摘要：核電作為清潔、低碳、能量密度高、經濟性好，不受季節和氣候等因素影響的能源，除短暫的換料大修外，能以額定功率長期穩定運行，滿足基荷電源可靠、經濟、充足和清潔四大要求，具有極為重要的政治、經濟、生態、科技戰略價值，是能夠替代化石能源基荷電源的最佳選擇。近年來我國大力發展核電事業， 而核電DCS（Distributed Control System，分散控制系統）是核電站的“神經中樞”，承擔著核心監控、安全保護及運行管理職能。在核電DCS中，通信模塊是保障系統安全運行和數據高效傳輸的核心組件。隨著我國核電技術的發展，為滿足我國三代甚至四代核電站技術的需求，對核電DCS的性能和可靠性要求越來越高，而在設計我國自主研發的核電DCS“和睦系統”的過程中，通信模塊RE超標的問題時有出現。本課題結合當前電力電子技術，在核電DCS通信模塊設計階段進行研究分析，該研究對我國后續核電DCS系統的開發具有借鑒和指導意義。

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.
