摘要
对水电站35 k V输电线路保护常规配置及特点进行了分析,指出了这些保护在短线路的应用上存在局限性,推荐线路光纤纵差保护作为替代方案,并通过实际案例阐述了方案的可行性和优越性,对其他水电站同类型短线路具有借鉴作用。
In the present paper,the regular configuration and characteristics of 35 kV electric transmission line protection are analyzed and the limitations are figured out.The optical-fiber line differential protection is recommended as the alternative solution.The reliability and advantages of the solution are stated by real example,which has reference value for other short lines of same type.
