Abstract
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 () and the network side converter (), 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 () and the network side converter (), based on the criterion of keeping every subsystem operating temperature as far as possible from its corresponding limit.
