基于FirmSys的三代压水堆核电站核安全级数字化保护系统设计概述

An Overview on the Firmsys based Design of Digital Protection System with Nuclear Safety Standard for the Third Generation of PWR Nuclear Power Station

伴随我国三代压水堆核电站自主化进程,在三代压水堆核电站中采用自主化的全数字化仪控技术已迫在眉睫,尤其是核安全级数字化保护系统更是实现全数字化仪控的关键环节。本文主要针对使用广利核公司自主研发的核安全级数字化仪控产品平台(FirmSys)为三代压水堆核电站提供保护系统解决方案的可行性进行初步探讨,为将来的工程设计和应用提供借鉴。本文首先说明了数字化安全级保护系统总体设计方案和系统功能的实现,然后进行了设计准则符合性分析,初步说明技术方案的可行性。

With self-reliant development in the 3G PWR （3rd Generation Pressurized Water Reactor） in China, the application of self-reliant full DCS （Digital Control System） technology in 3G PWR （3rd Generation Pressurized Water Reactor） becomes urgent, especially the application of safety-class digital protection system, which is a key system in DCS. The article made a preliminary research on the feasibility of providing protection system solution to 3G PWR with CTEC proprietary safety-class DCS platform （FirmSys）, providing reference to future engineering design and application. The article first briefly described the realization of digital protection system＇ s overall design and system function, and then analyzed design principle conformance which preliminarily proves the feasibility of the solution.
