Generating peak power demand savings, reducing the load on existing circuits, mitigating equipment risks and gaining transformer and generator capacity for future expansions.
Following power quality and compliance concerns, Toowoomba Regional Council engaged Hexeis to deliver a comprehensive turn-key power control solution that delivers long-term business value. Commencing with a power quality study, the comprehensive scope of engineered works included active harmonic filter system sizing, design and construction of a 300-amp Accusine+ Active Harmonic Filter facility, including building a new switch room and integration into the existing electrical system.
THE BRIEF
<p class="rteBlock">Toowoomba Regional Council engaged Hexeis to analyse the electrical power quality for compliance and threats to equipment reliability at the Wetalla Waste Water Reclamation Facility located in Queensland.</p>
THE SOLUTION
<p class="rteBlock">By harnessing the Hexeis portable power quality meters connected via our 4G server, the Hexeis team was able to quickly complete a site power quality analysis. Data showed that the power harmonics and power factor needed to be controlled to reduce power demand charges, improve power efficiency, and to meet Energy Queensland's connection agreement requirements. </p><br><p class="rteBlock">From this analysis, Hexeis successfully tendered to size, design, build, and install an Accusine+ Active Harmonic Filter (AHF) through its group construction and electrical capabilities at NRG and supply partner, Schneider Electric. Works included a purpose-built, temperature-controlled panel room to house the AHF unit, extending the main switchboard, and installing a standby generator. Our experienced team expertly managed power outages and implemented robust risk mitigation strategies to deliver the project while day-to-day plant operations continued seamlessly and safely. </p><br><p class="rteBlock">The installation was a highly technical process that required detailed electrical engineering, planning, coordination and execution to create a hospitable environment for the AHF unit, which is essential for optimal performance. Measurement and analysis following the installation shows this has been achieved.</p><br>
THE RESULTS
<p class="rteBlock">Following its installation, the Hexeis Active Harmonic Filter solution has provided:</p><br><ul class="rteBlock defaultList"><li>Reduction in monthly peak demand charges by 10%</li><li>Improved power factor from 0.82 to 0.95 - a 15% improvement!</li><li>Cleaner power by reducing unwanted harmonics/interference (Total Harmonic Distortion). Results show a reduction of THDi from 30% to 3% - a 90% improvement! The correction has significantly reduced the distortion in the electrical system, leading to better performance and longer equipment life.</li><li>Reduced the load on the existing transformer and generator, allowing future site expansions without an expensive electrical system upgrades.</li><li>Reduced power drawn from the grid, resulting in ongoing kVA tariff savings.</li><li>Compliance with Energy Queensland’s connection agreement.</li></ul><br><br>
