On the basis of the obtained results of mathematical experiments the rational scheme of power supply and connection of the pump unit, structure and algorithm of functioning of the microcontroller system of automatic control of modes of pumping of liquid in all range of change of productivity of pump station at stabilization of pressure at the inlet of the pipeline are substantiated. It is shown that the use of the developed circuit, system and algorithmic solutions in comparison with the accepted basic variant allows to improve the indicators of electrotechnological efficiency of the considered PSS-PS complex. Mathematical models of dynamic modes of centrifugal hydraulic loading of the electric drive of the pump station, and also - synchronous and asynchronous pump units are developed.
