摘要：核电作为清洁、低碳、能量密度高、经济性好，不受季节和气候等因素影响的能源，除短暂的换料大修外，能以额定功率长期稳定运行，满足基荷电源可靠、经济、充足和清洁四大要求，具有极为重要的政治、经济、生态、科技战略价值，是能够替代化石能源基荷电源的最佳选择。近年来我国大力发展核电事业， 而核电DCS（Distributed Control System，分散控制系统）是核电站的“神经中枢”，承担着核心监控、安全保护及运行管理职能。在核电DCS中，通信模块是保障系统安全运行和数据高效传输的核心组件。随着我国核电技术的发展，为满足我国三代甚至四代核电站技术的需求，对核电DCS的性能和可靠性要求越来越高，而在设计我国自主研发的核电DCS“和睦系统”的过程中，通信模块RE超标的问题时有出现。本课题结合当前电力电子技术，在核电DCS通信模块设计阶段进行研究分析，该研究对我国后续核电DCS系统的开发具有借鉴和指导意义。

Abstract: Nuclear power, as a clean, low-carbon, high-energy-density, and cost-effective energy source that is not affected by seasonal and climatic factors, can operate stably at rated power for a long time, meeting the four requirements of reliable, economic, sufficient, and clean base load power sources, except for brief refueling and major repairs. It has extremely important political, economic, ecological, and strategic technological value and is the best choice to replace fossil-fuel- based baseload power sources. In recent years, China has vigorously developed its nuclear power industry, and the nuclear power DCS (Distributed Control System) is the "nerve center" of nuclear power plants, responsible for core monitoring, safety protection, and operation management functions. In the nuclear power DCS, the communication module is the core component that ensures the safe operation of the system and efficient data transmission. With the development of nuclear power technology in China, in order to meet the needs of third- generation or even fourth-generation nuclear power plant technology, the performance and reliability requirements of nuclear power DCS are becoming increasingly high. However, in the process of designing China's independently developed nuclear power DCS "Harmony System", it was found that the communication module would have the problem of REexceedance the standard. This project combines current power electronics technology to conduct research and analysis during the design stage of the nuclear power DCS communication module. This research has reference and guiding significance for the development of subsequent nuclear power DCS systems in China.
