Network fault diagnosis and rectification Suggestions for 300MW unit under I/A Series system

摘要

With the progress of science and technology, DCS has been widely used in the field of power plant automation. It integrates modern computer technology, modern control technology, modern communication technology and CRT technology to realize the monitoring and control of power production process. DCS network adopts 10Mbps Ethernet, which is the data transmission channel of DCS system. Its stability is related to the safe operation of the whole power plant. Therefore, more and more power generation enterprises begin to attach importance to network security management of DCS. In this paper, the author puts forward his own views on the network failure phenomenon of Foxboro I/A Series system, and gives the solution, hoping to have some reference significance for the safety management work of other similar DCS network of the unit.
