Development of the DSP-based digital flickermeter

In order to develop the IEC standard based flicker meter, analog model of the flicker meter is developed by Matlab according to the functions and design criterion suggested by IEC. After making certain the analog model parameters and the sampling frequency, bilinear transformation is adopted to convert the analog model to digital system. DSP-based digital flicker meter is developed based on the simulation results, and it is proved to be high-precision by simulation and experimental results. It can match the precision requirement of IEC standard. (5 pages)
