Firstly , the 10kV power transformers were select edby the actual load calculate d. The reactive pensation was considered when select ed the 10kV power transformers .Ap artof iterative process was removed , so calculation is relatively simple. In the course of that, calculat ion of pensation capacity, power load , cable standard were s elect ed. 35kV power transformers was selected base on the total power load ,the reactive pensation was proceed. Secondly , high and low voltage circuit breakers , high voltage isolation switch, switch s and transformers were choosed through a nalyze s for system short-circuit calculation . Thirdly , l ayout, lighting, grounding and lightning protection for 35kV and 10kV substation were d evise d. Finally, the secondary circuit with estimate , measurement , protection and control were d evise d according to the system requirements .
