针对大亚湾核电站失水事故(LOCA)监视系统(LSS)面临部件老化、备件无法采购导致系统工作不稳定及故障报警闪发的现状,提出对LSS系统进行整体升级的改造方案；描述了新LSS系统采用PLC产品及冗余配置后的设计方案,以及通过对LSS系统的计算模型及接口等关键技术进行研究与分析,并采取各种方法对功能进行验证,完全掌握LSS系统的计算模型,实现LSS系统的自主化设计和改造.%For LOCA Surveillance System (LSS) facing the aging parts, unable to purchase spare parts leading to unstable work and the flash failure alarm of LSS in Daya Bay Nuclear Power Station, the localized modification of the whole upgrading program is proposed. The design of new LSS system after using PLC products and redundant configuration is described. Based on researching and analyzing the key technologies of the calculation model and interface, and adopting various methods to verify the functions of LSS system, the calculation model of LSS system is fully grasped. The independent design and renovation is realized.
