method and also investigates the conventional vector control. Thisnew approach has to control both the machine side converter (MSC) and grid side converter (GSC). The control strategy is developed for integrated control of PMSG for maximum power extraction, dc-link voltage control and grid voltage support control. The WECS have been developed using Matlab Simulink software to compare the conventional vector control method with proposed approach under steady state and gusty wind conditions.
