A comprehensive overview of substations

Along with the economic development and the modern industry developments of quick rising,the design of the power supply 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 and the of trend of the society life.

Electric power industry is one of the foundations of national industry and national economic development to industry,it is a coal,oil,natural gas,hydropower,nuclear power,wind power and other energy conversion into electrical energy of the secondary energy industry,it for the other departments of the national economy fast and stable development of the provision of adequate power,and its level of development is a reflection of the country's economic development an important indicator of the level.As the power in the industry and the importance of the national economy,electricity transmission and distribution of electric energy used in these areas is an indispensable component.。Therefore,power transmission and distribution is critical.Substation is to enable superior power plant power plants or power after adjustments to the lower load of books is an important part of power transmission.Operation of its functions,the capacity of a direct impact on the size of the lower load power,thereby affecting the industrial production and power consumption.Substation system if a link failure,the system will protect the part of action.May result in power outages and so on,to the
