NONLINEAR MODEL OPTIMIZATION PARAMETERS OF POWER UNITS A PUMP STATION PUMPING A WATER SUPPLY SYSTEM
An optimization mathematical model has been developed to increase the energy efficiency of a pumping station pumping the water supply system using a cascade method of controlling the amount of water supplied by a system of identical, parallel-connected centrifugal pumps. The problem of experimental determination of the curve of the random process of water consumption of a residential area has been solved. The procedure of multicriteria optimization of electricity costs for the provision of the water supply process, the value of efficiency and the number of power units of the pumping station has been carried out using numerical methods of mathematical programming. The optimization procedure allows you to choose the type of pumps, their number and the optimal mode of operation, taking into account the stochastic nature of the water consumption process.
