Abstract
An electromechanical power transmission chain comprises an electrical machine (101) connectable to a combustion engine and to a mechanical load, a storage circuit (104) for storing electrical energy, an electronic power converter (109) for transferring electrical energy between the storage circuit and the electrical machine, and a control system (110) for controlling the combustion engine and the electronic power converter. The control system controls the electronic power converter to transfer electrical energy from the storage circuit to the electrical machine in response to a peak-load situation where power demand of the mechanical load is above an advantageous power range of the combustion engine. The control system limits the fuel supply of the combustion engine during the peak-load situation so as to restrain the fuel consumption from increasing due to the peak-load situation.
