Abstract
XF county 110KV substation is an important station in this distract, which is one of the
extremely necessary parts of the 110KV network in electric power system.
The design of the substation can be separated in two parts: primary part and secondary
part of the electric design.
The first part consists of specifications, computation book and Electrical engineering
drawings about the design. The specifications has several parts which are General
analysis of the station, Load analysis, The selection of the main transformer, Layout of
configuration, Computation of short circuit; Select of electric

devices, Power distribution devices, General design of substation plane and the design
of thunderbolt protection.
The second part also consists of specifications, computation book and electrical
drawings about the design
?/p>
Specifications and computation book include following
section: General, The evaluation and calculate of line protection, Transformer
protection, capacitor protection, Bus protection and Self-using transformer protection.
