Analysis of Solution on KIC Power Distribution for Nuclear Power Plant

The power distribution for KIC has a decisive influence on the availability and reliability of KIC. The KIC power distributions were compared and analyzed based on the description of the structure and function of KIC system for two nuclear power plants. The situation of KIC with the single bus power loss was described. Some problems of both the projects were pointed out and some improvement suggestions were put forward, which would be the reference for subsequent improvement of plant overhaul, KIC power distributions of the other CPR1000 projects and three generation projects.
