关于CT断线功能在智能变电站中应用的探讨
|
摘要
国内主流厂家对于CT断线功能理解差异较大,保护相关标准中CT断线方面的性能指标要求较少,该文提出CT断线功能的一些重要性能指标;介绍国内主流厂家母线保护的CT断线功能,指出存在的不足;提出智能变电站CT断线特征的概念,对智能变电站母线保护的CT断线特征进行了分析;充分利用智能变电站信息共享的优势,设计新的母线保护CT断线功能实现方案,提升CT断线功能的性能指标,适应智能变电站的应用,给智能变电站保护相关标准的制定、运行维护、保护装置研制等提供参考。
There are large differences between major domestic manufacturers about understanding CT line-break function,and there are a few requirements about CT line-break performance index in protection standards.Some important performance indexes of CT linebreak functions are put forward in this paper;CT line-break functions about busbar protection IEDs of major domestic manufacturers are introduced,and the deficiencies are pointed out;The author puts forward a concept about CT line-break features in smart substation, and CT line-break features are analyzed about busbar protection in smart substation;the author makes full use of the advantages of information sharing in smart substation,and designs a new scheme of CT line-break functions about busbar protection to improve performance indexes of CT line-break function,to adapt to the application of smart substation,and provides the reference for protection standard setting,operation maintenance,and protection design etc.of smart substation.
