Abstract

We study the physical processes occurring in electrotechnical complexes with turbo mechanisms and pipelines. The strategy for improvement of the methods and means is defined for analyzing the operating modes of electrotechnical complexes with controlled pumping stations for energy efficiency raising of their operation. Subsystem classification of such complexes is proposed; an element-wise and general analysis of the current state of their modeling is carried out. It is shown that, in spite of a large number of works devoted to this topic, a systematic approach to mathematical modeling of processes occurring in such complexes has not been developed to date. In connection with the greatest potential for energy saving of powerful complexes, the necessity of creating an effective means of their analysis is justified, particularly, in the steady-state regimes. Based on the formalized approach, a mathematical model of the generalized electrotechnical complex of the power supply system of a pumping station has been developed. The model was successfully tested in the calculation of stationary modes of power supply systems for oil pumping station and a sewerage station. It is advisable to use the proposed model for analyzing the modes of both operating and projected objects, as well as for creating automatic control systems for such objects.

Keywords: complex, station, pump, centrifugal, pipeline, hydraulic analogy grid, system, power supply, drive, engine, control, mathematical model
