Research on Power Quality Based on Doubly-Fed Induction Wind Generator

Abstract

The influence of grid-connected wind power generation system on power quality has always been a focus of researchers. Doubly-fed induction generators are the most widely used wind turbine generators in the wind power industry, and their impact on the power grid during power generation and grid connection has also received widespread attention. In this paper, based on the power quality problem of double-fed induction generators connected to the grid, three aspects of voltage fluctuation, flicker and harmonics are analyzed respectively, and the influence of this model on grid power quality is analyzed.
