Wind resource assessment method and wind resource assessment system

Abstract

The invention relates to a wind resource assessment method and a wind resource assessment system. The wind resource assessment method include: judging whether a format of original input wind measuring data is an NRC (new radiance group) output format of a wind measuring device or not, judging whether the format of the original input wind measuring data is matched with a preset data format or not, taking corresponding actions according to the judging result to obtain various parameters required for assessing wind energy resources; acquiring each assessment factor and corresponding standard assessment information of each assessment factor, and establishing a fuzzy relation matrix and an assessment factor weight matrix according to the assessment factors, the corresponding standard assessment information of each assessment factor and the parameters required for assessing wind energy resources; obtaining a wind resource grade assessment result via fuzzy variation according to the fuzzy relation matrix and the assessment factor weight matrix. Since the wind resource assessment method does not direct at a specific data format, convenience of the wind resource assessment is improved. Since the wind resource grade is assessed according to the principle of fuzzy mathematics, rationality and scientificity of the wind resource grading are improved.

Description

technical field [0001] The invention relates to the field of wind data monitoring of wind farms, in particular to a wind resource assessment method and a wind resource assessment system. Background technique [0002] Wind power uses natural wind as the driving force, and the output power of wind farms depends to a large extent on the characteristics of wind energy resources in the wind power development area. Real-time assessment of the distribution of wind resources in the wind power planning area, a comprehensive understanding of the distribution and characteristics of wind energy resources, mastering the characteristics of wind energy, and The planning, construction and operation of the power grid are of great significance. [0003] Wind farm wind data analysis, verification, and wind energy resource assessment are important basic tasks in the process of wind farm development and design, especially the quality inspection of massive wind data often determines whether the w...

Problems solved by technology

However, due to the different settings of the observation instruments and the large changes in climate and wind conditions in various places, there are great differences in the data format of wind measurement data, which greatly increases the complexity of wind energy resource assessment. At the same time, the general wind resource assessment system is only Simple classification of wind resource grades is carried out according to the relevant norms of wind resource assessment, without fully considering the actual situation of the wind measurement site, so that the simple division of wind resource grades based on a single index cannot scientifically and reasonably reflect the actual local conditions
