Design of Active Filter for Reducing Harmonic Distortion in Distribution Network

Power transmission and distribution systems are designed for operation with sinusoidal voltage and current waveform in constant frequency. Power electronic control devices due to their inherent non linearity draw harmonic and reactive power form the supply mains. The wide use power electronic equipment with linear load causes an increasing harmonics distortion in the ac mains currents. Harmonics component is a very serious and harmful problem in the distribution system. The main adverse effects of harmonic current and voltage on power system equipment are overheating, overloading, perturbation of sensitive control and electronic equipment, capacitor failure, communication interferences, process problem, motor vibration, resonances problem and low power factor. This paper describes the modelling of active filter with synchronous d q reference frame theory for harmonic compensation in distribution systems. The case study is carried out at Hlaingtharyar township distribution system. The model is implemented for harmonic analysis from simulation using a Matlab Simulink with the THD values obtained by practical measurement.
