The paper analyzes modern trends in modelling the centrifugal hydraulic load of the pumping station electric drive. It was found that a very simplified approach to the representation of one of the inextricably linked subsystems (hydraulic or electromechanical) is mostly used, which significantly reduces the possibility of a complex analysis of the processes in its individual elements. Models based on this approach can be effectively applied to solve highly specialized tasks and do not always give a clear idea of the state and modes of all the elements of the subsystems.
The paper analyses the contemporary state of the electric drive hydraulic load modelling in the pumping stations’ electrotechnical complex applications. It was found that in the vast majority of cases, mathematical models do not allow taking into account the specificities of fluid pumping and its consumption at the same time with a balanced degree of detail.
