A wind speed sensorless performance monitoring method for a stand-alone wind turbine-generator system using a straight-wing vertical axis wind turbine is developed through a numerical analysis. This performance monitoring is based on the evaluation of the variation in the power output of the wind turbine to that in the cubed rotational speed; this means that a wind speed sensor and estimation of the inflow wind speed are not required. The comparison with the previously-developed method, in which the wind turbine-generator system must be temporarily operated under a lighter load condition and the inflow wind speed must be accurately estimated, reveals that the newly-developed method needs a slightly more advanced deterioration of the wind turbine performance in order to detect it, but can monitor the wind turbine performance more frequently.
