PS&C has noticed increasing interest for Power Conditioning equipment to support less traditional markets. It seems that a majority of the new inquiries for power quality systems and services are being generated from industrial facilities. In many cases, they are from facilities that have installed new equipment on production lines. Industrial Facilities are subject to a variety of power problems. The most common are equipment shutdowns (affecting both the older systems, as well as, the new ones), voltage sags (both on utility & inside the plant), and harmonic distortion (caused by Adjustable Speed Drives/ASD).
In addition, we have heard of instances from various utility companies where neighbors of industrial plants have called to complain about disruptions to their power caused by the plants across the street. How does this happen? In most cases, it’s because the Industrial Plants have replaced older processing systems with newer, state-of-the-art systems. And while the new systems increase productivity improve quality and lower costs, they can also cause unexpected problems within the electrical system. These problems can be anything from improper equipment operation to complete equipment shutdown every time there is a minor disturbance on the electrical system.
PS&C has been witness to end users who try a range of solutions with varying degrees of success. One was to install new, very large Automatic Voltage Regulators, harmonic canceling transformers, Power Factor Correction capacitors, and small static UPS systems. In some cases, these devices not only didn’t work, they actually ended up causing more problems. Other solutions included correcting facility grounding problems, installing Motor-Generators for voltage regulation, and/or isolation from the power source, and removing capacitors and installing Synchronous Condensers to correct power factor problems without the danger of creating resonance points.
Just as the benefits of Hybrid Rotary UPS systems have made to computer power protection, large rotary systems can be the best value in many industrial applications as well. Static UPS systems, TVSS’s, and traditional power protection devices have their place but rotary systems offer abilities and performance benefits that other technologies are unable to do.
