چکیده

In this paper, a control system for the operation of a doubly fed induction generator (DFIG), feeding an unbalanced three-phase load is presented. The load unbalance is compensated using the front-end converter. The control system is based on positive and negative sequence components of current. MATLAB Simulation results obtained from a DFIG system and are presented and discussed in this paper. Keywords> DFIG, predictive current control, GSC-RSC, unbalanced load.

An Effective Rotor Current Controller for Unbalanced Stand-Alone DFIG Systems in the Rotor Reference Frame

This paper presents an effective rotor current controller for variable-speed stand-alone doubly fed induction generator (DFIG) systems feeding an unbalanced three-phase load. The proposed current controller is developed based on proportional plus two resonant regulators, which are tuned at the positive and negative slip frequencies and implemented in the rotor reference frame without decomposin...

Power Quality Improvement in a Speed Sensorless Stand-alone DFIG Feeding General Unbalanced Non-linear Loads

This paper reports the performance of a speed sensorless stand-alone Variable Speed Constant Frequency (VSCF) Doubly Fed Induction Generator (DFIG) capable of supplying all types of loads. The proposed method maintains the Total Harmonic Distortion (THD) of the machine current and the load voltage within acceptable limits. In contrast to previously proposed methods, in this paper, the stator si...

Analysis and compensation of voltage unbalance of a DFIG using predictive rotor current control

This paper analyzes the unbalance problem of a stand-alone doubly-fed induction generator (DFIG) under unbalanced loads and proposes a compensation method to balance the stator output voltage. The proposed compensation method is developed based on a predictive current control (PCC) method implemented in the rotor current controller. The development of the PCC is based on the discrete model of t...
