This Linear Model will go in for developing controllers to provide trade-off in annual energy production, design life and margins to operating boundaries.Contribution1. Developed state space Matlab model for the wind turbines, which go in for developing the model-based controller. 2. Improved Flex (GE Proprietery software) to account for aerodynamics in the Flex -Simulink linear dynamic model.Impact : Maximum energy capture and fatigue load reduction. Loads Extrapolation : Signal Processing (Fourier) – Matlab The project investigates the root cause analysis for extreme loads experienced by the wind turbines for various wind speeds and turbulence intensity. Extreme loads are analyzed using various statistical tools. This investigation is useful in avoiding over design of wind turbines, saving cost and certification from IEC – “International Electrotechnical Commission”. Contribution1. Developed a Matlab signal analysis tool for identifying outliers in Wind turbine simulation. Impact : Results directly impact the turbine design and certification from IEC. Show less
