Problems solved by technology

In general, the amount of meteorological data in the power industry is larger, the time interval is denser, and the format is more complex, which requires more means and methods to process, and the quality of the data is uneven. Integration is more difficult
[0005] Although multi-source meteorological data integration has a certain foundation, there are still the following problems: First, affected by the local climate, data integration has a certain regionality, and the meteorological data integration system cannot access power meteorological observation data such as new energy stations.
Secondly, the observation data of the meteorological department and the power meteorological data such as new energy stations have diversified sources and different structures, and further research on multi-source data fusion technology is needed

Embodiment Construction

[0053] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0054] Based on the multi-source meteorological observation data of new energy stations, this method analyzes the distribution characteristics, timing and spatial correlation characteristics of meteorological observation data, and combines the characteristics analysis of regional meteorological elements of new energy stations under different geographical and climatic conditions. Identification, Bayesian discriminant theory, etc. evaluate data applicability, accuracy, reliability, continuity, completeness, availability, objectivity, etc., and delete redundant data, repair bad data, etc., so that data have high credibility. For unstructured and semi-structured meteorological data, image processing, pattern recognition technology, heterogeneous text data integration, text preprocessing and other methods are applied to reali...

Abstract

The invention relates to a multi-source meteorological data integration method and system. The method comprises: collecting weather meteorological data and electric power meteorological data to form original data; unifying the original data format into a preset standard format; and carrying out integrated processing on all meteorological data which are unified into a preset standard format to forma meteorological monitoring data set. The scheme is used for improving the numerical weather forecast precision and realizing the establishment and application of the customized numerical mode of thepower industry.

Description

technical field [0001] The invention belongs to the field of new energy power generation, and in particular relates to a multi-source meteorological data integration method and system. Background technique [0002] At present, all grid-connected new energy stations and transmission lines have built special meteorological monitoring equipment along the way. Combined with the radar, satellite and conventional meteorological observation network of the meteorological department, the meteorological observation data that can serve the operation of the power grid has shown "diverse sources, The typical characteristics of huge volume". However, due to the different formats and structures of these data, unified integration and application have not yet been effectively carried out. Through the research and application of multi-source meteorological observation data integration technology, the degree of integration and fusion of meteorological data can be effectively improved, and the ...
