OPTIMISATION OF NEW TYPES OF ELECTROMECHANICAL CONVERTERS FOR MECHANISMS WITH FAN-TYPE LOADS

Abstract

Тhe article considers the main requirements for pumping stations, in particular, for methods of regula­ting the water supply at the first lift pump unit. A description of the pumping unit and equipment is provided. The artic­le provides a comparison of the types of the main drive units of pumping stations. It also provides a rationale for the choice of electric drive system between classical asynchronous and synchronous electric drives, as well as a system with a field regulated reluctance machine (FRRM) with a comparison of energy indicators. A description and substantiation of the control system work are also given. The articles provide the technical characteristics of the motor parameters and the daily flow rate of the station fluid. The optimal method for regulating the power supply system was chosen based on research. A mathematical model of the device which implements the chosen control method is presented. The results of mathematical modeling are presented in the graphs. A graph of the transient process is given in the case of changing speeds depending on the required fluid supply. Conclusions about the efficiency of the system are drawn and further action plans are outlined.
