Application of profibus-DP fieldbus technology in electric monitoring and control system

Electric monitoring and control system monitors the parameters of voltage,electric current and power and the regular work of protected device and checking system in order to satisfy the request for product and life.The technology of PLC and Profibus fieldbus and WinCC in Siemens are adopted in the paper to build electric monitoring and control system,according to the character of transformer substation. The electric monitoring and control are explained from the technology summary and the character of profibus fieldbus,the software and hardware deploy. The practice proves that the electric monitoring and control system is satisfied with the design request and the safe work of transformer substation.
