一种用于三相同步旋转坐标系锁相环的复数型电压归一化方法

Voltage normalization is widely used in phase-locked loops (PLLs) to keep their dynamic and stability decoupled from the grid-voltage amplitude. In this article, a complex-type voltage normalization method is proposed for three-phase PLLs. First, the performances of the PLL under the conventional voltage magnitude normalization method and the $d$-axis voltage normalization method are reviewed. Whe...
