Abstract

The invention relates to a multilayer wind direction and wind speed probability distribution calculation method for tower wind measurement, and belongs to the field of environmental wind field analysis. In order to obtain a multi-layer wind direction and wind speed distribution rule, by taking three-layer wind measurement data of 10 meters, 50 meters and 90 meters of an anemometer tower as an example, a wind direction is fitted by using mixed von mises distribution, a wind speed is fitted by using gamma distribution, and then a layer-by-layer wind direction and wind speed joint probability is obtained according to wind direction and wind speed correlation. Finally, a multilayer wind direction and wind speed probability distribution model of the anemometer tower is established through matpllolib three-dimensional drawing. According to the method, the multilayer wind distribution rule can be scientifically known, the method is suitable for wind energy resource evaluation and engineering structure design, and a foundation can be provided for shallow wind forecast.

Description

technical field [0001] The invention belongs to the field of environmental wind field analysis, and in particular relates to a multi-layer wind direction and wind speed probability distribution calculation method for tower wind measurement. Background technique [0002] In engineering applications and meteorological support, the evaluation and analysis based on long-term wind field data is more critical. The current wind direction and speed analysis of multi-layer wind fields is scattered, either analyzing a single layer, or only analyzing a single element of wind speed or wind direction. The probability distribution of wind direction and speed in multi-layer wind farms is rarely involved. This paper proposes a calculation method for the probability distribution of wind direction and speed in multi-layer wind measurement, which can solve this problem. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the...
