The invention relates to a model selection method for power transmission equipment of a wind power field cluster. The model selection method comprises the steps of: acquiring a distribution model of wind power output in recent M years; calculating a high wind speed truncation risk of the power transmission equipment of the wind power field cluster according to the distribution model of wind poweroutput in the recent M years; and acquiring an evaluation index of the power transmission equipment of the wind power field cluster based on the high wind speed truncation risk and power transmissionand transformation loss, and selecting the power transmission equipment of the wind power field cluster according to the evaluation index. The model selection method can improve the economic efficiency of the wind power field cluster.
