Abstract

A method of the energy flows in the different physical nature systems’ electrically driven turbomachines analysis has been offered. Energetic relationship between the Bond Graph models of the induction motor and centrifugal pump has been established. The study of a single electro hydro mechanical process of turbomachines work has been conducted.

At the current stage of scientific progress, solving the complex technical systems’ operational calculation and optimization problem of mostly carried out by computer simulation. Therefore, the necessity of the electrically driven turbomachines computer-based models' development such modeling techniques that would not require special skills in the programming and made it possible to analyze the mutual influence of the different physical nature subsystems' components of the object's dynamic behavior have been arisen.

As a result of the research, numerical set and graphical depending on the instantaneous values of the electric motor power, mechanical shaft power of the hydraulic machine and hydraulic power on the pump discharge pipe have been received. The efficiency of energy conversion in each individual area of the turbomachine, based on the obtained results, has been analyzed. In the future, it will enable to develop and implement energy saving measures in the electrical complexes of the industrial enterprises.
