The invention relates to a method for operating a wind power plant having at least one rotor blade, the blade angle of which can be adjusted, wherein the wind power plant is operated with a predefinable reduced energy output set point. The method according to the invention is characterized in that, in order to determine the potential output (Y4), at least one predefinable operating parameter (X1, Y1, X2, Y2, Y3, X4, Y4, Z4, X5, Y5) of the wind power plant is measured and is applied to at least one stored characteristic curve (21, 22, 23, 24, 30-30''', 31-31''', 35, 36) for the reduced energy output set point, wherein, in addition, the actual energy output is determined and the loss in output is formed from the difference between the potential output (Y4) and the actual energy output. |
