"Green technologies" elements by the individual residential buildings internal electrical networks operation

The article discusses the research results on the internal electrical networks operation of two independent individual residential buildings with a 0.38 kV voltage three-phase electrical input energy. It is established that these electrical networks operation is characterized by a significant currents and voltages unbalance level, which leads to a quality standards violation and electrical energy additional losses increase. When using the computer program "ModulHous", which algorithm is based on the developed calculation methods, the currents and voltages unbalance calculation was performed. With the use of the MATLAB graphics editor technology, the obtained changes visualization in the currents and voltages unbalance has been implemented. The obtained diagrams analysis made it possible to establish the unbalance power consumption level and its impact on the internal power supply efficiency of the individual residential buildings. A special balancing device is proposed that automatically minimizes unbalancing flows in the internal individual dwellings electrical network. The developed software made it possible to establish the using balancing devices efficiency to improve the quality and reduce electrical energy additional losses in the considered electric networks of individual residential buildings.
