摘要
针对在役核电站仪控系统数字化改造这一问题,首先分析了改造所要实现的目标,然后阐述了目前DCS和FCS两种改造方案,接着从备件、老化、系统性能、系统功能、系统安全可靠性、运行管理、经济性、改造实施、成熟供货商等多个方面进行分析和比较,最后认为后者有着诸多显著的优越性,应该尽快发展核电站FCS仪控系统。
In the light of digital modification of instrument and control system of NPPs in service, the object to be implemented is analyzed firstly. Then, two strategies of modification currently existing, i.e. DCS and FCS, are expounded. These strategies are analyzed and compared between various aspects, e.g. spare parts, aging, system performance, functions, security, reliability, maintenance, management, economy, implementation, and suppliers, etc. Finally, FCS scheme is proven its remarkable advantages for I＆C system of NPP, such system should be developed as soon as possible.
