Hi to everybody!
I'm trying to calculate active and reactive power starts from current and voltage waveforms.
To do that i've prepared a simulink model and a matlab script, i'll attached to this post.
With simulink is really easy to obtain datas I'm looking for, but it's just a model. My goal is to write analytic formula to do that and after implement into a FPGA for a real calculation in AC/DC application.
Theory said that :
with t2-t1=period T.
So in my code I've multiplie voltage vector for current vector and integrated it during 1 period. The result is not god, but I've no idea why.
Maybe use trapz as integral is not the best way?
Could you help me?
