Single Tuned Filter Design for Mitigating Harmonic Distortion in (30 KV) ALTAHRER Substation

Abstract

Nowadays, due to the fast growth of electronic devices, harmonic issues have become a main matter for current day electrical operators. Some of the causes of harmonics are: a) ripples in voltage waveform of machines, b) flux distortion in the synchronous machines, c) transformer magnetizing currents, d) non-linear loads such as static power converters, arc furnaces, and e) static-var compensators as suppliers of continuously variable var sources. The harmonic filtering is one of the solutions for preventing the worrying harmonics from entering the rest of the system. There are basically two types of filters: i) passive, where the filter components are passive elements such as resistor, inductor, and capacitor, and ii) active, where the filter has a controlled current or voltage source. This peper introduces a single-tuned passive filter to minimize the harmonic distortion of AL-TAHRER substation (30KV). The offered filter and studied system modeling are built by ETAP software. Results show the effectiveness of the proposed filter in mitigating total harmonic distortion of studied system
