At the same time, the economic development of in the countrys take precedence. The substation is through electrical equipment and distribution network in accordance with a certain way to work, so the substation is a very important component of the power system. Its work process to obtain electricity from the power system, and then through the transformation, distribution, transmission and protection functions, make electricity reliable and safe delivery to every electricity links. The reason why Substation to change the traditional control mode and design requirements is because the substation is the hinge of power control and transmission, only in this way the substation can adapt to inevitable trend which the modern industrial production, power system and social life development. The rationality of constructing substation is not only related to the infrastructure investment and improvement of substation itself, but also directly related to the safety and reliability of electricity consumption in daily life and the safety of enterprises and the safety of equipment.
