Abstract

The invention relates to a wind turbine comprising a rotor (10) having a hub (12) and at least two blades (14) that have respective liquid tanks (34) or that are firmly connected to at least one liquid tank each, an imbalance sensor (30, 52), a control unit (44) for continuously detecting an imbalance of the rotor from the signal of the imbalance sensor, at least one liquid reservoir (42), and a transfer system (36, 38, 40, 46, 48, 50), suitably controlled by the control unit, for transferring liquid between the liquid reservoir or the liquid reservoirs and the liquid tanks when the rotor rotates depending on the detected imbalance to continuously minimize the imbalance of the rotor.
