摘要
核电站反应堆保护系统采用通信的方式实现重要保护信号的传输。为提升传输可靠性,以反应堆保护系统通信设计方案为研究对象,针对通信路径中的单一通信板卡故障风险,提出基于和睦系统的核电站专设安全设施驱动功能通信链路的设计优化方案。从通信故障后果、系统可靠性数据、性能指标和硬件变更范围方面,对设计优化方案的效果和可行性进行理论分析,并搭建实物样机进行测试验证。理论分析和验证结果证明通信设计优化对于减少通信设备故障的影响具有实用效果,有利于保障核电站的安全和经济性。该研究为后续不同堆型核电机组的建设,以及在役核电机组的优化改造提供了重要参考。
The reactor protection system of nuclear power plant adopts communication to realize the transmission of important protection signals.To enhance transmission reliability,the reactor protection system communication design scheme is taken as the object of study,and the design optimization scheme of the communication link for the drive function of nuclear power plant engineered safety feature based on the FirmSys is proposed in view of the risk of failure of a single communication board in the communication path.The effect and feasibility of the design optimization scheme are theoretically analyzed in terms of the consequences of communication failures,system reliability data,performance indexes,and the scope of hardware changes,and physical prototypes are built for testing and verification.The theoretical analysis and validation results prove that communication design optimization has practical effects on reducing the effects of communication equipment failures,which is conducive to safeguarding the safety and economy of nuclear power plants.This study provides an important reference for the subsequent construction of nuclear power units of different reactor types,as well as the optimization and transformation of in-service nuclear power units.
