The invention provides a power optimization method and device for a wind generating set. The power optimization method comprises the steps that before-optimization data of the wind generating set within a preset period of time before the wind generating set is optimized and reference before-optimization data of a corresponding reference wind generating set are acquired; after-optimization data ofthe wind generating set within a second preset period of time after the wind generating set is optimized are acquired; a power corresponding relationship between the generation power of the wind generating set and the generation power of the reference wind generating set is acquired according to the before-optimization data and the reference before-optimization data; the speculated power of the wind generating set and a speculated wind speed are speculated according to the power corresponding relationship, the before-optimization data and the after-optimization data; and the optimization effect of the optimized wind generating set is verified according to the speculated power and the speculated wind speed.
Description
technical field [0001] The present invention relates to an optimization method and device, more specifically, to a power optimization method and device for a wind power generating set. Background technique [0002] As the frequency of wind turbine optimization is getting higher and higher, people pay more and more attention to the verification of the optimization effect of wind turbine optimization. [0003] Usually, when verifying the optimization effect of the optimized wind turbine, the wind speed data before and after the optimization of the wind turbine are obtained first, and then the wind turbine is optimized under standard air density conditions. The wind speed data before and after optimization are processed separately to obtain the power data of the wind turbine before and after optimization under standard air density conditions, and then the wind speed data before the wind turbine is optimized and the corresponding power data are generated A power wind speed curv...
