提出了一种新型静止无功发生器 (ASVG)自适应控制器用于抑制发电机功角振荡 ,该控制器采用最小方差控制策略 ,运用一种较为简单的参数预估器得到ASVG脉冲宽度控制角 ,以改变 ASVG交流侧电压值 ,从而给系统提供无功补偿。根据系统工况 ,控制器参数由自适应规律自动调整。仿真结果表明 。
In this paper,an adaptive controller is presented for advanced static var generator(ASVG) ,which utilizes a detuned minimum variance control strategy and uses a simplified parameter estimator structure for generating pulse- width control angle to change AC voltage of ASVG,thus it can change var provided for the power system.The parameters of the controller are adjusted by adaptive law according to the system state. The simulation results show thatitcan improve the transient stability and voltage stability of power systems effectively.
