基于LCC的电子式互感器选型经济性分析

An Economic Analysis of Type Selection of Electronic Transformers Based on LCC

针对电子式互感器在某新建110 kV智能变电站中如何选型的问题,分析了各种电子式互感器的应用现状和优势,并基于全寿命周期原理对互感器选型的3种方案进行了详细的技术经济性分析与对比,确定选择方案2有源电子式互感器为最佳配置方案。

In view of the type selection of the electronic transformers applied to a newly-built 110 k V digital substation,an overall analysis has been made of the current application and advantages of various types of electronic transformers.Based on LCC, a detailed efficiency analysis of and a comparison between the three different proposed selections of electronic transformers shows that the active electronic transformer proves to be the best configuration scheme among all the three options.
