摘　　要：大亚湾核电站仪控系统以模拟电子技术为基础,计划在30 a大修期间进行数字化改造,期间将对一层模拟系统进行全面数字化改造,二层人-机接口设备仍沿用主控室硬手操器控制。根据市场调研情况初步确定了四种基于数字化系统的手操器改造方案,最终考虑功能一致性、产品可靠性、技术可行性、开发成本、输入/输出(I/O)信号分配效率、应用反馈等多方面因素确定了开发新手操器并通过标准I/O板件接口的整体改造方案,该方案能够实现手操器与改造后数字化系统的最优接口,有效提升I/O板件通道利用效率,同时通过丰富的软件算法块功能和数字化系统故障诊断功能,增加了执行机构手自动无扰切换及过程信号质量位强制切手动等改进措施,有效提升了机组设备控制的可靠性和稳定性,也为同类数字化改造项目提供了重要参考方案。The instrument and control system of Daya Bay Nuclear Power Station is based on analog electronic technology,and it is planned to be digitized during the 30-year overhaul,during which the first-floor analog system will be completely digitized,but the man-machine interface equipment on the second floor will still be controlled by the hard hand operator in the main control room.According to the market research,four transformation schemes of hand operator based on digital system are preliminarily determined.Finally,the overall transformation scheme of developing new hand operator through standard I/O board interface is determined by considering many factors such as functional consistency,product reliability,technical feasibility,development cost,input/output(I/O)signal distribution efficiency and application feedback.This scheme can realize the optimal interface between the hand operator and the transfomed digital system,and effectively improve the utilization efficiency of I/O board channels.At the same time,through the rich software algorithm block function and digital system fault diagnosis function,the improvement measures such as automatic undisturbed switching of actuator and forced manual switching of process signal quality level are added,which effectively improves the reliability and stability of unit equipment control and provides an important reference scheme for similar digital transformation projects.
