An Investigation of Power Quality Problems in a Remote Mine Site in Papua New Guinea

Investigation and monitoring of power quality is necessary to maintain accurate operation of sensitive equipment. Electrical power systems of mines with their sophisticated technology will always have a need for monitoring power quality to ensure that critical processes are operating efficiently. Two of the most common power quality problems, Voltage Sag and Harmonics are investigated for a Remote Gold Mine in Papua New Guinea. Field power quality data is collected by PQNode(R) and then simulated using the PSCAD (R) / EMTDC (TM) software. Results are then compared with appropriate standards and subsequently correct mitigation techniques are investigated
