This paper presents a simulation model to evaluate phase voltage unbalance in rural local low voltage power lines. The voltage asymmetry has been evaluated by the voltage asymmetry coefficient value [alpha]U2, being one of the essential parameters characterizing quality of electric energy supplied from a low voltage power line to the consumers.
A simulation program facilitating to determine values of the chosen parameters characterizing electric energy quality ([delta]U - voltage deviation, [alpha]U2 - voltage asymmetry coefficient) supplied to the rural consumers has been built on the basis of the elaborated model of a low voltage power line (LV). The simulation program representing a computerised realization of the model has been written...
