| 摘要: |
| 核电是构建清洁低碳新型电力系统的重要基础，但新型电力系统存在惯性水平降低、抗扰能力减弱等特征，这些变化对核电机组涉网运行带来的风险尚不清晰。为此，首先归纳了新型电力系统的特征，介绍了新型电力系统对核电机组运行稳定性的影响。其次，介绍了核电厂的基本运行特性及其安全运行准则，分析了核电机组与电网间的相互作用效果。然后进一步探讨了新型电力系统下核电机组的涉网风险，并介绍了基于不确定性分析的风险评估方法。最后，针对新型电力系统下核电机组的涉网风险展开讨论并提出优化运行建议。研究可为新型电力系统中核电机组的涉网运行安全提供理论支持和实践指导。 |

| Abstract: |
| Nuclear power is an important basis for building a clean and low-carbon new power system. However, this emerging power system is characterized by reduced system inertia and diminished disturbance resilience, introducing unclear risks to the grid-connected operation of nuclear power units. This paper first summarizes the characteristics of the new power system and discusses its influence on the stability of nuclear power units. Then, it introduces the basic operation characteristics and safe operation principles of nuclear power plants, while the interaction between nuclear power units and the power grid is also analyzed. Furthermore, this paper explores the potential grid-integration risks faced by nuclear power units under the new power system and presents risk assessment methods based on uncertainty analysis. Finally, it discusses strategies to mitigate these risks and proposes recommendations for optimal operation. This study aims to provide theoretical support and practical guidance for ensuring the safe operation of nuclear power units in new power systems. |
