不平衡电网条件下NPC变换器的扰动定制超螺旋控制

This article presents a high-performance control scheme for three-level neutral-point-clamped converters under unbalanced grid conditions. In the current tracking loop, a reset adaptive positive/negative sequence observer is developed for effective grid voltage synchronization, ensuring accurate reference current calculation and flexible objective adjustment of active/reactive power. For the volta...
