Estimation and Mitigation of Current and Voltage Harmonics in Distribution System Using Distributed Generation

M.Jegadeesan, N.Venkatesh

The power quality problem occurs due to the non-standard current, voltage or frequency, this result in disoperation of consumer equipment’s. So the present work is to identify the important concerns in this area and hence the measures that can improve the quality of the power are recommended. Harmonic analysis in the distribution system is absolutely necessary to study the behaviour of equipment connected to the non-sinusoidal system environment for designing, placing and sizing of distributed generation. IEEE 13-bus balanced distribution system is considered for analysis of harmonics. Harmonic analysis of the distribution system gives the harmonics spectrum which in turn it gives THD currents and THD voltages at many buses. Reduction of harmonics is performed by simulation using distributed generation. The simulation study shows the best performance of the distributed generation placement at/near the non-linear load buses. The balanced distribution system model is simulated using MATLAB/SIMULINK 2012 software with static and non-linear loads.
