摘要
本文简述了电网电压闪变的测试方法和仪器结构，并以电压波动的数学模型为基础，对三种波动信号检出方案的检测原理和特点进行了理论分析和比较，最后提出了一种改进方案。
The detection of fluctuation signal in power supply voltage is the key to the measurement of voltage flicker,the measurement of voltage flicker is briefly described in the paper.Based on the mathematical model of voltage fluctuation,the theoretic analysis and comparison on the principle and feature of three detecting schemes(halfcycle rms circuit,squaring demodulator,fullwave rectifier)is carried out.Finally,an advanced scheme is proposed.
