Wind power plant power transmission line conductor type selection method

The invention relates to the field of wind power plant wire selection, and provides a wind power plant power transmission line wire selection method comprising the following steps: obtaining annual power data of a built wind power plant in a set area; based on the annual power data, the annual actual maximum load loss hour number and the maximum load utilization hour number of the wind power plant are determined; determining an actual loss rate and an actual utilization rate based on the maximum load loss hour number and the maximum load utilization hour number; based on the actual loss rate, the actual utilization rate and the alternating current load expression, determining an average value ratio and a peak-valley difference ratio; based on the average value ratio and the peak-valley difference ratio, determining the number of loss hours of the to-be-built wind power plant in the set region; and determining the alternative wire cross-sectional area of the power transmission line of the to-be-built wind powe
