| 摘要: |
| 根据静止无功发生器SVG(Static Var Generator)的结构特点，建立了相应的微分方程。考虑到实际系统的非线性周期性时变系数的影响，将逆变器的外部电气性能，用直流量与交流量之间的矢量关系进行了线性化处理，并根据劳斯一胡尔维茨稳定性判据得出了电力电子技术应用时的非线性控制参数与系统参数之间的稳定性关系，根据稳定性的表达式得到了静态稳定结果。 |

| Abstract: |
| Electrical differential equations are derived according to the characteristics of SVG (Static Var Generator) configuration. Considering the effects of periodic variability of non-linear system parameters,the external electric performance of inverter is linearized with the linear vector relationship between ac and dc. The stabilization conditions among system and control parameters under the power electronic applications are got with Routh-Hurwitz criterion. The static stabilized outputs are obtained with derived stabilization relationship. |
