数字化变电站互感器的选择

Selection of Mutual Inductor in Digital Substation

基于大理建设数字化变电站的实际需求,对电磁式互感器和电子式互感器的优点、缺点和应用场景进行了分析。本着实现数字化变电站可靠性、经济性和运维方便性的建设目标,提出了利用数字化仿真技术作为互感器的选择方法,并对仿真结果进行了校核,取得了良好的效果。

Based on the actual demand of Dali digital substation construction,the advantages,disadvantages and application scenarios of electromagnetic transformer and electronic transformer were analyzed.In order to implement the object of reliability,economy and convenience of operation and maintenance of digital substation,a method of transformer selection based on digital simulation technology was proposed.The simulation results were checked and good results were obtained.
