摘要
光纤电流差动保护是高压和超高压线路主保护的发展趋势。根据光纤分相电流差动保护的基本原理,详细阐述了光纤电流差动保护联调方案,其中包括检查两侧电流及差流、模拟线路空充时故障或空载时发生故障、模拟弱馈功能以及模拟远方跳闸功能。同时分析了光纤电流差动保护定检中存在的危险点,并提出了相应对策。
Fiber optical current differential protection is the main protection＇s development trend of high and ultra high voltage transmission lines.According to the theory of fiber optical current differential protection,this paper illustrates the scheme of joint commission for line fiber optical differential protection,including checking double-ended current and differential current,simulating faults in charging or non-load, and simulating radial lines＇operating condition and remote tripping.And aiming at danger in regular check,the solution is given.
