摘要
基于《牵引供电系统继电保护配置及整定计算技术导则》,结合既有电气化铁路开闭所、牵引变电所等设备运行方式、综合自动化保护装置特点、牵引负荷实际需求,提出了完善开闭所进线、牵引变电所馈线及牵引变压器继电保护配置及整定计算的思路和方法,通过实际案例验证了所述观点的正确性和必要性,并提出了典型的应急供电情形下保障运输秩序的继电保护整定方案。
In accordance with the Technical Guidelines for Relay Protection Configuration and Setting Calculation of Traction Power Supply Systems,and with reference of operation modes of sectioning post and traction substation of existing electrified railway,characteristics of protection devices for integrated automation system,actual requirements of traction loads,the thoughts and methods for protection configuration and setting calculation for incoming lines of sectioning post,feeders of traction substation and traction transformer relays are put forward.The correctness and necessity of the thoughts stated are verified through actual cases.And a relay protection setting scheme for ensuring order of transportation in typical emergency power supply situations is proposed.
