In order to improvepower transmission capacity of line

the series c apacitor of series compensation for long distance line shall be added to compensate inductive impedance.The purpose of this paper is to optimize the layout of the equipment platform in the series compensation station and get a good technical scheme with high economy.The layout of single-group series compensation platform is optimized with combination of Chengde 1 000 kV series compensation station project;several possible layout schemes for the whole station series compensation equipmentare proposed.Finally

it is concluded that

through technical and economic proposal comparison

thelayout plan of long strip and dual platform connected by tower can meet technical requirement

have best economicefficiency and be convenient in operation and maintenance.
