Development of a Simulation Model of the First Rise Area of a Water Supply System with a Storage Reservoir

The article deals with the issue of creating a simulation model of the first rise area of the water supply system with a storage reservoir. The relevance of this problem is determined by the importance of uninterrupted and cost-effective functioning of the object in question, which is widely used in the economic activities of enterprises and localities. This paper implements a model of the first rise area with a single pump. The model consists of a frequency-controlled asynchronous electric drive, a centrifugal pump, an elevated pipeline, and a storage reservoir. The blocks of the model interact through the appropriate physical parameters. The structure of the simulation model is designed for use in conjunction with automatic performance control systems for first-rise pumps. The Simulink package of the Matlab software complex is used as a simulation modeling environment. To confirm the correctness functioning of the developed model elements, the results of a trial run of the model at parameters implemented in the laboratory conditions are presented. Comparison of the simulation results with the calculated and laboratory data, as well as the declared technical characteristics of the simulated devices, showed satisfactory convergence, which confirms the correctness of the methods used in the work.
