METHOD AND SYSTEM FOR OPTIMIZING CUT-IN/CUT-OUT WIND SPEED OF WIND TURBINE UNIT, DEVICE, AND MEDIUM

Document Type and Number:

WIPO Patent Application WO/2023/020524

Kind Code:

A1

Abstract:

A method and system for optimizing a cut-in/cut-out wind speed of a wind turbine unit, a device, and a medium. The method comprises: governing and analyzing big operation data of the wind turbine unit, and establishing a wind turbine unit power generation capacity power curve function; obtaining a wind speed distribution function model; calculating a unit annual power generation capacity according to the wind speed distribution function model and the wind turbine unit power generation capacity power curve function; counting actual operation state big data of the unit at a certain cut-in wind speed and a certain cut-out wind speed, and calculating, by operating actual state big data, a relationship function of the cut-in/cut-out wind speed and a fatigue load borne by the unit and a main component; obtaining a cut-in/cut-out wind speed meeting requirements by taking the cut-in wind speed and the cut-out wind speed as independent variables and taking a required unit power generation capacity and a fatigue impact load as objectives; or converting the two objectives into a single objective function for obtaining the required power generation capacity to find an optimal solution by taking the required unit power generation capacity as an objective and taking a constraint preference that a fatigue damage value is less than a design value.
