核电厂仪控系统总体架构设计要求研究

Study on the Requirements of Overall Structure of NPP I&C System

在核电厂仪控系统设计过程中,需明确仪控系统架构的设计要求。通过对仪控系统架构要求的研究,确定仪控系统总体架构设计要求。从纵深防御、独立性、多样性、仪控系统功能分类和设备分级、网络安全和灾害防护等方面提出了总体架构的设计原则,并提出了仪控架构的设计步骤。

During the design process of nuclear power plant I&C system, it is necessary to specify the design requirements of I&C system architecture. Through the research on the architectural requirements of I&C system, the overall architectural design requirements of I&C system are determined. The design principles of the overall architecture are put forward from the aspects of defense in depth, independence, diversity, function classification and equipment classification of I&C system, network security and disaster protection. The design steps of I&C architecture are presented.
