The contemporary state of the modelling of the pump station’s electric drive in a complex with its centrifugal hydraulic load has been analysed. It was found that most studies focus either on the modelling and development of automatic control systems for the asynchronous electric drive of pumps or on the optimization of performance indicators of the station as a whole. Besides, usually only one of the subsystems of a pumping station (or an electrically-operated pump unit) is modelled with a good degree of detail: either electromagnetic or hydraulic.

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.
