The Characteristic Of Steel Factory Power Supply & Design And Implement Of Synthesis Automatic System

Along with the expansion of electric power system and the improvement of modernization, primary industry country in the world research on the compositive automatization of transformer substation, after 1970's. Now it have come into the moment of application after the development of twenty years. In 1980's the domestic research carried on and developed fast. 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 compositive automatization system in corporation have been researched In 2000's just now. It posterior to the compositive automatization system in power system.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:1. Electric load is highly convergence in it;2. it have a large number of equipment with high voltage and high power;3. Electric load in it need highly safety;4. There have much issue between with the power quality and the electromagnetism compatibility;5. It have much relation with other system;It is necessary to design the compositive automatization system for the power distribution system in steel corporation. It can watch, measure, protect, control and communication. It can accord with the power distribution system in steel corporation, and afford the safe an saving work.With the characteristic of the power distribution system in steel...
