Abstract: One of the main operation modes that characterizes power quality in distribution networks is asymmetry of three-phase voltage system. Operation of an induction motor (IM) with disturbed voltage symmetry in the supply network can not be considered as a rated one. The system of voltages applied to the stator winding of IM under these conditions contains positive- and negative-sequence components. This worsens the performance characteristics of IM essentially. In order to balance the 0.38 kV network operation and enhance the efficiency of the three-phase electric motor operation it is suggested to use a special balancing unit (BU) that minimizes the negative-sequence components of current and voltage. The operation modes of the obtained system "supply source – induction motor – balancing unit" are simulated within the MATLAB software package of applied programs, which allows one to assess the impact of low quality of power on the operating characteristics of the elec!
tric motor and the efficiency of the balancing unit to increase the "durability" of the motor under the asymmetrical power consumption.
Keywords: voltage asymmetry ; coefficient of additional power losses; parameters of balancing unit ; the negative- and positive- sequence currents.
