Abstract
In this paper, the improvement measures of important load power supply mode of Qinshan Phase 2 Extension Project are summarized, involving important loads of power supply to the control cabinets of the reactor protection regime (RPR), the process instrument control system (KRG) and the digital electric hydraulic (DEH) control system. The improvement is performed by automatic or manual switching for dual power supply and adding diesel generator backup start logic. Through the research on these improvement measures, the impact of these improvement measures on operation was analyzed. In addition, the problems after implementation of the improvement measures were analyzed and discussed, and suggestions for subsequent improvements were proposed.
