基于VB和MSComm的APF监控系统设计

针对电力系统中谐波检测实时性、准确性要求较高的特点,在设计并实现了基于DSP的有源电力滤波器（Active Power Filter,简称APF）的基础上,为了增强人机交互的智能性,开发了基于VB6.0的上位机APF监控系统。主要介绍了硬件系统结构及软件功能,并详细阐述了基于VB6.0程序设计语言和MSComm控件的上位机监控系统的设计,包括串口通信、数据库管理、动态图形显示、历史数据查询等功能模块。系统实际运行验证了VB6.0用于电力系统控制软件设计与开发的可行性和有效性。

Design of APF Monitoring System Based on VB and MSComm

Aiming at the requirements of real-time and accurate detection in power system,and in order to improve the intelligence of HCI（human-computer interaction）,monitoring system is developed based on VB6.0 and active power filter which is designed and implemented based on DSP.The system of hardware structure and software functions are introduced,and the design of upper computer control system based on VB6.0 and MSComm,has been described in details.Several key methods and technologies are discussed,including serial communication,database management,dynamic graph display,historic data querying etc.
