A digital implementation of IEC 61000-4-15 flickermeter

This paper presents a digital implementation of a DSP-based digital IEC 61000-4-15 flickermeter. According to the functions and design criteria suggested by IEC, a digital model of the flickermeter is developed and simulated by using Matlab and Code Composer Studio. Then, the developed flickermeter function is applied to perform a series of tests based on IEC Standard 61000-4-15 test procedures to validate its effectiveness. Test results based on the proposed method show that the accuracy meets the requirements of IEC standard.
