Title:

CUT-OUT STRATEGY ADAPTIVE ADJUSTMENT METHOD AND APPARATUS

Document Type and Number:

WIPO Patent Application WO/2019/148770

Kind Code:

A1

Abstract:

A cut-out strategy adaptive adjustment method and apparatus, a computer readable storage medium, and a computer. The method comprises: predicting wind resource parameters of a wind turbine at each turbine site by using a wind speed prediction model (S101); predicting a fatigue load and a limit load of the wind turbine by using a load prediction model according to the predicted wind resource parameters and an air density (S102); comparing the predicted fatigue and limit loads with reference loads (S103); and determining a cut-out strategy on the basis of the comparison result, wherein the step of determining the cut-off strategy comprises: determining a cut-out wind speed and an output power.
