Wind deflection calculation correction method and device taking Tibet fluctuating wind characteristics into consideration and medium

The invention discloses a wind deflection calculation correction method and device considering Tibet fluctuating wind characteristics and a medium, and belongs to the technical field of overhead transmission line wind deflection calculation, and the method comprises the steps: obtaining a downwind wind speed through the analysis of the actual measurement data of a wind measurement point in the Tibet region, and carrying out the empirical mode decomposition of the downwind wind speed, decomposing the wind speed into the sum of a time-varying average wind speed and a stable fluctuating wind speed; the selected samples are extracted to serve as effective data, the effective data are fitted through the Monin coordinates of the Davenport spectrum, and a Tibet fitting wind spectrum can be obtained; respectively calculating wind deflection angles under different working conditions by using a standard method and a fitting wind spectrum, and further correcting pulsation reduction coefficients under different working c
