摘　　要：本文分析了双馈型变速异步风力发电机的原理及数学模型,剖析了风电并网对电网调度、电压水平、电能质量的影响,指出风电机组的低电压穿越能力亦是影响风电并网的难点之一,并对比了目前几种低电压穿越技术方案。此外,本文还对风电的经济价值和节能减排效益进行分析,结果表明:随着风电规模的日益壮大,风电对火电置换的环境效益将日益显著。This paper analyzes the principle and and analyzes the impact on the grid scheduling, mathematical model of double-fed induction generator, voltage level, power quality that wind power is integrated into power grid, points out that the low-voltageride through capability of wind power is also one of the difficulties of wind power integrating into power grid, and compares with some ways of low voltage ride-through technology. This article studies the benefit of wind power＇s energy conservation and emission reduction, The result indicates that the economic value and environmental benefits of wind power integration will be increased along with the expansion of the using scale of wind power.
