Abstract
Power is the major energy and power of the modern industrial production, an important material basis for achieving production automation. Along with the development of industrial electrical automation technology, plant of rapid growth of electricity consumption, the quality of the power, supply- reliability, as well as the technical and economic indicators are required for increasing. Power not only transform form other forms of energy easily, but also easily be converted to other forms of energy to supply; The transmission and distribution of electricity is very simple and economic, also easy to control, adjust and measure, it is favorable to realize automatic production process. Therefore, power is widely used in modern industrial productivity, the entire national economy life as well as the national economy construction.
This project used the basic principle of the power-supply design and its method to design the primary circuitry system in the 10kV substation of the factory, understood the development situation of substation technology and the technology development trend in our country on the basis of existing professional knowledge, according to the modern electrical system design requirements, design a 10kV integrated automation substation.
Key word: 10kV substation, primary circuitry system, the computational load
