Performance and Comparison of Harmonics Using Active Power Filters and DVR in Low-Voltage Distributed Networks

The objective of this paper is to figure out the harmonic deviations and suppress the harmonics in a power system due to nonlinear loads coupled at common coupling point (PCC). Harmonics are the major index for low power quality of the distribution system which may also effect the life expectations of the power converters. Passive harmonic moderation approach has better solutions in power converters which gives distinct harmonic accomplishments at a system level where plenty of units are allied in parallel nearer to point of common coupling. There are various modes for harmonic moderation techniques present in a system, but based on operation and excellence usage of the system the shunt active power filter (SAPF) and dynamic voltage restorer (DVR) methods are considered. This paper provides significant approach to the performance of DVR and SAPF and various compensation accomplishments which are used to evaluate the harmonics and its effect on nonlinear loads by using MATLAB/Simulink.
