Voltage fluctuation and flicker is an important indicator of power quality, and accurate measurement of it is important. In this paper, the current internationally accepted method of measuring flicker-IEC flicker measurement method is theoretically analyzed in depth. The transfer functions of various sectors of flicker measurement are given. The MATLAB simulation model of IEC flicker meter is built. Simulation analysis verifies the correctness of the transfer function of various sectors. This paper provides a good reference model for developing the flicker meter consistent with IEC standards, and it has some practical value.
