I would like as many equations as you could give me. I am particularly looking for eqautions that deal with any relationship between the Tip Speed Ration (TSR) and Pitch angle of wind turbines. Also I'm looking into converters that are found in wind turbines. If you know any good references or information about them I would greatly appreciate it. In particular, I know that they provide power to the wind turbine during Voltage Dips but I don't know where their power supply comes from. Any enlightenment would be greatly appreciated!
