Liu Hong-we · Electrical Automation · 2013
In order to manage the data of power quality of different electricity grids safely and conveniently,this paper proposes a monitoring system for power quality based on embedded database.This system adopts a lightweight embedded real-time database SQLite,which has the advantages of zero configuration,strong portability,simplicity and reliability.It overcomes the shortcomings of traditional system based on hardware or file system which has poor portability.The embedded database SQLite satisfies the power quality data processing requirements and provides a powerful technical support for power quality monitoring system.
