摘要
结合虚拟仪器技术和数据库管理技术,开发了基于LabVIEW的电能质量综合监测及故障录波系统。阐述了硬件构成方案和软件编程方法,并指出了该系统实现的关键技术措施。通过软硬件结合,借助于数据采集卡,实时采集电网电压并检测,适用于三相的电能质量在线检测,实现了长期自动运行、实时测量分析、历史数据管理、故障录波等功能。与传统分析仪器相比,不仅具有开发周期短、操作简单、处理能力强、扩展灵活等优点,而且可在采集速度、采集精度、记录容量等方面满足现在电网研究的需要。
Combined with the technologies of virtual instrument and database management, an integrative power quality monitoring and fault recording system is developed based on LabVIEW. The hardware architecture and software programming as well as the key technical measures are expounded. By hardware and software ways, the power system voltage is collected and detected real-timely with data-acquisition card. It realizes the functions of long-term automatic operation, real-time measuring and analysis, historic data management and fault recording, suitable for three-phase power quality online monitoring. Compared with tradi- tional analyzer,it meets the requirements of power system study for sampling speed,precision and recording capacity, with shorter development cycle, simpler operation, stronger processing ability and more flexible expansibility.
