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.
