Power and voltage generated by a wind turbine are more variable than that produced by conventional generators. Therefore, with the increasing penetration of wind energy into the grid, it is very important to simulate precisely the wind turbine/grid interaction to evaluate voltage fluctuation and other power quality aspects. In this paper, the wind turbine(More)
The control of a variable-speed wind turbine below the rated wind speed is achieved by controlling the generator. The main goal is to maximize the wind power capture at variable wind speed which can be achieved by adjusting the turbine speed in such a way that the optimal tip speed ratio &#x03BB;<inf>opt</inf> is maintained. For higher than rated wind(More)
A new modified compact UWB monopole antenna with WiMAX and WLAN band rejection and Bluetooth applications support is presented. Bluetooth (2.45GHz) support is done by adding a resonance arm to the original antenna modified while WiMAX (3.3-3.7GHz) notch is done by adding an inverted C-Slot into the radiating patch and WLAN (5.15-5.8GHz) notch is done by(More)
The use of the doubly fed induction generator (DFIG) in modern variable-speed wind turbines has increased rapidly. According to the new grid code requirements, wind turbines generators must remainconnected to the grid during grid disturbances so crowbar protections systems is being used to protect the DFIG, this paper introduces a comparison between(More)
