摘　　要：以上海市已运营的地铁一号线、二号线和轨道明珠线的供电变电站的电网谐波实测数据为基础,结合轨道交通的供电机理,分析了地铁负荷有功功率和无功功率的变化规律以及地铁的负荷频率特性,应用谐波计算软件对上海轨道交通2005年不同运行方式下的谐波电压电流进行了计算分析,评估了2005年上海轨道交通线路运营后对上海电网的谐波污染水平。An overall analysis is presented based on harmonics measurement data at the substations of Subway No. 1, No. 2 and Mingzhu Line （No.3）in Shanghai. Combined with the power supply mechanism of subway transportation, the variation principles of the active and reactive power are developed for the subway load. The load frequency characteristics are retrieved. In terms of various subway operation modes in 2005, further harmonics analysis is performed according to the fundamental data of harmorics pollution after subway being connected into Shanghai power grid. Harmonics pollution brought to Shanghai power grid is evaluated in 2005. The analyses show that the serious harmonic distortion will be brought to Shanghai power grid after the fundamental subway transportation network is formed.
