<p>The objective of the invention is to provide a more reliable power generation amount estimation method and power generation amount estimation apparatus for a wind farm by improving the accuracy of evaluation of wind speed for wind power generation systems. This method for evaluating the wind speed of a wake from a wind power generator comprises the steps of measuring wind speed upstream of a wind power generator installed on land or sea, measuring the wind speed of the wake from the wind power generator with a wind-speed measurement means installed downstream of the wind power generator, and calculating the wind speed of a first wake from the wind power generator using at least one parameter among wind speed upstream of the wind power generator, radius of a wind turbine rotor of the wind power generator, distance between the wind power generator and the wind-speed measurement means, thrust coefficient of the wind power generator, and wake attenuation coefficient for the wake from the wind power generator. This method is characterized by calculating the wind speed of a second wake from the wind power generator from a correlation between the wind speed of the wake from the wind power generator measured by the wind-speed measurement means and the wind speed of the first wake from the wind power generator calculated using the parameter(s).</p> |
