| 摘要: |
| 研究了晶闸管控制的分级串联电容换级时的暂态过程。采用编程仿真的方式，对单级电路和多级电路分析后，提出了晶闸管开关最佳接入时刻为被短接电容电压为零时；分析了阻尼电阻、电感对暂态过程的影响以及它们之间的参数配合；采用电容分级式可控串补策略可大大降低可调电感容量及成本。高压输电线路分级电容可控串补的应用可提高系统的稳定性。 |

| Abstract: |
| The transient process of graded series capacitor during grade change controlled by thyristor is studied. By programming simulation,the single-grade and multi-grade circuits are analy-zed,and it is the best moment for thyristor to switch on when the voltage of capacitor to be shorted is zero. The influences of the damping resistance and reactance on transient process are researched,as well as the proper match of their parameters. The graded series capacitor in TCSC(Thyristor Controlled Series Compensation) lowers the adjustable inductance capacity and the cost. Its application in high-voltage transmission lines may improve system stability. This project is supported by the National Natural Science Foundation of China (50477056). |
