Power model of an electrohydraulic complex with periodic nonlinear processes in the pipeline network

Abstract

An equivalent circuit of an electrohydraulic complex taking into account periodic nonlinear processes in a pipeline network is proposed. It is shown that the use of the method of harmonic analysis of hydraulic power makes it possible to single out variable components generated by cavitation phenomena, to perform frequency analysis of power processes in the hydraulic system. A power model of an electrohydraulic complex is developed on the basis of equations of power harmonic components energy balance between the source of hydraulic supply and hydrosystem elements. A possibility of the use of a power model in problems of identification of hydraulic complex parameters, when nonlinear hydrodynamic processes are developed in the pipeline, is proved.
