摘　　要：为实现电厂中现场总线设备应用的规范化,分析了现场总线设备的实际应用情况,提出现场总线设备在控制系统组态中的标准化方案以及诊断点选取原则。以EMG电动执行结构为例,介绍了电厂现场总线设备使用时模块的选取原则、诊断点的引入格式、命名规范等,并以瑞基电动执行机构为例对现场总线设备的常规组态和采用标准化方案后的组态进行对比分析。结果表明,采用标准化组态方案可实现对现场总线设备运行状态的实时监控,降低设备的维护成本,提高设备的可靠性。In order to standardize the application of fieldbus device in power plants,the design specification of diagnosis points of fieldbus device was proposed after analyzing the actual application situation of field- bus devices in power plants. The configuration normalization of the fieldbus device in control system was also introduced in detail. Taking the EMG electric actuator for example, the selection principle of the mod- ule,the introducing format of the diagnosis points and the naming rule of each point were introduced. Moreover, the normal configuration of the fieldbus device and the standardized one was compared by taking the RAGA electric actuator as an example. The results show that, using the new configuration scheme can realize real time device status monitoring, reduce the maintenance cost and improve the reliability of the fieldbus device.
