高分辨率中国近海风能资源数据库开发设计

Development and Design of a High Resolution China Offshore Wind Energy Resource Database

构建中国近海风能资源数据库可以为中国近海风电场规划、前期选址、风能资源评估提供强有力的数据支持。本文对国家气候中心基于中尺度气象模式所获得的中国近海高时空分辨率的海上风能资源数据做了基本分析和评价,论证了利用该数据作为中国近海风能资源数据库数据源的有效性,给出了中国近海风能资源数据库的设计原则,采用当前主流的Spark技术体系,结合地理信息系统和网络技术,给出了该数据库的详细技术架构,构建了基于地理信息系统的高分辨率中国近海风能资源数据库,并介绍数据库的技术特点以及主要功能。研究结果表明,本数据库数据源可靠、架构清晰合理,可以便捷地实现风能资源数据的检索、查询、统计计算和数据展示及有效存储管理,为开展中国近海风能资源的管理与评价提供了有效的技术平台。

The China offshore wind energy resource database can provide strong support for China offshore wind power plant planning, site selection and early-stage wind energy resource evaluation. In this paper, the data of offshore wind energy resources with high spatial resolution obtained by the National Climate Center are analyzed and evaluated based on the mesoscale meteorological model. The validity of using the data as the source of the database is demonstrated, and the design principle of the database is provided. The detailed technological architecture of the database is described based on the current mainstream Spark technology combined with geographic information system and network technology. China’s offshore wind energy resource database with high resolution is finally constructed based on GIS. The technical characteristics and main functions of the database are introduced in this paper. Results show that the data source of the database is reliable and the technological architecture is clear and reasonable, which can facilitate the search, query, statistical calculation, data display and effective storage management of wind energy resources. The database can serve as an effective technical platform for the management and evaluation of offshore wind energy resources in China.
