关于电气化铁路负载对电网电能质量影响的研究

Study on the Influence of Electrified Railway Load on Power Quality of Power Grid

电气化铁路以牵引负载为主,这种负载基于大量电力电子器件工作,其运行会给供电网带来谐波超标、负序越限、低功率因数等问题,严重影响周边用户的用电权益。文章基于国家权威部门对京沪线电能质量测试结果,就电气化铁路负载对电网电能质量的副作用进行解析,同时从优化牵引技术、引入并联补偿技术等层面提出针对性解决方法,以期为推进铁路电气化而抛砖引玉。

Electrified railway traction load dominated the load based on a large number of power electronic device and its operation will bring overweight harmonic,negative sequence is more limited,low power factor to the power supply network,seriously affect the surrounding the user power interests.The authority of the state sector in Beijing Shanghai line electric energy quality test results based on,electrified railway load side effects on power quality analysis,optimize the traction technology,level,the introduction of parallel compensation technology and so on.The methods to solve them, in order to promote the railway electrification and initiate.
