介绍了基于现场总线控制器冗余原理的FCS165现场总线控制系统中控制器FCP01的硬件电路结构。分别从主备判断、实时数据备份和交换主控权等方面设计了控制器冗余功能。在华能秦岭电厂660 MW机组上的应用结果表明

FCP01控制器主备切换时间可达200μs

满足600MW及以上等级机组控制要求。

The hardware circuit structure of controller FCP01in FCS165field bus control system was presented

on the basis of the redundancy principle of field bus controller.From such aspects as main role judgement

real-time data backup and exchange control

the redundancy function of controller was designed.Its application on the 600 MW unit in Huaneng Qinling Power Plant showed that

the work and backup state switching time of FCP01controller can reach up to 200μs

which satisfied the control requirement for unit over 600MW.
