24-houre power profile

[gfvjhvbvb]

Hi guys

 my senior project regarding Online Power Quality Monitoring using LabVIEW

i have done my project

but i want to take the power value every  1 min  and after 15 min will take the average power value and make it as a ponit in a graph power vs time

start 00:00 and next point 00:15  and so one to 24 hour and save it with its date

how can i do this by using what ?!!

i am waiting for your helping  

thank you

Since this is a school project, we (and you instructor) expect you to do the work.

What have you tried?  What did not work about it?

How is the data formatted in your project? Do you also need to save the original data or only the averages?

thank you sir

i have finished to show the current and voltage and power factor and power in front panel in labview

i have the power value which is change when change the value of current or voltage

P= 3 I V cos@

what i need now to enter the power value to something that create  its profile

XY graph

Y is power value which is the average power value during 15 min

x is the really time or current time 12:00 and 12:15 and so until 24 hours and after 24 hours the labview save this graph with its data

i hope its clear for you now

actullay my project done 90% but still the 24-h power profile i sticked on it

i need the method which block i need

any idea

thank you

It is very difficult to tell what you are doing from a verbal description.  Please post your code with some typical data saved as default.

Wild guess: Are you accumulating data in an array or do you just have one point available at any time?

Look at the Timing Palette. The Elapsed Time function seems to be exactly what you need for both questions.
