摘　　要：讨论了引入负荷限制继电器,防止重负荷时测量阻抗进入距离继电器而引起误动;引入接地及相间距离继电器提高躲过渡电阻能力;以及采用低压距离继电器,防止继电器存在死区的合理而有致的输电线路距离保护继电器配置方案。This paper discusses reasonable and available distance protection relay configuration,including that importing load to confine relay so as to prevent measure impedance from distance relay during heavy load,then importing ground and in-phase distance relay to improve dodging transition resistance ability,at last also,low voltage distance relay to prevent dead area existing in relay.

关 键 词：继电器 距离保护 过渡电阻
