Gritsenko K. The automated energy saving control of a water-supply pump station

Subject of research - the automated control of a water-supply pump stations. Goal of research - increasing the economic efficiency of the work of a water-supply owing to applying methods of the energy caretaking at the control of the operational mode of the pump station. Methods of the theory of hydraulic circuits, graph theory, methods of optimization was used. The topological model of the technological scheme of a pump station, which is general purpose for any pump stations, is designed. The method of the energy caretaking at the control of operational mode of a pump station is worked out, which one differ from known methods and allows to achieve the purpose of energy caretaking owing to discretely-continuous control and forecast of the water consumption of customers. Has received further development the method of formation of a technological task for a pump station on the basis of requirements of customers and statistical analysis of deviations of water consumption from the value that was calculated. The method of coordination of operational modes of pumps with variable speed drives of a pump station is worked out, which one in comparison with present methods allows more effectively in relation of energy consumption to execute a technological task. Practical importance - are designed functional structure of the automated control system of a pump station and her algorithmic maintenance. The results, obtained in dissertation, are accepted to usage by enterprise "Gorvodokanal" in Sumy for the control of a pump stations. Sphere of results usage - organizations, which ones design or exploit systems of water- supply.
