Abstract
Electrical energy as a clean secondary energy provides living power and support the social production. Under the basis of the electric power industry developing in our country, power generation, substation, transmission and distribution of the whole electric power system has become a pillar industry of our country under the new era. The use of electricity is embodied in all aspects of People's Daily life. As plays the essential role in the grid of a large number of adoptions of 10 kV distributions, the masses of users generally care about how to improve the stability and reliability of distribution system is running. So to improve the stability and reliability for daily production and living has a special significance.
Some school public living area of 10 kV power distribution system design is my important research problem of this. As an important hub cohesion power grid with the school public living quarters each link of the design is particularly important. After understanding the basic situation, the use of access to user data load analysis and calculation to determine the reactive power compensation. Simultaneously short circuit calculation, the main electrical wiring design, selection and calibration substation equipments, relay protection setting, secondary loop scheme is determined. In the above link, the determination of the main wiring is a vital link, it is part of equipment selection, after distribution equipment installed such as the proposed has a decisive role, will also to the security and reliability of power system operation for a long time, flexibility, and the influence of the economy has to be reckoned with.
