摘　　要：智能变电站中合并单元设置与否应根据工程实际情况进行分析比较,以求整个设计方案更加合理、经济、资源利用最大化。针对智能变电站采用常规互感器的设计方案,对合并单元设置与不设置2种方式的优缺点进行了比较,并根据合并单元安装位置的不同,阐述了合并单元设置与否的影响因素。结合智能变电站工程建设实例,给出了2种方式下详细的技术、经济指标比较,提出了智能变电站合并单元是否设置的合理建议。It is necessary for analyzing and comparing the configuration scheme of with or without merging unit in smart substations based on practical engineering situation. Good energy efficiency and low engineering cost can be achieved because of a good configuration scheme. Due to the smart situation which applied conventional mutual inductors to sample,the advantage and shortage of the two schemes for merging unit are compared. According to the different locations of merging unit in smart substation, the influencing factors of with or without merging unit are illuminated. Finally, the detailed technical and economic index comparison of the two schemes are given based on a construction project of smart substation,and the reasonable suggestions on the choices of with or without merging unit are put forward.
