Abstract: An electromechanical power-split system and a method of operating thereof is provided, with a mechanical drive branch including an internal combustion engine (3), and with an electric drive branch including a first motor-generator block (59) including a first motor-generator (1) and a second motor-generator block (60) including a second motor-generator (2), the first motor-generator (1) is connectable to the internal combustion engine (3) and to the second motor-generator (2). The system includes a planetary gearset (4) with dual planet gears (46) and four input/output members for altering the flow ratio of the mechanical and electric drive branch. Each dual planet gear (46) is connected to the four input/output members, which are a first pair of input/output members formed by a first sun gear (41) and a ring gear (44), and a second pair of input/output members formed by a second sun gear (43) and a planet carrier (45).
