Reduction of Reactive Power for Power Saving Utilization at Home Power Lines

Ondrej Krejcar, Robert Frischer


In recognition of the ever increasing energy prices, reactive power compensation is getting more and more into the forefront. Climate protection and energy is one of the most discussed issues of current policy. Production of electrical energy from primary sources to its consumption occurs however in the process of losses. Although these total losses are obviously only a small portion of the current-dependent losses in electricity transmission, the final absolute value of those losses go to billions of kilowatt. Part of the current-dependent losses in networks raises inductive reactive power from the operation of common appliances. Many home electric appliances like refrigerators, deep-freezes, washing machines, washers, pumps, etc. produce vaste energy called reactive power, which can be reduced. This technique can lower electricity consumption (from 10 to 30% - different by countries). Current possibilities of devices for reduction of reactive power for home usage are only very limited with high price. Paper deal with a development of miniaturized solution based on 32b MCU (Micro Controller Unit) with wireless communication unit and independent powering circuit. We mentioned need of a very fine measurement of an input voltage and current as well as remote monitoring option.
