estimate Power


Recommended Posts

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


labview don't recognize my two "signals" as signals!

what can i do for this?

do you have any idea?
