一种用于三相电压源变换器暂态稳定性提升的双环频率前馈锁相环

A dual-loop frequency-feedforward phase-locked loop (DLFF-PLL) is proposed in this article. The proposed structure achieves angle and frequency tracking without integrator-based loop compensator commonly used in the conventional synchronous reference frame PLL. A dual-loop structure is proposed for tracking frequency and phase, respectively, where a feedforward filter provides the identified frequ...
