| Abstract: | Along with the rapid development of wind power, wind power integration brings power quality problems including voltage flicker that can＇t be ignored. Power quality disturbance detection is the basis and premise of dealing with the power quality problems effectively. First, Ihe paper analyzes the mechanism of the voltage flicker caused by tile wind power integration, and establishes IEC digital flicker instrument model. Secondly, according to the characteristics of the vohage flicker, this paper can＇ies out some improvements in the IEC digital flicker inslrument model. Finally, the model is validated against simulations using MATLAB/SIMULINK platform. |
