Transformer Solution for 220KV substation 

The long-range planning of the main transformer of 220kV substation is 4*240MVA, the capacity of the main transformer of present phase is 2*240MVA. Outdoor layout: double-bus configuration is adopted for the main electrical connection of future 220KV equipments,double-bus configuration is also used in present phase. The plan of 220kV outgoing line is 6 rounds,the present phase is 4 rounds. double-bus configuration is adopted for the main electrical connection of future 110kV equipments,double-bus configuration is also used in present phase. The plan of 110kV outgoing line is 14 rounds,the present phase is 8 rounds.
sectionalized single-bus configuration  is adopted for the main electrical connection of future 35KV equipments, sectionalized single-bus configuration is also used in present phase. The plan of 35kV outgoing line is 20 rounds,the present phase is 10 rounds of outgoing lines.

The length of the substation from east to west is 107meters,the width from south to north is 71.8meters. the door is towards north.the production complex building of 220kv substation is located at the south side of the substation, it is a two-floor building.the production complex building of 110kV substation is located at the north of the substation. The main transformer is at the south of the 110kV production complex building and it is arranged closely to the production complex building. The underground layer of the production complex building is cable layer.

This substation is non-attended substation,which adopts A3-5 scheme of "State Grid Company transmission and transformation project general design 110(66) ~750kV intelligent substation part"2011 vision.
