Latest Patents

Weidong Xiao holds a patent for a "Fault handling system for doubly fed induction generator." This system is designed to improve the Fault Ride Through (FRT) capability of DFIG-based wind turbines. The patent outlines a transient management system that utilizes a grid side converter (GSC) to introduce shunt and series compensation during normal operations and voltage dips. Additionally, a braking resistor can be incorporated to smooth switching transients and dissipate excess power from the GSC. The system employs positive and negative sequence controllers to provide a flexible control solution for both balanced and unbalanced fault conditions. The dynamics of the series compensation topology are analyzed using a small-signal linear model, allowing for the tuning of the controller to balance voltage regulation performance and transient stability margins. The design benefits from a low component count, a simple protection structure, and improved FRT performance, effectively compensating for disturbances in the electric grid.
