The Design And Improvement Study Of Ansteel Slag Company’s Supply And Distribution System

Electricity is the major energy and power in modern industrial production and people’s lives, while supply system plays a significant role for a factory power. In recent years, along with the fast development of economic construction, many large corporations need highness security of the Power distribution system, especially the steel corporation, and the metallurgy corporation, and the petrifaction corporation. So the supply and distribution system and competitive automatization system in corporation has been researched in 2000’s.The study object of the paper is about the supply and distribution system and competitive automatization system of Ansteel Slag Company. The power distribution system in steel corporation belong to high-tension power distribution system, and it have much difference form power distribution system in electric power system, such as:electric load is highly convergence in it; it have a large number of equipment with high voltage and high power; electric load in it need highly safety; There have much issue between with the power quality and the electromagnetism compatibility; it have much relation with other system;First, according to analyzing the concrete situation about the possessed load and the increased capacity, it is to choose the location of the new switch room, definitude the load grade, adjust the load together with generatrix, confirm the system running plan and the parameters of electrical power distribution cabinet. Choosing and testing the electrical devices matched condition, researching and designing the second loop by calculation of load, short circuit current and peak/short-time withstand current test. They can guarantee the effective running for the loop of the controlling, adjusting, relay protection and automation equipment, measurement and signal and the operated supply power.Second, on the course of system optimizing, to save energy, fund and the improving cost, it should raise the utilization and the usage efficiency of electric power as far as possible.Third, it studied the system structure of the automation system and combined ourselves to discuss the foundation of intelligent transformation and distribution station as the basis of realization for the system improvement. On the base of designing the power supply and distribution system with the state of realizing automatization for power supply and distribution room, we progress feasibility analysis from design principle, system configure and construction, function and technique index.At last, the soft design is also progressed. And to upgrade the power supply and distribution room’s intelligence level with the design of the automatization system. And the design of intelligent systems actually runs well in the scene.
