The article gives information on optimization of steady-state regimes of power supply systems in order to minimize power losses. The following tasks were set and solved: motor parameters were determined; the steady-state regime of PSS was calculated. Static characteristics of power losses in asynchronous and synchronous motors and transformers have been obtained. Researches have been carried out for ore mining and processing. On the basis of the obtained universal model, a software package has been designed to perform calculation and experimental researches to obtain static characteristics of power and load losses in PSS and to establish the patterns of variation of these characteristics.
