核电厂安全级控制显示装置的软件设计

Software Design of the Nuclear Power Plant S-VDU

安全级控制显示装置是核电厂操作员与数字化核安全级控制保护系统进行交互的人机接口,因其功能强大,且具备高度可靠性等特点,一直以来我国核电厂都需要进口安全级控制显示装置。GPU200是广利核公司自主研发的核电厂安全级控制显示装置,本文从确定性、可靠性、可维护性和人因工程等维度阐述了GPU200的软件设计,尤其是自监督等关键技术的实现方法。目前GPU200作为我国首套核安全级设备已成功应用于阳江核电厂5、6号反应堆控制保护系统。

S-VDU is the HMI that between nuclear power plant operator and digital nuclear safety protection system. Because of its powerful function and high reliability, nuclear power plants in China always need to import S-VDU in the past. GPU200 is a nuclear power plant S-VDU which developed by CTEC with independent intellectual property rights. This paper describes the software design of GPU200 from the dimensions of certainty, reliability, maintainability,human factors, especially, the key technology implement method about self-supervised and so on. At present, as China＇s first nuclear safety equipment, GPU200 has been successfully applied to the Yangjiang nuclear power plant No. 5 and No. 6 reactor control and protection system.
