摘　　要：随着智能电网建设的开展,不断增长的海量数据使得传统的Oracle数据库无法满足当前用电信息采集系统的需要。基于云计算技术设计了一个智能电网的用电信息采集系统,利用数据存储环境实现对采集前置机集群获取的大规模用电信息的高吞吐写入,利用并行ETL实现与传统应用之间数据的可靠共享,在云计算环境中实现复杂查询和分析计算并高效运行。实验表明,该系统相对于传统关系型数据库集群方案,具有明显的性能优势。With the increasing construction of smart grid, the increasing mass data make the traditional Oracle database meet the needs of the electricity consumption information collection system no longer. This paper uses the cloud computing technology to design an electricity consumption information collection system for smart grid. The system enables high throughput writing operation of large scale electricity consumption data from collection cluster by using a cloud-based data storage environment, and facilitates reliable data sharing with traditional applications through parallel ETL. Complex query and computation are executed efficiently in the proposed cloud environment. Experimental results show that the system is obviously better than the traditional relational database cluster in terms of pertbrmance.
