Abstract :
The dynamic performance of a vector controlled DFIG power conversion system is studied and the power quality improvement of the grid is investigated. The system model proposed in this paper is developed in the dedicated power electronics and system simulation tool, PSCAD/EMTDC. The model also includes dynamic wind speed fluctuations and control of a soft starter, enabling simulation of the power quality characteristics of the wind turbine. Based on the simulation results, it is proved that the DFIG is capable of simultaneous capturing maximum power of wind energy with fluctuating wind speed and improving power quality, that are achieved by cancelling the most significant and troublesome harmonics of the utility grid. Dynamic power factor correction and reactive power control are the other two significant features of this technology
