Research of the communication between the third-party system and digital control system of nuclear power plant

Abstract： As the DCS is widely used in nuclear power plants, the main control room of nuclear power plants is also transitioning to an advanced main control room with better functions and more centralized layout. This technical feature makes the main control room operator mainly rely on the CRT and keyboard and mouse on the operator station to realize the monitoring of the plant process system, so it is necessary to integrate the third-party system with the DCS system for information and monitoring. Based on this requirement, this paper introduces the general principles of interface design, specifies the interface design between DCS system and third-party system of Fuqing Nuclear Power Plant, and discusses the implementation of using FDSI module of I/A platform to realize the interface between third-party system, taking the interface between DCS and KRT system as an example.
