摘要
针对我国部分电气化铁路电力机车再生制动失效情况时有发生的现象,文章通过现场测试及分析,验证了外部电源电能质量是引起机车再生制动失效的重要因素之一。在此基础上,综合机车再生制动失效的相关因素,对供电系统可采取的改善措施进行了分析计算,并提出了相应的工程预防措施。
Abstract: Aiming at the phenomenon that regenerative braking failure occurs frequently in some electric locomotives of electrified railway in China, it validated that grid power quality is one of the important factors which cause the regenerative braking failure, through field measurement and analysis. On this basis, combing the related factors of locomotive regenerative braking failure, it analyzed and calculated the improvement measures which could be taken by power supply system, and proposed engineering solutions accordingly. Keywords: electric locomotive; external power supply; power quality; regenerative braking; failure analysis
