摘要
针对基于CPU技术的数字化核电仪控系统存在共因故障的缺陷。将FPGA技术引入到核电站多样性系统中,使其成为保护系统的后备系统。考虑到FPGA技术和CPU技术在运行机制上有很大的区别,进一步提出FPGA技术应用于多样性系统的关键问题和解决方法。分析结果验证了该应用的正确性和可行性,表明了FPGA技术必将成为核电站DCS行业发展方向。
Against to the defects caused by common failures existing in digitalized instrument and control systems based on CPU technology in nuclear power plant, the FPGA technology has been introduced in diversity system as the back up protection system in nuclear power plant. Considering the difference in operating mechanism between FPGA and CPU technologies, the critical issues and solutions for applying FPGA in diversity system are put forward in further. The result of analysis verifies the correctness and feasibility of this application, and it is indicated that FPGA technology will definitely become the developing direction of DCS in NPPs.
