数字化反应堆保护系统典型问题分析及改进

Analysis and Improvement of Typical Problems of Digital Reactor Protection System

作为首次采用Tricon数字化平台实现的核电厂反应堆保护系统,方家山核电厂保护系统体现了数字化技术的强大优势,但也不可避免地遇到一些问题。通过对方家山核电厂反应堆保护系统自商运以来的运行维护经验进行总结,归纳出几类典型问题,并通过实际案例进行深度剖析,提出合理可行的改进措施及建议,为数字化平台在其他核电厂设计、调试、维护提供十分重要的指导和借鉴意义。

As the first nuclear power plant reactor protection system using digital platform Tricon, Fangjiashan Unit 1&2 proves the powerful advantages of digital technology, but also certainly some problems. This paper summarizes the experience of maintenance of Fangjiashan Unit 1&2 reactor protection system since business operation, describes some typical problem and actual cases, and analyzes the root cause of these problems in detail. It gives feasible measures and suggestions for improvement, these suggestions are important for the designing, commissioning and maintenance of similar units reactor protection system.
