摘　　要：以国际电工委员会(IEC)推荐的闪变测量原理框图及设计规范为依据,讨论了系统框图中各环节的传递函数,并利用双线性变换法,将各模拟滤波器变换为数字滤波器,研究了电压波动及闪变测量的数字化计算方法。最后利用MATLAB/SIMULINK软件搭建了仿真模型,对电压波动分量、瞬时闪变视感度S(t)及短时间闪变值Pst进行测量。仿真结果符合IEC闪变测量精度要求,为进一步构建电压波动及闪变测量仪提供一定的理论基础。According to the principle diagram and design specifications of flicker measurement recommended by International Electric Commission（IEC）, this paper discusses the transfer functions in every department of the system diagram, converts all of the analog filters into digital filters with bilinear trasformation method, and researches the digital calculation method of voltage fluctuation and flicker measurement. At last, the simulation model is established using the MATLAB/SIMULINK software so that voltage fluctuation component, instantaneous flicker sensation level S（t） and short time flicker value Pst are measured. The results show that the measurement accuracy coincides with IEC requirement. It may provide certain theoretical basis for further constructing voltage fluctuation and flicker-meter.
