Abstract:	Voltage fluctuations caused by the rapid changes of loads in the power system may give rise to noticeable illumination flickers of lighting equipments. Evaluation of voltage fluctuation becomes an important issue for the grid integration of wind energy systems. To provide accurate estimation of grid situations, a calibration test prototype is designed in this paper to assess the capability of commercial flickermeters. In accordance with the latest International Electrotechnical Commission (IEC) standards, the test power signals can be generated and the standard flicker indices can be precisely obtained by designed autoregressive (AR)-model-based synchronization and voltage envelope extraction processes. In this way, the commercial flickermeters can be conveniently calibrated to meet the measurement requirements during the continuous operation of wind turbine.
