Control system and method for a wind turbine generator, such wind turbine being a variable speed turbine and having a doubly fed induction generator, said control system comprising means for determining the operating temperature of the different subsystems, having the means for dividing the generation of reactive power, both inductive and capacitive, between the stator (3) and the network side converter (6), based on the criterion of keeping every subsystem operating temperature as far away as possible from its corresponding limit, the method comprising the following steps: determine the electrical elements temperature; calculate the closeness of those temperatures to each element corresponding limit temperature; and distribute the reactive power production between the stator (3) and the network side converter (6), based on the criterion of keeping every subsystem operating temperature as far as possible from its corresponding limit.
Control system for a wind turbine, such wind turbine being a variable speed turbine provided with a doubly fed induction generator having a stator and a rotor, the control system comprising:
Control method for a variable speed wind turbine, provided with a doubly fed induction generator having a rotor and a stator, and a converter including a rotor side converter connected to the generator rotor, and a network side converter adapted to be connected to power distribution network, wherein said control method is carried out cyclically and comprises the following steps:
