Оптимізація процесу транспортування стічних вод засобами електропривода в системах водовідведення великих міст

Abstract

In the master's qualification work the system of electric drive and control system of electric drives of the sewage pumping station was developed. The frequency converter is selected as the power converter. Driving motors have been calculated, their overload check and start capability tested. The structural scheme of the electric drive and the functional scheme of the work of the station have been developed. A mathematical model of the wastewater transportation system has been developed. An algorithm for optimal distribution of sewage flows between pumping stations has been developed. The program of control system operation is developed. Computer simulation tested the efficiency of the pumping station and the optimization algorithm.
