Field data processing techniques
The problem of global warming raised up interest to renewable energy. To reduce cost of wind energy is challenge. Before building of wind park such conditions like: average wind speed, direction, time for each wind, probability of icing. Also have to be considered amplitude of wind changes and their amount. This thesis presents Nygårdsfjellet wind turbine park data analysing for determining power loses in yaw system based on amplitude and data amount of wind changes. In thesis obtained experimental dependence between time, amplitude of wind changes and angular speed of nacelle rotation. Power loses in yaw system for each month of 2008 year were calculated and presented graphically.
