The invention relates to a wind power plant comprehensive evaluation method, in particular to a wind power plant comprehensive evaluation method based on an analytic hierarchy process and a comprehensive distance evaluation method. The wind power plant comprehensive evaluation method includes the following steps that firstly, wind power plant running evaluation indexes are selected; secondly, an evaluation matrix is subjected to index same-direction treatment and nondimensionalization treatment to acquire a standard evaluation matrix; thirdly, an evaluation matrix and index weight vectors are determined based on the analytic hierarchy process; fourthly, the relative proximity corresponding to each wind power plant is worked out according to the comprehensive distance evaluation method, and comprehensive evaluation on wind power plant running conditions is carried out through sorting of the relative proximities. By means of the method, safety running conditions of the wind power plants are fully and objectively evaluated, and evaluation evidence is provided for electric power departments in comprehensive comparison of wind power plant running conditions.
