PSCAD_DFIG具体模型介绍
In this paper, a DFIG power conversion system is simulated and vector
controlled for improving power quality of the grid while injecting the required active
power of the system. 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 proposed 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.
