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。 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. Computation book, Electrical engineering drawings and catalogue of drawings are attached in the end。 There are nine drawings total, in which four are prepared by hand, others are prepared by computer in which installed the software electrical AutoCAD. From other view, it also can be classified as first part and second part. This is a design of substation for graduation design test. It can strengthen our specified knowledge.
