摘要
为保证城市轨道交通供电系统的安全可靠和经济合理,其牵引站的运行方式具有多样性,不同的运行方式对供电系统电能质量造成不同的影响。首先讨论了牵引站的不同运行方式,通过理论计算和仿真模型对城市轨道交通牵引站不同运行方式下谐波电流进行分析,并研究了某实际城市轨道交通牵引供电系统非特征次谐波产生的原因,研究结论对城市轨道交通供配电系统设计和运行管理提供一定的借鉴。
In order to ensure the highly safety, reliability and economy of the urban rail transit power supply system, the operation mode of urban rail transit traction station is diverse. Different operation modes of the power supply system have different effects on power quality. In this paper, the different operation modes of urban rail transit traction station were discussed, the harmonic current of the urban rail transit traction station based on the different operation modes was analyzed through theoretical calculations and simulation model, and the reason was studied which caused the non-characteristic harmonics of a real urban rail transit traction power supply system. The conclusion of the study provides a reference to design and operation management of the urban rail transit power supply system.
