Abstract: In this Master’s dissertation the analysis of methods of the water supplement pumping stations aggregates control is carried out. The methods of optimizing the work of pumping stations to increase their energy efficiency and efficiency of installations are investigated. The main reasons for the use of an adjustable electric drive for controlling pump units are considered. The modern control system on the basis of the logic controller and frequency converters, which during the development can be easily adapted for the necessary initial data of the water supply system, is developed. Actuality of theme. In the last two decades, the adjustable asynchronous electric drive has developed so much that it has completely supplanted the synchronous drive and the DC drive from many areas of industry. This is primarily due to advances in power electronics and microprocessor technology, based on which frequency converters have been developed that control asynchronous short-circuited motors, surpassing other drives in terms of energy and dynamics. With the growth of the population in cities, the issue of increasing living space through the construction of new housing estates and neighborhoods is acute. As a result, the need to develop support systems is growing. Also, today there are many residential complexes that need to be modernized in some places of all water and energy supply systems due to the long service life, which can lead to equipment failure at any time. The purpose and objectives of the study. The main task in the development of systems of engineering equipment that meets the requirements of comfort in different climatic conditions is to identify reserves for saving water and fuel and energy resources, taking into account the requirements of environmental management. The purpose of the developed system is to minimize the interference of the human factor in the operation of the pumping station. It is also an energy efficient 8 and economical solution in terms of electricity consumption. This effect is provided by the use of modern methods of control of pumping units and multifunction controllers to optimize the operation of the system as a whole. In the complex of urban planning engineering equipment of settlements is one of the most important components and includes heat supply, electricity, water supply, drainage, gas supply. Thanks to the efficient operation of these systems, the needs of the population in comfortable living, work and leisure are met. Scientific novelty of the obtained results. 1. Possible ranges of change of water supply and pressure to the consumer at work of pump installation using two frequency-regulated pump units are established. 2. The optimal energy-efficient modes of operation of the pumping station are set. 3. A system of automatic control of pumping units of the water supply station has been developed. The practical significance of the obtained results lies in the possibility of their use for the design, development (or modernization of existing) pumping stations of residential buildings in order to efficiently use energy resources and improve the performance of hydraulic systems in general.
