Harmonic analysis of power in an electrohydraulic complex with nonlinear processes in the pipeline system

A possibility of application of power harmonic analysis method to an electrohydraulic complex with nonlinear processes in the pipeline system is demonstrated. It is determined that nonlinear processes in a hydraulic network, caused by cavitation self-oscillations, result in periodical stationary oscillations of power, are accompanied by increase of its variable component. To assess the processes of energy conversion in the electrohydraulic complex it is proposed to use indices based on determination of root-mean-square values of power.
