The article presents information on optimization of steady state regimes in power supply systems in order to minimize power losses. The following tasks were formulated and solved: engine parameters were determined; the steady state of the power supply system was calculated. Statistical characteristics of power losses in asynchronous and synchronous motors and transformers were obtained. Investigations have been carried out for the ore mining and processing enterprise. On the basis of the obtained universal model, a software package has been designed to perform computational and experimental research in order to obtain static characteristics of power losses and loads in the power supply system and to determine the character of variation of these characteristics.
