Abstract: This method makes it possible to regulate the power of an energy conversion installation (100) for converting mechanical energy into electrical energy. The installation (100) comprises a machine (1), an alternator (2), a first converter (41), an electrical cable (3) which links the terminals of the alternator (2) to the first converter (41), a second converter (42), means of measurement (8, 41, 43), a control unit (5), the first converter (41) modulating the frequency and the current of the first electrical signal (S2). The method comprises a first prior step in which the value of a first quantity proportional to a reactive power is implemented in the control unit and a main step in which the control unit (5) determines the drive frequency and the drive current on the basis of an error equal to the difference between the first quantity and a second quantity which is both homogeneous to the first quantity, dependent on the reactive power of the first converter (41) and determined on the basis of a measured value of the current of the first electrical signal (S2).
