This paper presents a design of pitch controller using Genetic Algorithm (GA) for variable speed wind turbine Doubly Fed Induction Generator (DFIG) . The proposed genetic pitch controller is used to get the proper pitch angle for limiting the mechanical power when the wind speed is greater than the rated wind speed. DFIG is a wound-rotor induction generator where the stator terminals of DFIG ar...

Extraction of maximum energy from wind and transferring it to the grid with high efficiency are challenging problems. To this end, this study proposes a smart pitch controller for a wind turbine-doubly fed induction generator system using a Differential Evolution (DE) based adaptive neural network. The nominal weights for the back-propagation neural network controller are obtained from input-ou...

As one of the most promising Distributed Generation (DG) sources, wind power technology has been widely developed in recent years. Doubly fed induction generator (DFIG) is currently employed as one of the most common topologies for wind turbine generators (WTGs). This generator operates as a synchronous/asynchronous hybrid generators. Therefore, it is necessary to power engineers find understan...

Local renewable resources such as wind and solar are often available in remote locations. Wind farms consist of many individual wind turbines which are connected to the electric power transm­iss­i­o­n ne­tw­o­r­k­. A wind farm can use the wind resources from a certain area efficiently. Double-fed induction generator (DFIG) is a gene­rating principle widely used in wind turbine (WT). DFIG are ab...

Variable speed operation of a wind turbine generator improves its energy capturing capability. Up to the present, the machines employed have been induction machines, conventional synchronous machines or DC machines. The major drawback of these machines is that a complicated arrangement of slip rings or commutators with brushes, and a full-rating power converter are required. Reliability and cos...
