基于虚拟电感与直流升压控制的双馈变速抽水蓄能机组低电压穿越方法

This article proposes a novel low-voltage ride-through (LVRT) control strategy for doubly-fed variable-speed pumped hydro storage (VS-PHS) units. Unlike conventional LVRT approaches for doubly-fed induction generators (DFIGs) that mainly rely on crowbar circuits or virtual inductance control, the proposed strategy combines rotor-side virtual inductance with dc-link voltage boosting, fully leveragi...
