This paper discuss the configuration, operation and power flow control strategies of a doubly fed induction generator (DFIG) with back-to-back PWM converter for variable speed wind turbines. The mathematical model of the DFIG is taken as appropriate d-q reference frame and their performances are in terms of stator currents references tracking. In order to control the power flow of the network, ...

Abstract To suppress the subsynchronous oscillation in doubly-fed induction generator (DFIG) system with Static VAR Generator (SVG), a feedback linearization control (FLC) method for rotor-side converter (RSC) is proposed, and its effect under small disturbances analyzed verified. Firstly, 22-order time-domain model of DFIG SVG established. Secondly, combined principle linearization, correspond...

This paper proposes a design of a speed control of three phase induction motor fed from wind turbine using genetic algorithm. The wind turbine acts as a prime-mover for doubly fed induction generator. To make the system stable, proper monitoring is required or sometimes an auxiliary system can also be a good option, which can support the primary system during undesirable conditions. The three p...
