An electric system of an electromechanical power transmission chain comprises a first capacitive circuit (101), converter equipment (102) between the first capacitive circuit and one or more electric machines, a second capacitive circuit (103), and a direct voltage converter (104) between the first and second capacitive circuits. The electric system comprises a control system (105) for controlling the direct voltage converter in response to changes in first direct voltage (U DC1 ) of the first capacitive circuit and for controlling the converter equipment in response to changes in second direct voltage (U DC2 ) of the second capacitive circuit. The control of the first direct voltage is faster than the control of the second direct voltage so as to keep the first direct voltage on a predetermined voltage range and to allow the second direct voltage to fluctuate in order to respond to peak power needs.
