Mathematical model development of automated pumping station electromechanical complex

The aim of this work is to develop a mathematical model of a electro-mechanical pumping station complex, including low-voltage frequency converter, step-up and step-down transformers, sine-wave filter and choke at the frequency converter (FC) output to control a high-voltage induction motor (IM), and the hydraulic system including electric centrifugal pump and pipe fittings. The simulation was performed in the programmable software based on electro-hydraulics analogy, which adequacy is confirmed by the transient processes graphs, as well as characteristics of the pump and pipe-hydraulic resistance.
