电气化铁路接入对电能质量评估影响的治理研究

Research on the Governance of the Impact of Electrified Railway Aaccess on Power Quality Aassessment

供电和铁路等部门高度重视、重点关注电气化铁路各种突出性问题,电气化铁路电能质量综合性补偿成为电气化铁路配套建设技术研究的核心。鉴于此,从影响电气化铁路接入出发,分析电能质量,以三相电源系统接入原理为基础,针对性地提出了降低电气化铁路负序电流对供电系统影响、电气化铁路谐波具体治理措施、电能质量补偿方法。

Power supply and railway departments attach great importance to the various outstanding problems of electrified railway at present.Comprehensive power quality compensation for electrified railway has become the core of research on electrified railway supporting construction technology.In view of this,this paper will start from the impact on the access of electrified railway,analyze the power quality,put forward the access principle basis of three-phase power supply system,and put forward targeted measures to reduce the impact of negative sequence current of electrified railway on the power supply system,specific treatment measures for harmonics of electrified railway,and how to compensate electrified railway for power quality.
