I tested my inverter experimentally and I obtained the THD of the inverter output voltage by using power analyzer YOKOGAWA WT1800 and it gave me a certain value. then i wanted to verify this value by the simulation results. where, i use a matlab simulink as a simulator. i used FFT tools of the powergui to calculate the THD. but it gave me a different value ( greater than the experimental value by a double). i don't know what is the reson for this difference.
Please, if anyone is familiar with calculation of THD tell me what is the solution for this problem?, and how can i compute the THD in simulink to be the same or near from the results of the WT1800 analyzer?.
Thanks,
