| 摘 要： | 随着电网建设的飞速发展以及电网光纤网络的不断完善,光纤电流差动保护在线路保护中的应用越来越广泛。光纤电流差动保护的关键是线路两侧装置之间的数据交换。要使两侧保护装置之间交换的数据准确,就必须保证两侧保护装置有精确的时间同步。文章从一则复用2M口光纤电流差动保护调试实例出发,分析了2M口时延产生的原因以及对保护装置测量数据的影响。

| Abstract: | Along with the development of power grid and improvement of optical-fiber network, optical-fiber current differential protection is used widely in line protection. The key of optical-fiber current differential protection is data exchange between devices on both sides of line. In order to ensure accuracy data, protection devices must be in time synchronization. With multiplex 2M optical-fiber current differential protection debugging as example, the paper analyzed reasons for time delay and its influence on device measurement. |
