摘要
针对目前国际上电气化铁道主要采用的供电方式,相应的负荷不平衡的特点,以及传统的通过提高电气化铁道变电所接入系统的短路容量来减小负序电流等做法的局限性进行了讨论。较为详细地介绍了SVC和STATCOM在电气化铁道中的具体应用,并进行了比较,指出适合中国当前国情的应用方式。
Discussions are carried out on the widely used power supply systems in international electrified railways ,which featureload un-equilibrium , and the conventional limitation to decrease the negative phase sequence current by increase the short circuit capacityof incoming system of railway substations.Practical applications of SVC and STATCOM to electrified railways are set forth and compared.The way fit in current domestic applications is suggested.
