Power Quality issues resulting from Energy Saving Initiatives- New Revenue Opportunity for the Building Automation Community

Energy saving and green energy initiatives are changing the energy economy for more carbon-free and cost-effective power production. However, the introduction of energy efficiency measures like LED lights, VFD (Variable Frequency Drives), EV (Electric Vehicles) charging stations and smart solar grids also pollute the power lines by introducing current and voltage harmonics, voltage/current imbalance and many other deleterious power quality issues. Therefore, with the adoption of energy efficiency measures, there is an increased need to analyze the resulting power quality since the measures may adversely impact expensive machines such as HVAC systems, pumps, motors, CT scanners, MRIs, and many others. It may also increase the fire hazards from the current imbalances. The consequences of resulting poor power quality from energy efficiency measures may outweigh any financial or practical gains of energy-saving projects. This paper shows one of such case studies done on an office building with five floors and having different offices in different floors. Click to continue reading the white paper.
