摘 要: | 高压直流输电(HVDC)系统的附加控制器可以改善系统的稳定性。针对多馈入高压直流输电系统,应用非线性控制理论中的状态反馈线性化法设计了直流系统的附加控制器。首先建立了多馈入高压直流输电系统的数学模型,然后推导出稳定控制规律,推导过程中考虑了2条直流系统附加控制的相互影响,最后以一个3机和2条直流线路构成的系统为例进行了仿真研究。研究结果表明:与传统控制器相比,该控制器能更好地改善系统的稳定性。

Abstract: | The additional controller high-voltage direct current transmission (HVDC)system can improve the stability of the system. Feed into the high-voltage direct current transmission system, the author of this paper, application of state feedback linearization method of nonlinear control theory additional controller design for DC system. First established more feed into the mathematical model of high-voltage direct current transmission system. And then derive the stability control rule, were considered in the derivation process two additional control of DC system influence each other, and finally to a three machine and two DC lines constitute a system as an example to carry on the simulation research. The results show that compared with the traditional controller, the controller can better improve the stability of the system. |
