摘要
高速动车组和大功率交直交电力机车运行中产生的谐波会造成牵引变电所低压用电设备频繁烧损,文章分析了27.5 kV自用电所含谐波成分,给出了增设并联型电能治理设备或能量路由净化装置的技术方案,对电气化铁路牵引变电所自用电电能质量改善有较大的理论意义和实际效果。
The harmonics generated in operation of high-speed EMUs and high-power AC-DC-AC electric locomotives will cause frequent burning of low-voltage electrical equipment in traction substation,the paper analyzes the harmonic contents of the 27.5 kV auxiliary power,presents the technical scheme relating adding of shunt electric energy treating equipment or purifying device for energy route,it has great theoretical significance and practical effort to improve the power quality of the auxiliary power of traction substation.
