Abstract :
In this paper, a variable-speed wind turbine generator system with a vector controlled back-to-back PWM- VSI on the stator side has been modeled, designed and simulated to study its steady state and dynamic behavior. The grid connection control mode of a wind turbine based on a flexible dSPACE digital signal processor system that allows user-friendly code development, monitoring and online tuning is used. The design of an LCL-filter, current controller and DC-link voltage controller are described in detail. The PI- controllers are designed using pole-zero placement technique and the gain of the regulators are found using root locus method.
