Weekly Electricity Generation

09/19/2011 6:15 AM

Dear all,

I have this simple question. Sometimes my boss is away and I have to prepare the weekly report for the bigger boss. It is about how much electricity generation in a week by our turbine. Initially I assumed it is an average of total electricity we generated in a week. When I compared with the previous report prepared by my boss, it is different. Can anyone tell if there is a formula to get the right answer so that I don't need to ask him? Thanks.

Is there a meter on the output?

What do you mean by average?

If you are taking the daily output, adding it up over a week and dividing by 7, this will be the average daily output for a week, but not the true total.

To get the total for a week, just add up the daily numbers.

How different is it? The reports shouldn't be the same every week. Wouldn't they fluctuate with demand?

There's also a possibility that you figured it right, and your boss has been doing it wrong. This is something that happens very often.

Finally, if you haven't filled out these reports before, just ask them to walk you through a previous report so you can be sure that you're following proper procedure. There shouldn't be any embarrassment in that.

Different in what way? What does the previous report say? If there is a meter (a la #1, and I don't see how you can do your report without one) what does it read - kWh, kVAh?

Well in my apprenticeship i use to give daily consumption of the plant,for a week it is total addition. Usually summary of KWhr,KVAR,KVA,MD1,MD2,PF etc. It should be entirely different for a generating station.

Please describe your instrumentation.

Cumulative kwh or kvah would make this the easiest, but even "snapshots" of instantaneous kw or kva could allow for decent estimating if they are frequent enough. Fuel consumption could also give a hint, but less accurate.
