Hi everybody
I am a student of electrical engineering, and i am about start writing my Thesis.
The thesis is about monitoring the load on the distribution grid. there has been installed some smart meters at costumers side and along different nodes. the data is collected from those meters in a period of 2 month...So the question is, i have: Current, voltage(3 phase), power, date and so on...what i am asking is:
What calculations should i show ?
what is important to know about them, and why?
if the nominal voltage is 230 volt, what if in some time in a day shows at 220 and some at 232 V?
what kind of diagrams is important to show?
i am using Matlab program, can also use Maple
EXAMPLE:
| SKAB | AFGANG | DATO | Column1 | L1V | L2V | L3V | L1I | L2I | L3I | PL1 | PL2 | PL3 |
| 1 | 1 | 22-01-2013
11:00 | | 227 | 230 | 230 | 74 | 39 | 39 | -16,6 | -8,9 | -8,8 |
and 1 costumer data:
costumer1-1-U-L1;15-2-2013 00:00:00; 231.06 V
costumer1-1-U-L1;15-2-2013 00:10:00; 231.37 V
costumer1-1-U-L1;15-2-2013 00:20:00; 231.34 V
Regards
A confused student
