Abstract

The persistently growing non-linear loads utilization in recent times produces harmonics that can negatively impact the performance of a power system network. Harmonics causes the system’s voltage and current signals distortion and in effect results in power loss increase. This study analyzed the series-shunt passive filter (SeShPF) impact on harmonic distortion-power loss interaction in an electrical distribution network. The mathematical equations for determining the system’s voltage, current and voltage-current total harmonic distortion (THDV, THDI and THDV-I) along with the active power loss were formulated. The modelling and simulation of the Federal University of Agriculture, Abeokuta (FUNAAB) electrical distribution network for 250-seater computer laboratory facility which was used as a test case before and after the application of SeShPF were done in MATLAB/Simulink R2023a environment. The THDV, THDI, THDV-I and active power loss for each simulation scenario were determined. The obtained results showed that without the use of SeShPF on the case network, the THDV, THDI and THDV-I were 21.71, 30.43 and 37.38%, respectively, while the active power loss was 9703 W. In contrast, the application of SeShPF on the network reduced the THDV, THDI and THDV-I to 0.06, 0.22 and 0.22%, respectively, whereas the active power loss was minimized to 35 W. This study showcased the SeShPF as a potential candidate for mitigating electricity distribution network harmonics and power loss.
