Mathematical Modeling Of Multi-Units Pumping Station With Asynchronous Electric Drive Of Centrifugal Pumps

Abstract

Based on the system approach and the principle of electrohydrodynamic analogy, a formal- ized mathematical model of a generalized system of asynchronous centrifugal pumping units of a multi-unit pumping station with an asynchronous electric drive of centrifugal pumps was created. This model is easy to adapt to the specific configuration of the pumping sta- tion. A feature of the model is the use of such pa- rameters of the centrifugal pump, which are calculated directly through the geometric dimensions of its inter- nal elements, taking into account the dependence of these parameters on the physical properties of the work- ing fluid. Unlike existing models, this makes it pos- sible to take into account the influence of operational or emergency changes in pump parameters and opera- tional changes in the physical properties of the working fluid both on its pumping regimes and on the operation regimes of the electric drive directly during the simu- lation. The scope of use and ways of improving the developed model, as well as the direction of further re- search, are proposed.
