THE STEADY-STATE MODES OF THE COMPLEX

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 discrete-continuous 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.
