Sotnyk М. Energy processes in electromechanical systems of networks of water supply

Work is aimed to the further development of the theory of analysis of the interconnected processes of energy transformation in separate components of electromechanical systems of water supply networks by method of electric analogies on the basis of their electric models development. As the basic power element of a hydraulic network in work is investigated electromechanical system (EMS) which consists of the driving electric motor, the pump and devices of a supply of liquid from accumulative tanks. Functionally it is the multi-stage converter of energy in which transformation of frequency, of quantity of phases, one type of energy in another is carried out also imposing of power streams occurs. It is the basis for representation EMS electric models which output part is the rectifier of electric energy. On the basis of the analysis of electromagnetic processes in electric models of electromechanical systems of water supply networks requirements to strategy of modernization of their components are formulated. The developed method is simpler for the user, productive and complex, in comparison with existing. It allows to determine expected indicators of functioning of water supply network with the modernized equipment by technical and power characteristics. Data on introduction of the developed method of power efficiency increase of power supply systems of technological consumers are provided in networks of water supply of the enterprises of Ukraine.
