The results of the analysis of transient and technological processes of the irrigation pumping station of the first lift, taking into account the negative starting effects on the synchronous electric drive, are considered. The analysis and review of the ways of regulating the performance of the units of the irrigation pumping station of the first lift are made, and the main difficulties of the existing methods of regulating the pump supply are revealed. Computer simulation of starting modes of high-voltage synchronous electric motors with direct and soft start, where soft starter was used for soft start, was carried out. The simulation took into account the changes in the currents of all phases of the electric motor, the electromagnetic torque, the motor speed, the effective value of the current, as well as the static torque. The introduction of semiconductor soft starters for electric drives of high-power pumping units has been substantiated.
