第三代中国先进压水堆CEPR核电机组相比第二代CPR1000项目,在核电汽轮发电机的控制、保护、监测系统上首次采用了三代技术,在设备冗余、性能以及逻辑设计上都进行了优化,提高了控制和保护的可靠性。本文通过对比,对三代技术新特点进行了介绍和分析,为系统后续运行和维护提供参考。同时由于后续核电机组也将采用新的系统,本文能帮助同行更快速掌握新系统的特点。
Compared with the second-generation CPR1000 project, the third-generation China Advanced PWR CEPR nuclear power plant adopts the third generation technology for the first time on the control, protection and monitoring system of nuclear power turbine generator. Both of them are used in the equipment redundancy, performance and logic design Optimized to improve control and protection reliability. By contrast, this paper introduces and analyzes the new features of the three generations of technology, providing reference for the subsequent operation and maintenance of the system. At the same time as the follow-up nuclear power plant will also adopt a new system, this article can help colleagues more quickly grasp the characteristics of the new system.
