Abstract. The article considers the main requirements for pumping stations, in particular, for methods of regulating the water supply at the first lift pump unit. A description of the pumping unit and equipment is provided. The article provides a comparison of the types of the main drive units of pumping stations. It also provides a rationale for
the choice of electric drive system between classical asynchronous and synchronous electric drives, as well as a system
with a field regulated reluctance machine (FRRM) with a comparison of energy indicators. A description and substantiation of the control system work are also given. The articles provide the technical characteristics of the motor parameters and the daily flow rate of the station fluid. The optimal method for regulating the power supply system was chosen
based on research. A mathematical model of the device which implements the chosen control method is presented.
The results of mathematical modeling are presented in the graphs. A graph of the transient process is given in the case
of changing speeds depending on the required fluid supply. Conclusions about the efficiency of the system are drawn
and further action plans are outlined.
