v_pan Posted March 6, 2009 Report Share Posted March 6, 2009 hello .... i send from microcontroller via rs232 2 signals (take them from sensors) Volt and Current ..i can plot them and store them.. so far so good..no problem! i can also estimate reactive power S=P + iQ the problem is how i estimate average POWER (real) one idea is to multiply V*I (any sample) then pass to Low Pass Filter at 5Hz and that i receive is real power (sounds simple!) i test it on simulate signals and works great but labview don't recognize my two "signals" as signals! what can i do for this? do you have any idea?
