摘要
电压闪变是电能质量问题的一个重要指标,它与供电网中缓慢(0.5～30Hz)重复的电压波动有关。本文采用虚拟仪器技术开发的电能质量在线监测系统,通过电压采样值获得闪变视感度水平和其它严重度参数。实验结果证明所开发的闪变测量功能模块性能符合最新的闪变仪测量标准。
The voltage flicker is one of the indices of power quality ,which relates to slow and repetitive fluctuations (0.5～30Hz) of the voltage RMS values of the electricity supply networks. Based on the vitual instrument, this paper presents an online monitoring system of power quality. Through sampling the voltage, this instrument furnishes the instantaneous flicker level and other severity coefficients. Results of experiment and actual data prove that performances of the developed flicker measurement module are satisfied the latest standard specifications.
