100kW Grid Connected Solar System

Petro Min Engineers were engaged by Energy Savers WA for a grid connected 100kW solar system with the capability to export excess generated solar power into the Western Power network.

As part of the power quality monitoring during commissioning, a serious problem with high harmonic voltage and current was identified and PME provided assistance and engineering for a 250 Amp Danfoss Active Front End power filter.

This Danfoss unit not only reduced current harmonics to less than 3% Total Harmonic Distortion but spare capacity in the unit was used to improve the site power factor to better than 0.95 lagging.

PME provided the connection certification and commissioning for the system to meet Western Power’s Technical Rules requirements for an export capability for the 100kW solar system.
