Comprehensive Modeling and Analysis of Stator Turn-to-Turn Short-Circuit Faults in a DFIG

Abstract: With the gradual increase in high capacity doubly fed induction generators (DFIGs) in recent years, turn-to-turn short-circuit (TTSC) faults have become a greater threat. Notably, owing to ...

Design-Oriented Small-Signal Stability Assessment of Grid-Following Inverter-Based Resources Based on Virtual Dynamic Short-Circuit Ratio

Abstract: Small-signal instability may occur when parallel grid-following inverter-based resources (IBRs) are connected to a grid with low strength, i.e., a weak grid. In such a weak grid, changes in ...

Here's Why A Simple Fresnel Lens Makes Traffic Lights Safer

Fresnel lenses are designed so their light can be pointed in just one direction, meaning drivers in a lane may see only the ...
