A wind power plant where the driving shaft communicates with a synchronous generator ( 3 ) optionally through a gear ( 2 ) and with a transformer, if any, communicating through an AC/DC inverter 7 with an HVDC transmission cable 9 . The synchronous generator ( 3 ) is connected to a magnetic field controller ( 3 ). In response to an output parameter, such as the power generated by the synchronous generator ( 3 ), this magnetic field controller ( 4 ) is adapted to vary the magnetic field in the generator ( 3 ) in response to said output parameter. As a result it is possible to compensate for a possible variation in the output parameter, whereby said output parameter is stabilized. As a result it is possible to compensate for a varying speed of rotation. |
