| 摘要: |
| 提出了一种新的适用于电力系统机网暂态过程数值仿真的有阻尼绕组同步电机模型。通过采用“旋转因子法”对同步电机的电压方程组进行差分化，成功地消除了因旋转电势引起的，存在于同步电机直轴电压方程和交轴电压方程之间的耦合，导出了相互解耦的直轴和交轴瞬态等值电路。文末的算例通过比较该模型与EMTP模型的仿真结果，证明这种新模型是正确的，其仿真算法比常用的EMTP算法更精确、更稳定。 |

| Abstract: |
| A novel model of synchronous machine with damping winding for the transient analysis of power systems is presented.With rotation factor method,the differential voltage equations of a synchronous machine,which are coupled between d axis component and q axis component,are dispersed into de coupled different equations while the synchronous machines is described by its de coupled d axis equivalent circuit and q axis equivalent circuit.The model is more accurate than EMTP's model and is very convenient for practical use.An example is presented to illustrate its accuracy and stability. |
