摘要
通过对南广铁路郁南牵引站接入系统一次接线方案进行分析,比较单相接线和V/X接线对电气化铁路牵引负荷的影响,提出牵引站220 kV供电线路的继电保护配置原则,认为全线速动保护宜采用工频量差动保护来实现线路主保护。在对RCS-904微机距离保护与RCS-931微机光纤电流差动保护进行分析的基础上,阐述了南广铁路郁南牵引站供电线路继电保护设计的具体情况。
By analyzing primary connection scheme for access system of Yu＇nan traction substation of Nan-Guang railway and comparing impacts of single-phase connection and V/X connection on electrization railway traction load,the paper brings forward configuration principle of protective relaying on 220 kV power supply lines of traction substation,and it believes that differential protection of main frequency parameter should be adopted for quick-trip protection to achieve primary protection of lines.On the basis of analyzing distance protection of RCS-904 and fiber current differential protection of RCS-931,the paper also elaborates on details of protective relaying design of power supply lines of traction substation of Nan-Guang railway.
