Abstract: ProtachukO.V., Kasha L.V. (supervisor). « Automation of pumping setting for plumbing of cottage settlement”». Master’s thesis. - Lviv Polytechnic National University, Lviv, 2020. Extended abstract Introduction and first chapter of the master’s qualification work is devoted to the problems of modern water pumping stations, their use in small and medium volume utilities.Based on the analysis the main tasks of the master’s work are formulated, namely to get acquainted with the process and technology of water supply.Electric elements make choices that ensure efficiency of the system; develop a functional scheme of automatic control system (ACS); to carry out modeling and research of statics and dynamics of SAK by means of the personal computer. The second section of the master’s qualification work we carried out an overview of different kinds of pumping systems and types of pumps used in them. As a result, it was found that the installation should provide pressure regulation Water network [1], in order to reduce energy costs, water consumption and to minimize the amount of water and the size of the installations and equipment used by water. In the third chapter, we describe our pumping unit and analyze how to control the motors of electric drives of pumping units. It was found that the greatest advantage in our case management system is based on the frequency converter with rectifier [2] and AES on IGBT-transistors with scalar PWM modulation, which we will use in our pumping plants. The fourth chapter is devoted to the calculation of the electric system, determination of the main parameters of the automated CS and its characteristics. In the fifth chapter we conducted a mathematical description of blood pressure, which is part of the electric [4]. This section also received block diagrams of computer-aided design, which then allow using CAD to simulate the processes of our plant. In the sixth chapter of work the automated control system of the pump installation for cold water supply of cottage towns is developed. When designing the automated control system and selecting the element base - the main selection criterion was the availability of components of the electric drive, ie the ability to freely purchase them in Ukraine, obtaining technical documentation and warranty service [4]. The structural scheme of the automatic control system is developed in the seventh chapter, in accordance with the selected elements [3,4].The simulation and analysis of dynamic ACS characteristics by means of the personal computer is carried out in the end of master’s thesis. Study object – pumping station for water supply of the cottage town. Scope of research – processes of the automated electric drive of the pump installation of water supply. Goal of research - increasing the energy efficiency of the pumping station for water supply of the cottage town. Availability of electric drive components and small investments during electric drive automation.
