DESIGN OF 220kV TRANSFORMER SUBSTATION
ABSTACT:The produce of electric power is different from other industrial produce,whose process of product,transfer,change, distribute and consume is completed at the same time.The produce of electric power must keep balance,or it can’t function normally or even be destroyed.As the development of economy, the problem of being shot of electricity is becoming more and more serious.It’s a big problem how to optimize the disposition of electric resource and meet the electric power requirement.With the development of computer technology,communication technology and information technology,the comprehensive automation system technology develop faster and faster.The security and economic profits of the whole electric power network are greatly improved.The technology will be attached importance by electrical department and become key point of the transformr substation design.
This paper is design the 220KV transformer substation which include two parts of electrical devides.The first part mainly choose the capacity and specification of the transformer and all kinds of devides.It also calculate the burden,passive compensation and the shot-circuited current.Comprehensive automation system technology is the key point of the second part.It mainly include the development of electric power remote monitoring system technology. Then, systemically demonstrates the parts of the system. The working principles of system’s communication channels and the main function of the system are briefly introduced. Finally, this paper summarily introduces the peculiarities of Visual Basic instrument.
