摘要：

针对含晶闸管控制串联电容器装置的单机无穷大电力系统, 考虑摩擦阻尼系数不确定及受外部未知干扰的情况, 基于非线性自适应动态面控制方法, 设计了鲁棒控制器, 同时得到了系统不确定参数的自适应更新律以及系统稳定运行的充分条件.采用该方法避免了传统自适应backstepping法中对虚拟控制输入的反复求导, 克服了计算量过大的缺点.数值仿真结果表明, 所设计TCSC非线性自适应动态面鲁棒控制器在系统动态响应和不确定参数的估计性能方面优于传统的自适应backstepping鲁棒控制器, 提高了电力系统的动态稳定性.

Abstract：

For friction damping coefficient uncertainty in single machine infinite bus power system with thyristor controlled series compensation device,which is affected by unknown external disturbances,we design the robust controller based on nonlinear adaptive dynamic surface control method.Meanwhile,adaptive update law of uncertain parameters and sufficient condition for the stable operation of the system is obtained.Using this method can avoid repeated derivation of the virtual control input in the traditional adaptive backstepping method,and overcome the disadvantage of excessive computing.Numerical simulation results show that TCSC nonlinear adaptive dynamic surface robust controller designed in this paper performs better than the traditional adaptive backstepping robust controller in dynamic response of system and estimation of uncertain parameter.The dynamic stability of power system is improved.
