time distance relay

基本解释

But we have a problem, Jack. The distance between here and New York is causing a twenty-two-second real-time delay in the satellite relay.
沉默了一阵的雅梅终于开口，“但我们有个问题，杰克，这里和纽约的距离会造成22秒的卫星传输实时延迟。”
The distance protection with inverse time characteristic is the best choice to solve the conflict between fast trip near the protecting relay and reliable trip at the end of protection zone.
反时限距离保护是解决近范围快速动作与保护范围末端可靠动作之间矛盾的最好策略。
At present, the inverse-time characteristic of zone I distance relay has some defects such as conservative protection domain and long time delay when the fault is at the end of the protected line.
针对目前快速距离保护采用的保护范围反时限特性具有保护范围的开放很保守、不能保证远端故障的快速切除等缺陷，提出了基于波形系数的自适应距离保护方案。
