火电厂现场总线控制存在问题及对策

PROBLEMS EXISTING IN FIELD BUS CONTROL OF THERMAL POWER PLANTS AND COUNTERMEASURES THEREOF

介绍了现场总线技术在火电厂的应用现状,对总线类型的选择、总线电缆设计、总线设备接口、总线设备故障替换等进行了探讨。对现场总线因缺乏与之相对应的设计规范、安装要求、智能设备的数据传输要求、通讯接口要求等在应用和设计中出现的问题提出了解决方案。

The status quo of field bus application in thermal power plants has been presented,and an approach to the type selection of field bus,the design of bus cables,the interface of bus devices,and the replacement of faulty devices etc.being made.The solutions to problems encountered in engineering design practices,such as the lack of design speccifications and installation requirements,as well as data transmission requirements for intelligent instruments and for communication interfaces etc.,have been put forward.
