This paper presents the minimization of 075MVA, 11/0.45KV power distribution system harmonics using High Voltage Direct Current Link (HVDC) and three phase harmonic filter. In the study the HVDC was used to control load flow stability while the harmonic it induces on the power system was controlled with three phase harmonic filter. The three HVDC was developed with 12 pulse thyristor converted and rectifier while the filter was developed with shunt elements. These were implemented on the distribution system using Simulink and the performance evaluated based on the Nigerian Electricity Regulation Commission Standard (NERC). The result when tested showed that the HVDC was able to control the flow of active and reactive power via the 6 pulse thyristor components, while the harmonics was reduced to the satisfaction of the NERC standard for power quality in distribution network. Keywords: Voltage, Current, distribution system, Thryristors, HVDC, NERC, filter, harmonics
