Abstract

The invention provides a method for correcting mesoscale wind speed data based on ArcGIS, including: selecting a reference point for correcting mesoscale wind speed data; extracting the measured wind speed data and mesoscale wind speed data of the reference point for analysis, and obtaining annual, monthly and hourly data Correction coefficient; use the polynomial fitting method to obtain the initial mathematical model of the corresponding relationship between the measured wind speed and the mesoscale wind speed; use the annual, monthly, and hourly correction coefficients to correct the initial mathematical model to obtain the mesoscale wind speed correction model; extract the correction model in the ArcGIS system The mesoscale wind speed data is processed by integer processing and divided according to the slope; the mesoscale wind speed integer data corresponding to the preset slope partition is selected and corrected using the mesoscale wind speed correction model. The present invention also provides a mesoscale wind speed data correction system using the above correction method. The invention can improve the accuracy and availability of mesoscale wind speed data through correction, and provide accurate basis for reasonable decision-making in wind farm development.

Description

A method and system for revising mesoscale wind speed data based on ArcGIS technical field The present invention relates to the technical field of wind power generation, be specifically related to a kind of mesoscale wind speed data correction based on ArcGIS method and system. Background technique According to the size of space scale and time scale, weather system can be divided into planetary scale weather system, atmospheric scale degree weather system, synoptic-scale weather system, meso-scale weather system and small-scale weather system; mesoscale wind speed belongs to mesoscale weather system The category of weather systems. For the field of early-stage development of wind power projects, most of them currently use mesoscale meteorological data to simulate the generation of mesoscale meteorological data. The wind speed data of the wind farm is taken as the basis for calculating whether to invest in the construction of the wind farm in the early stage. There...
