Abstract

The invention relates to a system and a method for large-range synchronous real-time meteorological data measurement and wind speed and direction prediction. The system consists of a high-precision acquisition terminal, a wireless transmission device and a data center. A large-range synchronous real-time meteorological data acquisition, analysis and prediction system consisting of a data center, a plurality of data acquisition terminals and wireless transmission systems can be established by using the system and the method. According to the system and the method, a BP (Back Propagation) nerve network model is utilized, wind speed and wind direction of a target node within 5 minutes can be predicted according to present meteorological data of all points of the system; in order to improve the prediction accuracy, the prediction model consists of eight prediction models, that is, daytime in spring, night in spring, daytime in summer, night in summer, daytime in autumn, night in autumn, daytime in winter and night in winter, each model is acquired through a great amount of data samples through nerve network training and learning, and moreover in the application process, the prediction model is continuously improved according to errors between actual measurement data and prediction data.

Description

technical field [0001] The invention relates to a high-precision, long-distance, synchronous real-time wind speed and related meteorological information collection, analysis and prediction system and method based on wind power generation. Background technique [0002] As one of the power generation methods with the most mature technology, large-scale development and commercial development prospects in the development and utilization of renewable energy, wind power generation is due to its advantages in reducing environmental pollution, adjusting energy structure, and solving electricity consumption problems for residents in remote areas. Its outstanding role has attracted more and more attention from various countries and has been widely developed and utilized. [0003] Although wind power generation has the above-mentioned advantages, it also has disadvantages. The active power output of wind farms is intermittent and uncontrollable, and a large number of grid connections ...

AI Technical Summary

Problems solved by technology

[0005] There are still some deficiencies in the existing wind speed measurement devices: 1) The traditional wind speed measurement devices only measure the wind speed of a single wind farm, and have not formed a collection of meteorological data related to all wind farms in the region, wireless data transmission, and wind speed and direction prediction. Measurement, analysis, and prediction systems cannot measure, collect, and predict synchronous real-time wind speed data of all wind farms in a large-scale power grid, and cannot analyze, study, and predict the output power changes of different wind farms in space, which is not conducive to the system to formulate reliable power generation plans and optimal dispatching; 2) The traditional wind speed measurement device does not synchronize the data of other meteorological factors that have potential correlation with wind power output power, and there is a lack of research on related meteorological factors
