Abstract
Along with the economic development and the modern industry developments of quick rising, the design of the power system become more and more completely and system. Because the quickly increase electricity of factories, it also increases seriously to the dependable index of the economic condition, power supply in quantity. Therefore they need the higher and more perfect request to the power supply. Whether Design reasonable, not only affect directly the base investment and circulate the expenses with have the metal depletion in colour metal, but also will reflect the dependable in power supply and the safe in many facts. In a word, it is close with the economic performance and the safety of the people.
The substation is an importance part of the electric power system, it is consisted of the electric appliances equipments and the Transmission and the Distribution. It obtains the electric power from the electric power system, through its function of transformation and assign, transport and safety. Then transport the power to every place with safe, dependable, and economical. As an important part of power’s transport and control, the transformer substation must change the mode of the traditional design and control, then can adapt to the modern electric power system, the development of modern industry of the society life.
This instruction booklet was a 220KV transformer substation electricity part preliminary design and main transformer's host protection designs and analyzes, elaborated in the electrical power system project a transformer substation partial electricity partial design entire process. Through to the transformer substation main wiring design, the short-circuit current computation, the electrical equipment moves, the heat-stable verification, the main electrical equipment model and the parameter determination, the 220kV power distribution equipment design, the main transformer protection disposition and so on, has completed in detail the electrical power system the transformer substation design.
