为了保证电气化铁路高可靠性的供电要求和减少铁路牵引站接入对周边电网及其他用户的影响,在对供电方案进行研究时,需要分别从供电可靠性、电压等级、牵引变压器接线方式和谐波负序治理等方面进行技术分析与方案优化,以期达到两者兼顾的效果。结合近年来上海地区电气化铁路的建设,分析了将铁路牵引站接入电网时所需考虑的关键问题,并且讨论了在满足供电可靠性的前提下,如何来降低电气化铁路对周边电网的影响。
In order to ensure the high reliability of the electrified railway power supply requirements and reduce the impact of railway traction station access to the surrounding power grid and other users, in the study of the power supply scheme, we must separately from the power supply reliability, voltage level, traction transformer wiring harmony Wave negative sequence management and other aspects of technical analysis and program optimization, in order to achieve the effect of both. In connection with the construction of electrified railway in Shanghai in recent years, the key issues to consider when connecting the railway traction station to the power grid are analyzed, and how to reduce the impact of the electrified railway on the surrounding power grid is discussed under the premise of meeting the reliability of power supply.
