| 摘要: |
| 仿真计算了在暂态稳定问题中，负荷中感应电动机比例对极限切除时间的影响，并用负荷动态实测参数进行河南全网的稳定计算，与以往使用的近似负荷模型计算结果进行比较，结果表明，使用实测参数的河南电网商丘地区的电压稳定问题更加严重，而其他地区的稳定极限则由于实测负荷的电动机比例较小而有所提高。 |

| Abstract: |
| The influence of induction-motor ration on switch-off limit in transient stability problem is simulated and calculated.The stability of Henan provincial power system is calculated using measured dynamic load parameters and compared with the stability calculated using approximate load parmeters.The comparative result shows that the voltage stability of Shangqiu area calculated using real load parameters becomes more serious,while the stability limits of other areas are im-proved because the measured induction-motor ration is less. |
