The design quality is good or bad, directly related to the power system security, stability, flexible and economic operation. This paper will design a region terminal substation, and design terminal protection. This manual to 110 KV substations as example, the article discusses the power system engineering of electric parts of the design of transformer substation the general process. This article through to the proposed generalization of the transformer substation and terminal equipment choice, and through to the load data analysis and safety, economy and reliability into consideration, determine the 110 kV, 10 kV and stand Lord of the electricity wiring, and
