Ensuring continuous and reliable operation of a distribution center

Challenges at the customer’s distribution center

The customer’s distribution center is a complex and large warehouse. It is 37,000 m² and has a lot of state-of-the-art high-tech equipment which makes the promise to customers of fast delivery possible. All the conveyors, scanners, and automated logistic machinery need stable power with as little harmonics as possible.

The most problematic loads of the distribution center are switched-mode power supplies, cranes, lifts, and uninterruptible power supplies. Cranes and lifts are usually fed by VFDs, so together these devices produce and aggravate harmonics and phase imbalance in the network.

Harmonics make energy usage less efficient and may even cause equipment failures, while phase imbalance usually leads to a shorter lifetime of equipment due to increased temperature in motor windings. Merus Power took on the challenge of improving the distribution center power quality together with our local partner Ampcontrol.

Our Merus^® Solution

Merus^® HPQ was installed on the site by our partner Ampcontrol. The system was designed for outdoors to maximize the capacity of the distribution center. The purpose of the installed Merus^® Hybrid Power Quality system is to ensure reliable operations by mitigating harmonics, correcting phase imbalance, and compensating fundamental reactive power. This will improve power factor, THD, and the overall power quality of the network.

Results after installation

After installing Merus® HPQ, the customer experienced improvements in power quality, energy efficiency, and operating costs. The system effectively mitigated harmonics, corrected phase imbalance, and compensated reactive power, resulting in a reduction in total harmonic distortion and an improvement in power factor. Overall, the installation of the Merus® HPQ provided the customer with a reliable and cost-effective solution to ensure the smooth operations of their automated distribution center.
