摘要
提出了电能质量分析仪用于电压暂降测量的校准检测方法,该方法通过电压暂降自动校准检测系统实现仪表的校准检测。从SEMIF47和IEC61000-4-11规范的设备敏感曲线、典型电压暂降波形、IEEE及IEC关于电压暂降标准定义3方面确定了15种电压暂降标准波形,以此获得被检测仪表Fluke1760的实验测量数据,从测量准确性、暂降参数、电压暂降均方根计算时长、录波功能等方面考察了该仪表的电压暂降测量能力,进而可根据分析结果对被检测仪表进行参数校准。
A method to calibrate and detect power quality analyzer for measuring voltage sag, which implements calibration and detection of the power quality analyzer by automatically calibrating detection system through the measurement of voltage sag, is proposed. Fifteen standard voltage sag waveforms are decided according to the standard sources from three sides, i.e., the instrumental sensitivity curves specified in SEMI F47 and IEC 61000-4-11, typical voltage sag waveforms and the standard definition of voltage sag given by IEEE, and on this basis the experimental measured data of the detected power quality analyzer Fluke 1760 is obtained, then by these data the voltage sag measurement capability of Fluke 1760 is explored in the aspects of measurement accuracy, sag parameters and calculation duration of root mean square （RMS） value of voltage sag as well as recording function, thus the parameters of detected power quality analyzer can be calibrated according to analysis results.
