摘　　要：基于甘肃酒泉地区大规模风电接入系统规划,通过测量统计的方法建立了风电场接入系统的谐波源模型,在电力系统不同运行方式下进行谐波潮流计算,并对比分析了现阶段和2015年千万千瓦风电接入系统电网谐波污染情况。计算结果表明,风电集中上网点谐波污染严重,谐波污染程度沿线路呈现衰减的趋势,离谐波污染源电气距离越远谐波幅值衰减越多,谐波次数也越来越少,且随着规划网架结构的不断增强,谐波污染源对电网的影响就越小。本文的研究将为电网规划设计和风电电能质量治理提供数据参考。The harmonic sources model of wind access to power system is established by measured and statistical methods.The harmonic power flow is analysed under different operation modes in power system based on the Gansu jiuquan area large scale wind system planning.The harmonic trend is analysed of the present stage and 2015 million kilowatt wind access to power system, calculation results show that the harmonics pollution is most serious at the point of wind access to the network, the harmonic pollution degree is damping along the line, the farther of electrical distance to harmonic sources the fewer harmonic, and the harmonic pollution decreased with the planning grid structure.This research will provide reference data for power grid planning and wind power quality management.
