Wind power field grade yawing dynamic optimization method and system for sector adjusting and control

The invention relates to the technical field of wind power field control, in particular to a wind power field grade yawing dynamic optimization method for sector adjusting and control. The method comprises the steps that onsite monitoring data of each wind power generator are obtained; payload data for expressing the part payload situation of all wind power generators are obtained; aiming at a plurality of pre-divided sectors, based on the onsite monitoring data and the payload data, whether wind power generators are influenced by wake flow of the other wind power generators in the corresponding sectors is judged one sector by one sector; and the wind power generator which is influenced by the wake flow is subjected to yawing optimization control so that the corresponding wind power generator can reach the optimal power and optimal payload under control of a yawing motor. The invention further relates to a wind power field grade yawing dynamic optimization system for sector adjusting and control. According to
