The possibility of using reversible operating modes of hydraulic and electric machines in the problems of improving the controllability of an electrohydraulic complex is shown. The schemes of energy balance in pumping and turbine operating modes of hydraulic machines are given. A mathematical description of the four-quadrant characteristics of the pumping unit is proposed. The complete characteristics of the pump operating on the pipeline network with back pressure, when the direction of rotation of the pump electric motor was changed and there was reverse of the liquid in the hydraulic system, are obtained. A structural diagram of a system for active regulation of pumping unit parameters based on the use of hydro turbine units or reversible hydraulic machines is proposed.

Pokazano możliwość użycia odwracalnego trybu pracy maszyn hydraulicznych i elektrycznych w polepszaniu sterowności zespołu elektrohydraulicznego. Podane zostały schematy równowagi energii w trybie pompowania i pracy turbinowej maszyny hydraulicznej. Dla jednostki pompowanie z czterokwadrantowym trybem pracy opracowano modele matematyczne. Otrzymano finalne charakterystyki działania pompy i sieci rurociągowej z ciśnieniem wstecznym w warunkach zmiany kierunku obrotów napędu elektrycznego pompy i cofania płynu w systemie hydraulicznym. Zaproponowany został diagram parametrów aktywnej regulacji jednostki pompowania, wykorzystujący jednostki turbin wodnych lub odwracalnych maszyn hydraulicznych.
