摘要
对于包含基于自换向绝缘双极型晶闸管 (IGBT)逆变器的静止补偿器 (STATCOM) ,提出了一种非线性控制策略。基于该控制策略 ,静止补偿器能够保证系统电压稳定在给定值附近 ,而且在提供无功补偿时具有理想的暂态性能。同时该控制策略具有对主要参数扰动的鲁棒性。仿真和实验结果证实了该控制策略的有效性。
This paper presents a nonlinear control scheme for static synchronous compensators (STATCOM ) consisting essentially of a self com mutated IGBT inverter.To obtain a fast dynam ic response,a partial decoupling, an inverse model- based loop and a state feedback control are proposed to achieve asymptotic set point regulation. With the control law,the com pensator is able to stabilize the power system voltage around a prescribed value and to deliver the reactive power with a desired transient performance.Robustness properties with respectto variations in the main param eters are demonstrated.Sim ulation and experimental results confirm the analytical design.
