针对电抗器的匝间短路提出了一种自适应补偿的短路保护方法,由系统零序回路零序源的所在位置来决定故障产生的位置,以提高匝间短路保护动作的灵敏度,同时克服了传统保护在系统无穷大时电抗器内部故障的死区问题,而在外部任何非正常运行工况下不会误动。
針對電抗器的匝間短路提齣瞭一種自適應補償的短路保護方法,由繫統零序迴路零序源的所在位置來決定故障產生的位置,以提高匝間短路保護動作的靈敏度,同時剋服瞭傳統保護在繫統無窮大時電抗器內部故障的死區問題,而在外部任何非正常運行工況下不會誤動。

This paper proposed an adaptive compensation method of short circuit protection in view of the reactor interturn short circuit, by locating the system zero sequence circuit zero sequence source place to determine the place of the malfunction, thus to improve the sensitivity of short circuit protection, at the same time overcoming the reactor failure problem of dead zone in traditional protection when the system is inifnite and not maloperation in external any abnormal operating condition.
