FPGA技术在核电厂多样性驱动系统中的应用

FPGA Technology Application in Diversity Actuation System of Nuclear Power Plant

摘要: AP1000核电厂多样性驱动系统（DAS）为保护系统的后备。本文研究了DAS的功能和结构、可编程门阵列（FPGA）技术的基本结构以及FPGA在DAS自动驱动平台中的应用。结果表明，FPGA技术根据其结构和电路的自身特点，具备多样性能力强、复杂程度低、稳定性高、响应时间短和安全性高等优点，能满足核电厂保护功能的多样性驱动，并满足相关法规标准对DAS的基本功能要求。

Abstract: In AP1000 nuclear power plant (NPP), the diversity actuation system (DAS) provides a backup to the protection system. This paper focused on the function and structure of DAS, the filed programmable gate arrays (FPGA) technology and application of FPGA in DAS. The results show that the FPGA performs the characteristics of diversity, simple, high reliability, short response time and good security. And the FPGA can meet the requirement of diversity actuation function and relate rule.
