摘 要: 继电保护作为电力系统的安全卫士,在电力系统稳定运行中起着关键作用。本文就超高压保护整定中的失灵保护整定、互感对接地距离保护的影响、TV 断线保护延时以及光纤差动保护中 TA 断线闭锁等几个问题进行了探讨,并提出了解决的办法。 Relay protection to be as a safeguard for power system has appeared a key-action in steady operation of powersystem.Some problems,such as the setting of breaker failure protection,the influence of mutual inductance to grounding distanceprotection,TV disconnection-protection delay and TA disconnection-locking of fiber differential protection are discussed in thispaper,and the way how to solve the problems is also presented.
