Abstract

In the thesis project developed a system of electric pumping station pumping unit residential complex water. The task of control system is to keep the set pressure steady in water main of the housing estate, maintain stable pressure within 24 hours, maintain energy-saving pressure control, prevent from increased and reduced pressure in water supply network In accordance with the output data the motor and frequency transformer were chosen, power supply of pumping station was rated, structural scheme of control system was developed, parameters of dynamic links were determined. Regulator of pressure was synthesized. The study of dynamic modes of control system was carried out by means of modeling in a computer. Efficiency analysis of implementation frequency regulation of pumping unit drive was carried out and measures to ensure safety labor conditions at a pumping station were elaborated. The economic issues and issues of safety and emergency action.
