A Comparative Study on AC/DC Analysis of an Operational Low Voltage Distribution System

Cihan KATAR, Cengiz Polat UZUNOGLU


By the recent innovations brought by the improvement of technology, we are witnessing the rapid advancements of devices and systems working with direct current (DC). In the near future, the digitalizing world will continue to improve and the need for DC based devices will be increased beyond doubt. Today’s electrical grid strictly dependent on AC-DC rectifiers for a variety of devices which are used in residential buildings. Each AC-DC conversion process means additional power losses and signal quality deteriorations for the network. In addition, networks which are fed by batteries and renewable sources such as solar panels, wind turbines, etc. are suffering from conversion based power losses.  In this respect, the idea of switching to DC on the low voltage side of the networks has become intriguing subject. In this study, the applicability and efficiency of the Low voltage direct current LVDC concept for low voltage distribution systems is discussed and a sample LVDC distribution system is analyzed. In this operational residential application ETAP program is employed for comparison of different voltage levels such as 110 VDC, 250 VDC, 320 VDC and conventional 220/380 VAC. Comparative analysis is conducted for safety regulations, voltage drops, current carrying capacities, power consumption and harmonic calculation. In this respect applicability, possible drawbacks and future aspects of LVDC systems are interpreted.
