| 摘要: |
| 基于系统主导模式下功角稳定裕度关于各节点负荷参数的灵敏度分析，提出广域电力系统负荷模型的校准导航，以区分系统负荷模型的主导校准区域和主导校准参数，并分析节点的稳定群属特征。基于静态、动态负荷比例参数和负荷功率初值，讨论电力系统负荷模型主导校准区域的分布规律及其影响因素，结果表明该类参数的主导校准区域分布主要取决于扰动的位置和各节点负荷有功功率的大小，仿真和实际算例验证了其正确性。提出先选择主导校准区域，再对其中负荷节点进行分类，并对同类负荷节点采用相同的模型参数进行统一校准的方案，以提高广域电力系统负荷模型校准的效率和精度。 |

| Abstract: |
| Based on the analysis of power-angle stability margin sensitivity to the load parameters of different nodes in system dominant mode，a calibration navigator is proposed for the load model of wide-area power system to distinguish the dominant calibration areas and parameters of system load model and analyze the stability clustering characteristics of load nodes. The law of dominant calibration area distribution and its influencing factors are discussed based on the static and dynamic load ratio parameters and initial load powers，which shows that，the dominant calibration area distribution depends mainly on the location of disturbance and the active power of nodal load. Its correctness is verified by simulation and practical example. A unified scheme of load model calibration for wide-area power system is proposed to improve its efficiency and accuracy，which selects the dominant calibration areas first，classifies their load nodes，and calibrates the load nodes of same type with the same model parameters. |
