摘要
针对基于DSP的有源电力滤波器(active power filter,APF)进行谐波补偿的实际需要,提出了基于VB6.0和数据库的电网监控系统。利用VB6.0设计上位机的监控界面,主要包括控制菜单和电网参数图形显示;系统数据库选用ADODC控件进行数据库管理,采用SQL结构化查询语言;监控系统通过CAN工业总线进行数据通信。初步的联合调试表明,此监控系统能对APF进行有效的监控和保护,提高了APF系统的可靠性与自动化水平。
Aiming at the requirements of the DSP-based APF （Active Power Filter,APF for short） for harmonic compen-sation,this paper presents a monitoring system based both on VB6.0 and database. The system makes use of VB6.0 to design the upper monitoring interface,including control menus and graphical display of grid parameters;selects ADODC control for database management, using SQL （Structured Query Language） ;implements data communication via the CAN industrial bus. It is proved that this monitoring system can supervise and protect APF effectively,increasing the reliability and automation level obviously, though preliminary measurements.
