Power Quality Improvement Using Hybrid Filter in Multiphase Conversion

Pooja Yadu | Siraparapu Satyanarayana

Abstract: The electric power demand is continuously increase with the advancement of technology at their exponential rate. Now a days quality power is necessary for continuous operation of consumer appliances for these three phase supply is sufficient but due to potential benefit of multiphase (more than three phase) in transmission system. Multiphase electrical drive system is incredibly vital in analysis within the last decade. The quality of power delivered to the end user is affected by various external and internal factors as variations in voltage and frequency, fault occurrence, outages etc. The main affect caused by these problems is the presence of harmonics. This leads to the overheating of the equipment, insulation failure and over speeding of motors etc. to overcome these problems is to filter out these harmonics. This work will be explain about various filtration techniques with their advantageous properties and comparison. In this paper work a conversion of three phase to a multiphase. The connection output gives five phase supply from three phase and can be used in application acquiring five phase supply. The connection scheme is elaborated by using simulation to prove the viability of implementation but these conversion increase the total harmonic distortion (THD) value. In order to reduce these harmonic and to improve the power quality of the power system can be achieved by using a hybrid filter which is a combination of both active and passive filter. The proposed model is simulated with MATLAB /SIMULINK and result are presented in graphs.
