| 摘 要： | 智能变电站线路光纤差动保护当一侧采用全光纤电流互感器，另一侧采用传统电磁式电流互感器时．为保证光差保护投运后的安全可靠性，须对线路两侧的光纤差动保护装置同步性能进行测试．文中给出了一种集成测试环境下基于一次升流的线路差动保护同步性能的测试方法，基于此对不同厂家的线路差动保护进行同步性能测试．试验数据对比分析进一步表明了线路差动保护同步性能测试的重要性，保证了智能变电站投产的安全性。

| Abstract: | Line optical differential protection of smart substation using optical electric current transformer in one side and traditional electromagnetic TA in the other side.It is necessary to test the synchronization of asymmetric differential protections in order to ensure safety and reliability of the system after optical differential protection put into operation.An experimental method was proposed to test synchronization of the line differential protections based on rise flow under integration test environment.The synchronization test of different differential protections system was carried out by using this method.Comparative analysis of the results indicates that it is important and necessary to test the synchronization for digital line current differential protection. |
