【摘要】 在已建机组上实施火力发电厂厂级监控信息系统(SIS)的技术关键和难点在于原有机组控制系统与SIS的接口。以华能福州电厂4×350 MW机组SIS为例,介绍了采用美国OSI软件公司研制的PI数据库接口与机组控制系统通讯的OPC、TCP/IP及UDP 3种典型协议及其配置方法和注意事项,为类似机组中实施SIS提供参考。更多还原

【Abstract】 The key and difficult point on implementing plant-level supervisory informention system(SIS) in thermal power plant on units already constructed lies on interface between the original control system of unit and the SIS.Taking the SIS of 4×350 MW units in Huaneng Fuzhou power plant as an example,the three kinds of protocol,namely OPC,TCP/IP,and UDP,which adop PI database interface developed by OSI software company in USA for communication with control system of the units,as well as their allocation method and other matters needing to pay attention have been presented,providing reference for implementing SIS on other similar units.更多还原
