| 摘 要： | 根据保护系统的技术发展及最新的电子技术，并结合２００ＭＷ核供热站的特点，提出了一种改进的保护系统设计方案。该设计方案在信号转输环节应用电压／频率变换技术，在信号处理环节应用无软件数字化技术，在逻辑符合环节应用通用阵列逻辑（ＧＡＬ）技术和微处理器系统互为冗余的结构，克服了为２００ＭＷ核供热站原来所设计的保护系统在通信、自检及信息显示等方面的不足，同时也从设备多样性角度探索解决数字化保护系统中软件失效引起的共模失效问题的方法。

| Abstract: | According to the development of reactor protection systems (RPS) an improved concept design of RPS for 200 MW nuclear heating plant (NHP) was covered in this paper. Some of advanced features, including V/F based signal transport, no software digital processing, redundant decision logic consisting of microprocessor based system and GAL (general array logic) based system, have been incorporated into the improved RPS, which would have advantage over the previous 200 MW NHP's RPS for overcoming such weakness as difficult in communication, poor man machine interface and insufficient online diagnose, and be expected to eliminate the common mode failure of current digitalized RPS through using diverse equipment. |
