Embodiment Construction

[0029]The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0030]Participatefigure 1 As shown, this embodiment provides a method for correcting the representative year of offshore wind tower data based on multiple reference stations, including the following steps:

[0031]Step one, data collection. Obtain wind speed data and wind direction data at the height of a single layer of an offshore wind measuring tower. The wind speed and wind direction data are 10-minute wind speed and wind direction data, with a time length of at least 1 year; acquiring data within a 100-km radius of the offshore wind tower Wind speed data and wind direction data of a single-level height of a reference station, where the wind speed and wind direction data are wind speed and wind direction data one hour...

Abstract

The invention relates to an offshore anemometer tower data representative year correction method based on multiple reference stations. The method comprises the steps of data acquisition, data processing, empirical orthogonal function decomposition, regression equation establishment, error checking and representative year correction completion. According to the method, the problem that the correction result of the representative year of the offshore anemometer tower data has a large error can be solved. The method has universality, is suitable for reference stations and data of various sources,and is suitable for offshore anemometer towers and data of offshore and open seas with various offshore distances.

Description

Technical field[0001]The invention belongs to the technical field of wind power generation calculation, and in particular relates to a method for correcting the representative year of offshore wind tower data based on multiple reference stations.Background technique[0002]In recent years, my country's marine wind energy industry has developed rapidly. Researching and understanding the status of marine wind energy resources is of great value to the site selection and planning of offshore wind farms. The usual method is to collect offshore wind tower data to analyze and evaluate wind energy resources. However, since the data time of offshore wind measurement towers is generally only 1-2 years, and the design operation period of offshore wind farms is generally 25 years, it is necessary to collect long-term data from surrounding reference stations to represent the data of offshore wind measurement towers. Corrected.[0003]There are many sources of reference stations that can be selected ...
