<p>Presence of harmonics in the power grid is a major power quality problem. Various techniques are available to compensate both current and voltage harmonics present in the supply. Conventional schemes are based on filtering technique where fundamental current component is separated from distorted load current. This paper deals with simulation and implementation of Synchronous Reference Frame theory based control scheme for shunt active power filter utilized to compensate for the harmonics drawn by a typical nonlinear load. Simulation is carried out in MATLAB/SIMULINK and hardware implementation is done using dSPACE. Results are presented and discussed to validate the performance of the algorithm in real time.

P. Keerthy, Maya, P., and Dr. Sindhu M. R., “An adaptive transient tracking harmonic detection method for power quality improvement”, in TENSYMP 2017 - IEEE International Symposium on Technologies for Smart Cities, 2017.[Abstract]


Among various power quality issues, presence of harmonics in voltage/current waveforms is a major one. It becomes prominent in smart grids, where renewable energy sources are integrated through power electronic interfaces. Efficiency of harmonic mitigation techniques depends on accurate estimation of fundamental and non-fundamental parts of the waveform. In this paper, an adaptive harmonic estimation technique based on empirical wavelet transform is proposed. This technique is applied to source current waveform measured from a sample power system with nonlinear load. During transients, the algorithm is found to be capable of tracking the change in the fundamental frequency with good time-frequency localization. Simulation of the algorithm is carried out in MATLAB/Simulink. Results are presented and discussed. © 2017 IEEE.

With the advent of semiconductor technology, the usage of nonlinear loads in the power system has increased tremendously thereby creating different power quality issues. Shunt active power filters are used to eliminate current harmonics and also for reactive power compensation, which are major power quality issues. In this paper, simulation study of fuzzy logic for shunt active filter is presented. Synchronous reference frame theory is used for current control and fuzzy logic is used for DC link voltage control. The output from current control and voltage control is used for generating switching pulses for shunt active filter using a hysteresis controller. The proposed scheme is simulated using MATLAB/SIMULINK. Results are compared with a conventional control scheme based on PI controller. © Springer India 2016.
