Methods and systems for improving stall controlled wind turbine effective ness by accurately determining wind speed without using an anemometer or oth er independent wind speed measuring device. Wind speed may be determined, am ong other methods, by tracking a mapped TSR model with respect to an operati ng stall controlled wind turbine in a given TSR range; decreasing a Ramp Sta rt RPM value upon reaching a maximum desired power level and by following a mapped RPM into ramp (the control going into RS) for the desired wind speed range; upon reaching a desired RPM level, raising the RPM with power; and/or using periodic unloading of the rotor. The wind speed information may be ut ilized to control wind turbine parameters. |
