摘要

本工作旨在提出一种方法，将现有的电能质量测量数字仪器，即STDAQEE(电能质量诊断和分析系统)，用于获得符合UIE/IEC标准的电压闪变监测能力。采用了建立在数字信号处理和控制理论基础上的时域数字滤波技术。采用IEC制表电压波动信号和随机电压波动信号对样机进行了测试和验证。在最后一种情况下，比较了实验实验室设备和计算模型(MatLab程序)的闪变表响应。结果足以支持该方法，并为改进所建议的设备提供有用的信息。

A proposal for UIE/IEC flicker measurement using digital filters: equipment prototype and validation

This work aims at proposing a methodology to appropriate an existing digital instrument for power quality measurement, namely STDAQEE (power quality diagnostic and analysis system), so as to obtain voltage flicker monitoring capability in accordance with the UIE/IEC standards. Digital filtering technique in time domain is used, which is properly established on digital signal processing and control theories. IEC tabulated voltage fluctuation signals and also a random voltage fluctuation are used to test and validate the prototype. In this last case, flickermeter response from experimental laboratory facility and from a computational model (MatLab program) are compared. The results are good enough to support the methodology and provide useful information to improve the proposed equipment.
