Abstract:

Independent wind farms with Doubly Fed Induction Generators (DFIGs) often experience major overvoltage, harmonic distortion, and other power quality concerns, as well as transient disturbances [1]. This study implements a D-STATCOM system combined with Phase-Locked Loop (PLL) control to address voltage stability and enhance dynamic reactive power compensation [2]. The PLL-based control locks the system voltage, enabling synchronous operation and effective harmonic filtering [2]. A phase controller is incorporated within the D-STATCOM to further improve system response to increase damping against frequency variations and slow voltage magnitude changes. The created system is modeled in the MATLAB/Simulink platform, simulated, with the capability of DFIG-based wind farms to reduce power quality issues studied. Results demonstrate significant improvements in voltage stability, a marked reduction in harmonic content, and enhanced overall power quality performance [3]. These findings reinforce the potential of advanced D-STATCOM configurations in supporting reliable, high-quality power delivery from independent renewable energy sources [4].

Keywords:
