Wind power plant comprehensive evaluation method based on analytic hierarchy process and comprehensive distance evaluation method

Abstract

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.

Description

Technical field [0001] The invention relates to a wind farm comprehensive evaluation method, in particular to a wind farm comprehensive evaluation method based on an analytic hierarchy process and a distance comprehensive evaluation method. Background technique [0002] From the rapid development of wind power generation and the high accident rate of wind farms, the safety and economy of wind energy utilization are very important. The safety of wind energy utilization will not only have a great impact on the economics of grid operation, but also limit the development of wind power generation to a certain extent. At the same time, due to the intermittent nature of wind resources and regional differences in wind energy, it is difficult to compare the comprehensive operating conditions of different wind farms. [0003] The analytic hierarchy process (AHP) was formally proposed by the American operations researcher Thomas Seti (TLSaaty) in the mid-1970s. It is a combination of qualita...
