基于CAN总线的变电站综合自动化系统的设计

以CAN总线为通信手段,构成基于现场总线的变电站综合自动化系统;通过对变电站自动化现状的分析,介绍了基于CAN总线的变电站综合自动化系统的底层硬件设计,包括模拟量输入输出智能节点的设计、离散量输入输出智能节点的设计、通信协议转换单元的设计等;并采用组态软件--组态王6.01进行监控界面的设计,实现了与下位机的数据通信及与上位机之间的通信;采用先进的CAN总线技术,降低了成本,实现变电站的无人值班,远方调度通过网管软件能够及时地监控各变电站的电压、电流、功率的变化,断路器、隔离开关的状态,及时地发现和处理故障,实现了变电站的综合自动化.

Automation of the Transformer Substation Based on CAN Fieldbus

This thesis takes CAN fieldbus as communication means forming the synthesical automation system of the transformer station. By way of the situation analysis of the transformer station , we design the basis hardware on the first floor, including the intelligent node design of analog input/output , discrete input/outpl and communication protocol cell. Using configuration software - Kinview 6.01 to realize the communication between the lower machine and the superordinate machine. The introduction of the advanced CAN busfield technology lowers the cost, realizes the unmanned transformer substation , control center can supervise the variety of lhe voltage, current, power synchronously, the state of the breaker and the insulated switch , realizing the automation of the transformer substation.
