Pumping stations that provide fluid transportation by pipeline are significant consumers of electricity. Energy overruns due to sub-optimal modes of operation of individual high-power units or sub-optimal number of simultaneously operating less powerful units are quite significant and can have a significant impact on overall energy consumption. Energy overruns at pumping stations also lead to significant overruns in electricity grid elements.

Mathematical model of unit, which includes asynchronous motor, clutch and pump is proposed. The model includes non-linear differential equations of electromagnetic effects in motor and motion equations of mechanical units, which generates uniform system. Calculation of transition process is developed by numerical integration of this system.
