摘要
为了减少黔桂电气化铁路牵引负荷产生的谐波和负序电流注入电网,降低谐波给供电系统及广大电力用户造成的谐波干扰和影响。分析水任变电站110 kV母线在系统不同运行方式下的谐波、负序、无功变化情况,得出了采用220 kV变电站的110 kV专线主供方式对黔桂电铁电力牵引站供电可降低电铁影响的结论。
In order to reduce the injection of harmonic and negative sequence current generated by traction load of Qiangui electric railway into power grid, and reduce the disturbance and influence of harmonic on power supply system and customers, the harmonic, the negative sequence and the reactive under different operation mode on 110 kV bus of Shuiren substation is analyzed. Conclusion is obtained which is that using 110 kV dedicated line from 220 kV substation as the main power supply mode of Qiangui electric railway traction load can reduce the influence of the railway.
