超临界二氧化碳布雷顿循环控制策略研究综述
摘要：超临界二氧化碳(supercritical carbon dioxide，S-CO2)布雷顿循环在以第四代核能和太阳能为代表的清洁能源高效利用领域具有巨大发展潜力，而合理可靠的控制策略是保证S-CO2布雷顿循环系统安全、稳定、高效、灵活运行的关键。调研总结了S-CO2布雷顿循环控制特点，并对不同应用场景下S-CO2布雷顿循环相关控制策略进行了总结和对比。结果表明，S-CO2布雷顿循环控制包括运行状态控制、叶轮机械控制、热源控制等，变负荷控制策略主要有容积控制法、透平旁路控制法、透平进口节流阀控制法、压缩机转速控制法等。分析结果可为相关发电领域S-CO2布雷顿循环控制策略选择提供参考。
Abstract:Supercritical carbon dioxide(S-CO2) Brayton cycle has great development potential in the field of efficient utilization of clean energy represented by fourth-generation nuclear energy and solar energy. A reasonable and reliable control strategy is the key to ensure the safe, stable, efficient and flexible operation of the S-CO2 Brayton cycle system. This paper summarized the characteristics of S-CO2 Brayton cycle control, and summarized and compared the S-CO2 Brayton cycle control strategies under different application scenarios. The results show that the key control strategies of S-CO2 Brayton cycle include running state control, impeller machine control, heat source control, etc. The variable load control strategies mainly include volume control, turbine bypass control, turbine inlet throttle control, compressor speed control, etc. The analysis results provide a reference for the selection of S-CO2 Brayton cycle control strategies in related power generation fields.
