| 摘 要： | 电力系统非全相运行时对距离保护有较大影响。两相运行期间距离元件性能将恶化 ,应将其闭锁 ;但两相运行时健全相仍可能发生短路 ,此时保护应能准确切除健全相的区内故障。对两相运行工况及其复故障条件下距离保护的动作行为进行了仿真分析 ,探讨了基于故障分量距离继电器的解决方案 ,EMTP仿真结果证明了该方案的有效性

| Abstract: | The operating characteristics of distance elements would be deteriorated in 2 phase work condition and the relay therefore should be disabled; yet fault of the two sound phases within the protective zone should be removed correctly. A scheme based on fault component is given in this article after an analysis of the operating characteristics of distance relay during 2 phase running. The results of digital simulation using EMTP prove its validity. |
