Research of operation of electrotechnical complexes of electric centrifugal pumps units for variations in external temperature effects

The article investigates the functioning of the electrotechnical complex of the electric centrifugal pump installation in case of variations in external temperature influences. A mathematical model of the analyzed complex is created taking the thermal nonstationary processes into account. It is also proposed to build an electromechanical system with an adjustable submersible electric motor with a subblock of parameter identification and a block for the estimation of state variables. This will allow considering external temperature influences during the control.
