| 摘要: |
| 使用相量测量单元（PMU）的实测数据，进行了大量的感应电动机负荷模型参数灵敏度分析，并从参数灵敏度的角度出发，提出了将灵敏度较小的感应电动机负荷模型参数固定，仅辨识灵敏度较大参数的方法。结合电网实际扰动仿真、暂态故障曲线Prony分析以及电网小扰动分析，使用综稳程序PSASP进行仿真分析，仿真结果证明了所提简化模型辨识的可行性和实用性。 |

| Abstract: |
| The parameter sensitivity of motor load model is analyzed with plentiful actual data measured by phasor measurement units. It is proposed to simplify the identification of motor load model by only identifying the model parameters with high sensitivity while fixing those with low sensitivity. Combined with the simulation of actual grid disturbance，Prony analysis of transient fault curve and small perturbation analysis of power net，the results of simulation with PSASP show the feasibility and practicability of the proposed method. |
