| 中文摘要 |
| 在直流输电系统中,换流器速度的提高可以快速调整直流线路上的功率,从而提高交流系统的稳定性,增强输电能力.本文用动力系统的方法研究了直流输电系统的稳定性.在自治与非自治两种情况下对直流输电系统的数学模型作了理论上的分析,设计出了相应的反馈控制,该控制可以对直流换流器中的触发滞后角与触发越前角进行快速有效的调节,进而让换流器中直流电流指数地趋于稳定. |
| 英文摘要 |
| In power system,the power of the direct power transmission line can be adjusted quickly by increasing the speed of the converter so that the stability of the system can be improved.The stability of high voltage direct current(HVDC) system is studied by the method of dynamic system in this paper.The mathematical model of the direct power transmission is analysed under the autonomous and non-autonomous cases.The feedback control is then designed,the trigger lag angle and trigger leading angle of the direct current conveter can thus be adjusted effectively under the control,and the direct current of converter is thus exponentially stabilized. |
