Design of electric power quality monitor device based on OMAP-L137

摘要:

提出了基于OMAP-L137的电能质量监测仪的设计方案。在此基础上，介绍了本仪器的软、硬件结构及算法。针对谐波检测中的动态扰动的存在，采用了一种加窗插值修正算法来提高测量准确度；同时通过Delphi编程工具，设计了良好的人机交互界面，并通过实验验证了系统的可靠性与实用性。

Abstract:

A design scheme about electric power quality monitor device based on OMAP-L137 was proposed. According to this, the framework and arithmetic of the device were introduced. Because of the existence of the harmonic disturbance, a scheme of adding windows combined with interpolation arithmetic was used to improve the accuracy of the measure scheme. Meanwhile, a good interface was designed with the programming tool of Delphi. The reliability and practicability were validated through experiments.
