基于TDengine的智能电网监控系统数据存储方法研究

Research on data storage method of smart grid monitoring system based on TDengine

随着泛在电力物联网建设,智能电网监控范围和接入设备规模急剧增加,对数据存储提出了更高要求。针对智能电网设备建模需求,介绍了智能电网监控系统中运用关系数据库和TDengine时序数据序在设备建模的设计细节和实现方法,并详细描述了时序数据库接口设计的几个关键问题和实现方法,最后验证了该方法的有效性。该方法已成功应用于多个智能电网变电站集控系统,为历史反演和事故分析提供了有力的数据支撑。

With the construction of the ubiquitous power internet of things,the scope of smart grid monitoring and the scale of access equipment have increased dramatically,placing higher requirements on data storage.For smart grid equipment modeling requirements,the design details and implementation methods of using relational database and TDengine time series database sequence in smart grid monitoring system to model equipment are introduced,and several key issues and implementation methods of time series database interface design are described in detail.Finally,The effectiveness of this method is verified.This method has been successfully applied to multiple smart grid substation centralized control systems,providing powerful data support for historical inversion and accident analysis.
