中文摘要
      电力系统是强非线性的动态大系统,在运行中总要受到外部干扰和内部干扰的影响,从而对其稳定运行造成严重威胁.本文针对带有TCSC单机无穷大母线系统的三阶鲁棒模型,在考虑阻尼系数未知及系统受外部扰动的情况下,将自适应backstepping方法与非线性L2增益干扰抑制理论融合,构造出系统的存贮函数,并获得非线性自适应鲁棒控制器及参数替换律.所得控制器不仅能够保证系统状态有界,而且能够有效抑制干扰对系统输出的影响.通过对单机系统的仿真结果表明采用该方法的控制器优于传统的控制器.
英文摘要
      As nonlinear dynamic and large scale systems,electric power systems in operation are always influenced by the external and internal disturbances;and thus the serious threat to stable operation of systems exists.In this paper,based on the three-order robust models of single machine-infinite bus system with thyristor controlled series compensation (TCSC) and under the conditions that systems have unknown damping coefficient and external disturbances,the storage functions of the system are constructed by integrating nonlinear L-two gain disturbances attenuation theory smoothly into backstepping design methodology.A nonlinear adaptive robust controller and a parameter update law are obtained.The derived controller can not only ensure that the system states are bounded,but also can attenuate the influences of disturbances on system output.The simulation results on single machine suggest that the controller designed by this methodology was superior to conventional controller in performances.
