Design is reasonable, not only directly affect the infrastructure investment, operating costs and the consumption of non-ferrous metals, will also be reflected in the power supply reliability and security of production, it and the economic efficiency of enterprises is closely related to personal safety equipment. Electricity substation is an important component of the system, from electrical equipment and distribution network at a certain wiring posed, he obtained power from the power system, and then power is safe, reliable And economical delivery of electrical equipment to switch to each place setting. As the hub of power transmission and control, substation design and must change the traditional control mode, to adapt to the modern power system, modernization of industrial production and social life trends. With computer technology, modern communication and network technology, for the
