APF Model MATLAB Simulink Implementation for Power Quality Improvement

Simulation was conducted based on the APF model implemented in MATLAB Simulink. This model serves as a crucial tool for power quality improvement, utilizing advanced control algorithms to address power quality issues caused by nonlinear loads. The simulation implementation employs instantaneous power theory (p-q theory) for harmonic detection and pulse width modulation (PWM) techniques for current compensation. Simulation results demonstrate the effectiveness of the APF model in enhancing power quality, specifically showing significant reduction in voltage distortion and harmonic components, along with improved power factor correction. The model features real-time harmonic compensation through controlled switching devices and includes proportional-integral (PI) controllers for precise current tracking. Key Simulink blocks used include three-phase voltage source, nonlinear load components, harmonic measurement blocks, and PWM signal generators for inverter control.
