Detection and Simulation of Power Quality for Grid-Connected Doubly Fed Wind Turbine

Abstract

Wind generation can affect the power quality of power supply system in a certain extent at the same time of energy conservation and emission reduction. In order to study the power quality problem of distribution network with wind power embedded, several indices of power quality are defined in this paper, and the doubly fed wind turbine model is established in detail. The voltage deviation, system frequency, and harmonic distortion rate are analyzed based on the simulation data outputted by PSCAD.
