摘要
对Ｔ接线路中纵联方向保护的各方向元件如何配合进行了探讨，结果表明，各方向元件的相互配合由于Ｔ接线路相对复杂的网络结构而更显困难，在某些情况下纵联方向保护可能不能满足系统对保护的要求，因此，应仔细研究它们在相互配合的过程中存在的死区及误动的区域，以便采取相应的补救措施弥补其不足。
In this paper ,the coordination of directional relays in pilot protection on teed lines is investigated. It’s results demonstrate that the property of directional relays on teed lines is different from that on normal lines and the coordination is more difficult for its relatively complex network structure. In some cases, the pilot protection may dissatisfy the demand of power system. Therefore, the conditions of rejective action or mistaken action in thecourse of coordination must be lucubrated in order to take the corresponding remedial measures.
