An observer based on an artificial neural network was designed. The observer determines the pumping unit performance depending on the operating point. Determination is based on the measured technological coordinates of the system and the pressure of the turbomechanism. Three neural networks were designed for three types of the productivity observer. The developed observer was investigated by the simulation method within different variations of disturbing actions, such as hydraulic resistance of the hydraulic system and geodetic pressure. A comparative analysis of three types of the productivity observer, built with using the pressure and different signals of the system with arbitrary change of hydraulic resistance was given. By the use of the pump unit efficiency observer, in addition to the results presented earlier, the efficiency of the productivity observer, which built with using different sensors, in water supply systems with two series-connected pump units, operating for filling the large tank, is 1 / 4 2020 N1 s10 researched. In the water supply system one pump speed is regulated, the other is unregulated. References 14, figures 5.

Purpose. Development of a water supply unit in the conditions of pressure control fed from a renewable source of electric energy with static compensator (STATCOM). Methodology. The research was carried out by the method of mathematical modeling in the application packages MATLAB SimPowerSystems and Simulink. The object of the study is a turbomechanism control system, which is powered by a wind turbine when regulating the voltage and realizes the pressure stabilization during the daily cycle of hydraulic resistance variations. The subject of the study is the structure development of a given level of pressure stabilization in the water supply unit. Findings. A mathematical model of a water supply control system powered by a wind turbine is presented. The unit tests the pressure at a given level in accordance with technological requirements. The nature of the variation in pump performance within the daily cycle of consumption when powered by a wind turbine, which in turn performs regulation using a static compensator, is studied. Originality. The system regulates the generated voltage by using a STATCOM, which allows you to maintain its level constant regardless of changes in the network hydraulic resistance. Practical value. Today, the use of alternative energy sources is becoming increasingly important. The developed conception will allow improving the existing water supply systems and designing new ones. It allows you to adjust the set level of pressure stabilization, while the output of generator is maintained constant under constant wind conditions.
