This study evaluated and compared the performance of shunt passive filter (SPF) and shunt active filter (SAF) in mitigating harmonic distortion in an electrical distribution network of a typical bottling company, 7-Up Industry Plc in Ibadan, Nigeria. The distribution network layout was modelled and simulated with and without SPF and SAF in MATLAB/Simulink software environment. The voltage and current total harmonic distortions (VTHD) and (ITHD) were determined. The voltage and current waveforms of the network without filter were distorted indicating harmonics presence. The VTHD and ITHD under no filter condition were estimated as 6.084 and 19.790%, respectively. Application of SPF and SAF on the network minimised the VTHD from 6.084 to 0.7802 and 1.311%, giving an improvement of 5.304 and 4.773%, respectively in voltage harmonics minimization over the no filter condition. Similarly, ITHD was mitigated from 19.790 to 2.448 and 4.163% with the use of SPF and SAF on the network, producing an enhancement of 17.342 and 15.627%, respectively in current harmonics reduction compared to no filter case. This study established that shunt passive filter exhibited a superior performance over shunt active filter and hence, more appropriate for harmonics mitigation on 7-Up Industry Plc distribution network.
