基于反推方法，研究了带有静止同步补偿器的单机无穷大系统的大扰动抑制问题。提出了一种新的基于外部扰动最大化的极小极大扰动抑制方法，有效地降低了扰动上界估计和不等尺度估计带来的扰动抑制的保守性。目的是保证STATCOM系统具有良好的鲁棒性和对大扰动的不敏感度。研究了具有短路接地故障和机械功率扰动的单机无穷大系统。仿真结果表明，该控制方案能有效改善电力系统暂态稳定的动态过程。与传统的非线性控制器相比，该控制方案对大扰动具有更大的优势，控制器的设计过程简单直观。
The large disturbance attenuation problem of the single machine infinite bus system with static synchronous compensator is considered based on the backstepping method. A new minimax disturbance attenuation method is proposed based on the maximization of the external disturbances, and it is used to reduce effectively the conservativeness of the disturbance attenuation, which is brought by the estimation of the upper bound of the disturbance and the inequality scaling. The purpose is to ensure the good robustness and insensitivity to large disturbances of the STATCOM system. The single-machine infinite-bus system with the short-circuit ground fault and the mechanical power disturbances is researched. Simulation results show that the control scheme can effectively improve the dynamic process of the transient stability of the power system. Compared with the conventional nonlinear controller, the control scheme has more advantages for large disturbances, and the process of controller design is simple and intuitive.
