摘要
东风电网110kV输电线路长度均在2～12km以内，这种多电源超短线路群使得继电保护整定和配合关系恶化，常规继电保护装置无法满足电网对快速性、选择性、灵敏性和可靠性的要求．通过对东风电网继电保护的现状、存在的问题、未来电网发展的分析，提出了适合东风电网超短线路群的继电保护配置方案．
In view of that power transmission lines in the DFM Power Grid are usually long 2-12 kM, the condition of Relay-protection′setting and cooperating is increasingly difficult and complex. Through a thorough study of the current problems and tendency of the DFM power grid, the proposal of Relay-protection ′setting is put forward, which is compatible with ultra short lines group in the DFM Power Grid.
