The invention provides a method for determining the corresponding relationship between the wire windage-yaw-pulsation-tension maximum value and the wind speed. The wire tension maximum value in the wire windage-yaw process can be directly calculated according to monitored wind speed data, and circuit security early-warning information is completed. According to the method, through an obtained wirewindage-yaw average tension expression deduced based on the continuity equation and the balance equation, moderate points are extracted from the analytic solution function for polynomial fitting, andaverage tension polynomials directly related to the basic wind speed are obtained. Meanwhile, obtained pulsation-tension root-mean-square values after calculation according to finite elements are fitted with the gaussian function, and a pulsation-tension root-mean-square-value expression is obtained. The average tension and the pulsation tension are mainly considered, and for the convenience of engineering application, the basic wind speed of the fitting function only serves as a variable, the maximum value of the tension in the target-circuit wire windage-yaw process can be directly calculated according to the actually-measured basic wind speed, and fussy iteration solving is not required.
