Research on Digital Upgrade Verification Platform Scheme for Simulation Control System of Daya Bay Nuclear Power Station

According to the scope and actual situation of the existing simulation control system in Daya Bay Nuclear Power Station, the signal configuration, interface type and typical control loop are analyzed. In this paper, the technical requirements of the verification platform are put forward, and the verification platform based on DCS system, process simulation system and KRG system is set up. The specific verification contents are also given in detail. Using the verification platform to carry out the corresponding verification work, the differences before and after the improvement of the platform can be effectively identified to ensure the smooth implementation of digital upgrades.
