500kV变电所保护布置方案研究

Study on the laying of protection and control equipments in the 500 kV substation

以典型 5 0 0kV变电所为例 ,通过对分散布置于保护小间、分散布置于开关场柜、集中布置于主控楼等三个方案进行技术经济比较 ,得出了比较理想的结论 ,即下放布置于配电装置保护小间 。

A scheme for the laying of protection and control equipments in the 500 kV substation is presented, with technical and economical comparison,through three different schemes (laying in small special rooms in the electric field,laying in panels in the electric field and laying in panels in the control building).The measures to decrease electromagnetic interference after those protection and control equipments were locally mounted are put forward.
