Design and Study of Electric Control System for Advanced Loader and Unloader of Pressurized Water Reactor
The loader and unloader is the key equipment for the material change of pressurized water reactor nuclear power plants.The electric control system determines the safety and reliability of the equipment operation,so it is necessary to design and study the electric control system for advanced loader and unloader.Through analyzing and comparing the design of the second-generation plus electronic control system for loader and unloader,the new anti-collision laser radar,online insulation monitoring,dual-side redundant encoder,redundant load secondary table,deflection optimization,automatic offset,maintenance mode,secondary confirmation and encoder selection,etc.,which significantly improves the comprehensive performance of the system.It focuses on the architectural design of electronic control system for advanced loader and unloader,programmable logic controller(PLC)system configuration,PLC program function transplantation and development,upper computer screen configuration and optimization and innovation,etc.,which can enable loader and unloader designers,commissioners and users to quickly understand the loader and unloader.This study has greatly improved the safety and reliability of loader and unloader operation and has positively promoted the research and development of fully automatic advanced loader and unloader.
