燕化110kV系统继电保护配置方案

THE CONFIGURATION OF RELAY PROTECTION FOR 110KV SYSTEM

分析了燕化１１０ｋ Ｖ 系统继电保护的现状和存在的问题，介绍了微机光纤纵差保护装置和 Ｏ Ｐ Ｇ Ｗ 在燕东线（ 即联络线） 的应用，论证了南瑞 Ｌ Ｆ Ｐ—９４３ Ａ 型微机光纤纵差保护装置及架空地线复合光缆 Ｏ Ｐ Ｇ Ｗ 在燕化１１０ｋ Ｖ 短线路上应用的可能性，结合燕化１１０ｋ Ｖ 系统的特点，提出了燕化１１０ｋ Ｖ 系统继电保护的设置方案和建议。

An introduction of the existing circumstances and problems in relayprotection for 110kV system in BYPC,and the applications of microprocessor based optical fiber differentical protection divece and OPGW used on Yandong transmission line are given.The probability that Naris model LFP-943A microprocessor based optical fiber differentical protection and OPGW can be used on the short transmission lines for 110kV system in Yanhua are proved.Suggestions and configuration of the relay protection for the 110kV system are proposed.
