This paper presents a Simulink simulation model of an active power filter based on a rapid harmonic current detection method. Active power filters are devices designed to mitigate harmonic interference in power systems by detecting harmonic currents and providing real-time compensation responses. The simulation employs advanced signal processing algorithms, including Fast Fourier Transform (FFT) or Instantaneous Power Theory implementation, to achieve precise harmonic extraction and generate corresponding compensation currents through PWM-controlled voltage source converters. Simulation results demonstrate that this model effectively filters out harmonics in power systems, improving power quality and protecting electrical equipment from harmonic-related disturbances. The implementation features real-time harmonic tracking capabilities with minimal computational delay, ensuring stable system performance under dynamic load conditions.
