The Synthetical Automation Of Transformer Station Based On CAN Field Bus

The paper design the synthesized automation system of transformer substation based on CAN busfield combining the subject of the Zhunneng Electric Company ,adopting the advanced technology of busfield.The intellectual code is the minimum unit of the system ,so we carry on the hardware and software design of the code,which gathers the anolog quantity of the voltage and current and gathers the discrete magnitude of the isolated switch and the circuit breaker and transforms the signals between RS232C and CAN and controls the switches etc.And we design the interfaces of system using the configuration software —— Kingview 6.5 on Industrial Processing Computer in last machine and dispatcher's center ,realizing the telecommunications between the four substation and the dispatcher's center through telephone line .The design realizes the automation of the power station adopting the busfield technology.
