摘　　要：讨论了一种新型的低温核供热站数字化保护系统的设计方案，这一方案对保护系统信号采用了并行处理技术（由以微处理器为核心的软件处理单元和以通用阵列逻辑芯片为核心的硬件处理单元构成），以设备的多样性为手段，从根本上克服一般数字化保护系统由软件引起的共模失效问题，明显提高了系统的可靠性。A scheme of digitized Reactor Protection Systems(RPS) is discussed in this paper.An advanced parallel processing method,consisting of microprocessor based unit and GAL(General Array Logic) based unit,has been applied to the design,which would eliminate the common mode failure of current digitized RPS through using diverse equipments,and be expected to improve the reliability of RPS.
