摘　　要：南龙铁路投运后,渔珠牵引变电所功率因数长期偏低。经分析,原因在于线路开通初期,客运行车密度低,而渔珠牵引变电所27.5kV馈线电缆长度较长,空载时容性无功较大,造成功率因数偏低。针对该种情况,本文研究探讨了3种提高功率因数的措施。After the Nanlong Railway was put into operation,the power factor of Yuzhu Traction Substation has been low for a long time.After analysis,the reason is that in the initial stage of the line opening,the passenger vehicle density was low,and the 27.5kV feeder cable of Yuzhu Traction Substation was long,and the capacitive reactive power was large at no load,resulting in a low power factor.In view of this situation,this paper studies and discusses three measures to improve the power factor.
