下坂地水电站220kV线路保护的设计及特点

摘要

根据下坂地电站主接线的形式,提出了220 kv线路保护的设计原则,在此基础上详述了下坂地220 kV线路保护的配置,并分析了其保护配置主要特点.该保护装置能迅速并有选择性的切除故障,有效地保证下坂地水电站和电力系统的安全运行.%According to die pattrn of the main wire connection in Xiabandi hydropower station. this paper proposes the design guidelines for the 220 kV transmissiom lines, based on which the paper discusses in detail the configuration of the protection. and explores the main features of the configuration.This protection equipment can cut off faults rapidly and selectively, thus guaranteeing the safety operation of the station and the electric power system involved.
