Optimization of Protection and Regulation Strategies to Maintain System Stability in the Presence of Symmetrical Voltage Dips in DFIG Wind Turbines

Abstract

Symmetrical voltage dips, are frequent in power systems, impacting wind turbines, especially DFIG-equipped ones. This study focuses on optimizing protection and regulation to ensure stability during these dips. It examines DFIG behavior during voltage dips, proposes effective control strategies, and validates them through simulations. Results confirm successful dip mitigation without major turbine stability or power output disruptions. These findings enhance DFIG-based wind turbines' reliability and performance, offering insights for manufacturers and operators to improve wind energy systems
