Abstract

The invention discloses a method for optimizing the type-selecting of a wind power generator set comprehensively in the technical field of wind power generation. The method disclosed by the invention is provided with two stages of preliminary type selecting and type selecting in detail; at the stage of preliminary type selecting, calculating a resource match index and a machine type cost index ofeach machine type to be selected respectively, and determining the selected machine type according to a comprehensive match index; and at the type selecting stage in detail, calculating the network access electric quantity per year of each selected machine type and the total service life cycle cost respectively, and determining a recommended proposal according to the comprehensive value index. The method provided by the invention has the advantages of less input parameters, is simple and convenient to operate, and the like, and is suitable for the type selection work of the wind power generator set in a wind power station engineering design.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a comprehensive optimization type selection method of a wind power generating set. Background technique [0002] Wind turbines are the core equipment in wind farm projects, and their investment accounts for about 74% to 82% of the total investment in the wind farm. In addition to the huge amount of investment, the matching between the unit and the characteristics of wind energy resources, operational reliability, and maintainability have a major impact on the economic benefits of the wind farm's entire life cycle. [0003] In recent years, with the rapid growth of global wind power installed capacity, the wind turbine manufacturing industry has also developed rapidly. With the continuous increase of turbine manufacturing enterprises and the rapid development of research and development level, models with different technical routes and performance parame...
