Power Quality Improvement of Distribution Network for Non-Linear Loads using Inductive Active Filtering Method

This paper proposes the comparison of Active Power Filtering (APF) and Inductive Active Filtering (IAF) which in turns improves the Power Quality for not only the distribution network i.e.; Public Grid but also the Non-Linear Loads i.e.; Power Supply systems. At first, main circuit topology for implementing IAF method which consists of Inductively Filtered Converter Transformer connected with non-linear Load and Fully Tuned Branch which can be controlled through the inverter. Initially the mechanism of the APF is done through the technical features. Based on this the mathematical model is built and equivalent circuit is established with the filtering mechanism for IAF method. Then the designing of the Controller loop of Fully Tuned branch is configured. For the three phase supply system, results are compared for APF and IAF. Hence the harmonics can be reduced. The Power Quality improvement of Distribution Network can be done for three phase diodes controlled by fully tuned branch is Simulated using MATLAB/ Simulink to make the grid current sinusoidal.
