A Discrete Matlab–Simulink Flickermeter Model for Power Quality Studies

A discrete model of the IEC 61000-4-15 flickermeter is developed for use with the Matlab-Simulink simulation software package. The discrete model is a faithful reproduction of a flickermeter defined by the IEC Standard; it duplicates the functional blocks described by the standard and operates in the same way as the standardized instrument to assure complete fidelity of results. The model is intended to be used within larger simulations that contain discrete model blocks, either alone or in combination with the Simulink SimPowerSystems blockset, to provide direct quantification of flicker. The model is fully developed, and all model parameters are provided for use with 60-Hz systems. A discrete calibrator is described that duplicates the test waveforms described by the IEC Standard.
