Analysis of Harmonics in Goma Power Distribution System

Non-linear load is the major element in a network to rise harmonics due to its characteristics. Harmonics are creating a lot of problems and disturbing the electrical network such as malfunction of electrical devices, efficiency reduction as well as reduction of the effective lifetime of electrical devices. This paper proposes a study of harmonics and analysis of filter to be implemented in order to remove higher-order harmonics and total harmonic distortion of current in the electric power systems of Goma that can be a key for proper connection to a smart grid for any network and to move to it in Goma network. Simulation results in Matlab/Simulink are presented and compared for the distorted IEEE-519 - 15kV without filtering and with a passive filter as well as an active filter.
