Harmonic emission of grid connected back to back arrangement of rectifiers in distribution networks

Abstract

Emission of Harmonics plays a potent role in distribution systems. The intention of this paper to inspect the harmonic level by the implementation of UPQC (Unified Power Quality Conditioner) at distribution system level. This system offers indirect power quality (PQ) pay of the voltage and also the supply current. The harmonic performance of small grid with respect to different power electronics and grid parameters. Latest studies suggest that the UPQC has high efficiency and better Power quality. This system is very simple and uncomplicated. The equipments used in this system always monitors the harmonic level on the source side by considering the voltage magnitude and supply current. By employing this system, the THD value is very low, injected voltages or currents gets nearer to sinusoidal. The execution of the planned system is simulated in MATLAB/Simulink surrounding.
