GPS技术在光纤差动保护调试中的应用

The Application of GPS Technology in Optical Fiber Differential Protection Commissioning

提出了一种基于GPS(全球卫星定位系统)光纤差动保护的试验方法,即在线路两端同时向各自的保护加入模拟区内或区外的各种类型故障量,使模拟线路故障真实情况成为可能。

Proposing a test method for optical fiber differential protection based on GPS （ global satellite posi- tioning systems）, thus every kind of fault guantity can be put into each protection at both and of the line, inside or outside the simulated zone simultaneously, and it is possible to simulate the real line fault coudition.
