提出了综合利用商用关系型数据库和商用时间序列数据库的集成方案,结合广域监测系统(WAMS)的数据特点,分析了WAMS系统对于数据存储的要求,并对比了两类数据库的特点。这一方案可以充分发挥两种数据库的优点,同时满足WAMS系统数据存储实时性、海量性和安全性的要求,从而为调度中心的各个专业部门(调度、运方、保护)提供统一的集成数据平台,有利于WAMS应用功能的扩展应用。该方案的有效性得到了实际工程应用的验证。
In this paper, the integration scheme of commercial relational database and commercial time series database is proposed. According to the data characteristics of WAMS, the requirements of WAMS for data storage are analyzed and the characteristics of the two kinds of databases are compared. This solution can give full play to the advantages of the two databases and meet the real-time, mass-quality and security requirements of WAMS system data storage so as to provide uniform and integrated data for various specialized departments (dispatching, transporting and protecting) in the dispatch center Platform, is conducive to the expansion of applications WAMS applications. The effectiveness of the program has been verified by practical engineering applications.
