Abstract:
In medium voltage supply systems, most loads commonly used are current-driven, leading to increased neutral current, unbalance, harmonics distortion, harmonics resonance, and low power factor. These problems can adversely affect the neighbouring loads and consumers in the distribution network. This research article presents a novel comprehensive approach to address these issues using a simple analytical method. The study considers a test network consisting of a three-phase, 380 V supply with different percentages of unbalanced composite loads. The proposed solution comprises three main parts. Firstly, a passive compensator in delta and star configuration is designed to minimize the unbalance and the power factor improvement. Secondly, the index of harmonics distortions is obtained from the harmonics analysis of the network. Thirdly, based on evaluating individual harmonics distortion (IHD) in all phases, a frequency scan is conducted for the selected harmonics in the network. The series LC network in star configuration is modified by appropriately detuning its frequency. The results are verified against the recommended harmonics values per IEEE 519 – 2014. The test network is simulated in MATLAB Simulink to obtain the harmonics spectrum and frequency scan results.
