THE STEADY-STATE MODES OF THE COMPLEX "ELECTRICAL SUPPLY SYSTEM - PUMPING STATION"

Abstract

The level of energy saving pump stations depends on several factors, including the hydraulic
pump load themselves. Energetically the most effective use of combined (discrete-continuous) flow control
pumps. Analysis of experimental mode records coordinates powerful pumping stations showed that they
slowly change over time (excluding start-up mode, emergency stop equipment and processes). This justifies
the separation of long modes and to classify them as quasi-stationary of which requires the establishment of
appropriate means. Despite the universality of dynamic modeling, it is not always equally useful for the
analysis of steady state regimes. Based on the results of mathematical experiments, the expediency of improving the steady-state regimes of the complex "power supply system - pump station" is justified. The structure is synthesized and a mathematical model of an energy-efficient power supply system and discretecontinuous automatic control of the steady-state regimes of such a complex is developed. Using the designed
of schematic, system and algorithmic solutions makes it possible to improve the performance of complex
electro-technological efficiency. Complex mathematical model, based on the composition of models are inextricably linked its subsystems, has powerful functionality for research performance electro-technological
efficiency action of various disturbing effects and control and of schematic changes. The results can be used
in further studies to expand the functionality mathematical models
