Abstract:

The wind turbine never maintained the speed as constant, because of shadow effects and wind shear mechanism produced irregularities of speed when the wind turbines are connected to the grid. Also the generation of power contains oscillations because of sags are involved with in the continuous mode of operations. This paper concentrated on the utilization of MW- level wind turbine variable speed from the double fed induction generator identified the presence of sags and their compensations. In order to maintain the compensation purpose here introduced individual pitch control strategy for control the generation of sags at variable speed drive environment conditions. The controller which is organized according to the active power generation from the grid and azimuth angles from the wind turbine. Fuzzy logic controller is provided to achieve the required to achieve the yielded responses from the wind power systems. The simulation model results are tested and verified under the MATLAB/ SIMULINK for the wind turbine models. When we observe the waveforms explains that they contain less damping oscillation from the wind turbine in continuous mode operation also IPC compensate the sags problem effectively from the wind turbines.
