英文摘要：

Aiming at the difficulties that the controller parameter of wind turbine are hard to be calculated and adjusted during the process of design and optimization, a linear model of wind turbine suitable for pa- rameter adjustment was proposed through the model linearization of Bladed software, to which the Pl con- troller parameters were adjusted based on the immune genetic algorithm, and subsequently a complete set of adjustment and optimization method for variable-gain PI controller parameters was established via calcu- lation on the parameters of general and variable gain PI controllers according to statistical probability of wind speed in wind farm and identification parameters of Bladed software. Results show that the method proposed is able to adjust and optimize relevant parameters, which may serve as a reference for design and optimization of variable gain PI controller for wind turbines.
