光纤差动保护与非全线速动事故范围扩大探讨

Discussion on the optical fiber differential protection and non whole -line accident expanded

依赖于通信技术的发展，差动保护得到长足的发展，该保护受系统运行方式影响小，动作快，能实现全线速动等优点，因此光差保护广泛应用于高压线路保护中。

Differential protection obtained the considerable development because that depended on the development of communication technology. This protection had few influence by system operation, and had some virtues like quick action and realization of the whole -line quick action etc, therefore optical fiber differential protection was widely used in high voltage line protection.
