Abstract: The modern structure of power supply system is characterized by an expanding non-linear load which has a pulse nature of electrical energy consumption, a wide range of higher harmonics and a low electromagnetic compatibility with the supply mains. Unsymmetrical load due to single-phase power-consuming electrical receivers has also a negative impact on the electrical power supply system which leads to unbalance current flow in a neutral wire. In this regard, the power consumption modes experimental analysis was carried via measuring with the aid of certified devices “Energomonitor-3.3T1” and “C.A 8335” as well as by means of simulation modeling using matlab simulink software package. Experiment and simulation results confirmed the presence of the higher harmonic components of currents and voltages as well as the unbalance of loads caused by the presence of non-linear electrical receivers and unbalance of loads per the phases. It was drawn the conclusion that for improving the power factor within the microdistrict electrical power supply system as well as improving electric power quality, it is necessary to develop such compensation methods that would simultaneously solve the problems of improving the electric power quality in case of random changes in load parameters within the microdistrict electrical power supply system.
