数字化仪控技术在核电厂的推广，为计算机化规程系统（CPS）在以APl000为代表的三代先进压水堆中的应用提供了技术基础。本文对计算机化规程系统的结构、功能和特点进行了描述，CPS作为先进的规程系统，不仅将运行规程以电子化的形式显示在电脑屏幕上，而且同时能监测和处理电厂参数，为操纵员提供规程执行指导，并且显著提高了规程的执行效率。另外，本文还将APl000中的CPS与某M310；0H改进型核电厂的数字化规程系统进行了比较，并结合实际CPS的本土化以及存在问题进行探讨。“,”With the tendency of digitalization in instrumentation and control system of nuclear power plants, APIO00, as well as other advanced PWRs, is provided with the technical basis for the application of CPS （computerized prcrature system）. This papor makes a brief introduction on CPS construction and function. CPS, as an advanced procedure system, does not only have the function of electronic indication for operation procedures, but also have the ability to monitor plant data, process the data and then present the status of the procedure steps to the reactor operator. In addition, advantages of CPS compared with paper-based procedures and comparison with digital operating system of one M310 plus advanced nuclear power plant are described. Moreover, based on current situation, this paper offers several suggestions on CPS localization for Sanmen APIO00 nuclear power project. Besides, the last part of this paper discusses problems we might meet during the prcvess of CPS localization.
