摘要
由于随着电力工业的发展,电力系统的可靠性和电能质量越来越多地受到广泛地关注,同时对电力参数的检测也提出了更高的要求;文章利用DSP控制器的精度高、运算能力强和集成硬件资源丰富等特点,设计了以TMS320LF2407A为核心的双DSP结构的电能质量监测系统;它与单个DSP系统相比,提高了监控系统的可靠性;文中给出了硬件电路设计,同时介绍了采用μC/OS-II实时操作系统和前后台系统相结合的软件设计方案,介绍了C语言和汇编语言混合编程设计的方法,实现了实时系统实时控制的要求。
With the development of electric industry , power system reliability and power quality have been put more and more attention , and more effective monitoring equipments are needed to detect the power parameters. Using DSP＇s advantages of high precision, powerful operation ability, enriched hardware resources, this paper designs power quality monitor system based on dual-DSP of TMS320LF2407A. Compared to single- DSP system, it improves the reliability of the monitor system. The hardware circuit are included. The software combines the advantages of μC/OSⅡ and forward/backward system. The rules of mixed programming with C language and assemble language are provided. It meets the requirement of real time control.
