A method for controlling a wind turbine based on sectors, comprising: acquiring, for each of a plurality of wind speed ranges, a wind resource parameter of each of original sectors of the wind turbine, wherein all of the original sectors cover a total of 360 degrees around the wind turbine; reconstructing the original sectors, based on the acquired wind resource parameter; performing an optimization based on sectors acquired after reconstructing, wherein the optimization is for a power generation amount of the wind turbine being maximum; and controlling the wind turbine based on a result of the optimization, characterized by reconstructing the original sectors based on the acquired wind resource parameter comprises: dividing, with an interval of a predetermined degree, each of the original sectors to form a plurality of first sectors; acquiring a wind resource parameter of each of the plurality of first sectors, based on the wind resource parameter of each of the original sectors of the wind turbine; calculating a comprehensive turbulent intensity of each of the plurality of first sectors, respectively for each of the plurality of wind speed ranges, based on the wind resource parameter of each of the plurality of first sectors and a wake-flow effect of the wind turbine; and performing sector reconstruction to form a plurality of second sectors, and acquiring a wind resource parameter of each of the plurality of second sectors and a comprehensive turbulent intensity of each of the plurality of second sectors, based on the comprehensive turbulent intensity of each of the plurality of first sectors, wherein the plurality of second sectors serves as the sectors acquired after reconstructing. acquiring, for each of a plurality of wind speed ranges, a wind resource parameter of each of original sectors of the wind turbine, wherein all of the original sectors cover a total of 360 degrees around the wind turbine; reconstructing the original sectors, based on the acquired wind resource parameter; performing an optimization based on sectors acquired after reconstructing, wherein the optimization is for a power generation amount of the wind turbine being maximum; and controlling the wind turbine based on a result of the optimization, characterized by reconstructing the original sectors based on the acquired wind resource parameter comprises: dividing, with an interval of a predetermined degree, each of the original sectors to form a plurality of first sectors; acquiring a wind resource parameter of each of the plurality of first sectors, based on the wind resource parameter of each of the original sectors of the wind turbine; calculating a comprehensive turbulent intensity of each of the plurality of first sectors, respectively for each of the plurality of wind speed ranges, based on the wind resource parameter of each of the plurality of first sectors and a wake-flow effect of the wind turbine; and performing sector reconstruction to form a plurality of second sectors, and acquiring a wind resource parameter of each of the plurality of second sectors and a comprehensive turbulent intensity of each of the plurality of second sectors, based on the comprehensive turbulent intensity of each of the plurality of first sectors, wherein the plurality of second sectors serves as the sectors acquired after reconstructing.
