High-speed air intakes often exhibit intricate flow patterns, with a specific type of flow instability known as ?buzz?, characterized by unsteady shock oscillations at the inlet. This paper presents a comprehensive review of prior research, focused on un...

In the power transmission of doubly-fed induction generators (DFIGs), sub-synchronous oscillation (SSO) can occur due to the influence of series compensation capacitance and long-distance transmission. SSO not only affects the output of the DFIG but also...

According to the grid code specifications, low voltage ride-through (LVRT) is one of the key factors for grid-tied wind farms (WFs). Since fixed-speed wind turbines with squirrel cage induction generators (FSWT-SCIGs) require an adequate quantity of reac...
