Object of study - the process of automatic regulation bahatoahrehatnyh pumping installations. The aim - to improve pumping efficiency by improving existing electromechanical automatic control pumping units based on frequency-controlled induction motors and use extreme method of control for different types of connections pumps. Methods and apparatus - the fundamental tenets of the theory of automatic control, electric theory, theory turbomehanizmiv methods of the theory of extremal systems, computer simulation and experimental study. Theoretical and practical results - extreme control principles and mathematical tools to describe them, allowing to modernize existing bahatoahrehatnyh pumping plants to improve their efficiency; developed approaches to the assessment process and coordinate pump mathematical formalization that can be used for widely distributed systems stabilize pressure or costs in order to reduce capital by organizing bezdatchykovoho control. Novelty - the method of management efficiency pumping units based on the theory of extreme systems for serial, parallel and mixed types of connection units, thus improving the energy efficiency of electromechanical automation bahatoahrehatnyh pumping, the first time set a property for bahatoahrehatnyh systems provide operating point with maximum efficiency of a pumps with extreme control algorithm by only changing the engine speed without stabilization performance and the analytical conditions for the existence of this property, found the combination of simultaneous optimization of the pump on the criterion of the maximum efficiency of minimizing losses in the drive induction motor, unlike the maximization only pump additionally improve energy efficiency and proposed law search terms maximum efficiency pump with indirect evaluation based on nonlinear dependence of the performance of the pump speed received for working points with maximum efficiency. The degree of implementation - communal enterprise "Zhitomir production department of water and sanitation '(Zhytomyr). Areas of use - water supply.
