Power plant expansion

No formula will yield what you expect. you have to know your requirement and deput people who are expert in this area.

Something does not jive here. Are you sure you mean KW and not perhaps MW? If your numbers are accurate, this must be a real small factory, as 8KW is not much in the way of power. For comparison, the average house in North America has about 13 to 20KW, and higher, in the way of demand.

My mistake.. you're right.. 5.5 and 2.5 MW...

honest mistake! :)

Turn the ENTIRE factory roof into a solar generator. Sell the excess to the power grid at $0.15 cents per and then use from the grid all you need.

There is no single formula that will provide answers to your requirements...

Power systems design and integration is a course, and after you had taken the course, will require an extensive track record on power systems components, equipment applications and specifications, control and protection systems and similar issues.

System stability study should also be required...

I'm also a little bit irritated by the low power numbers of the generators. 8kW+ is about what my house consumes if the hob, the dishwasher and the washing machine and tumbler are all together working.

I like the idea of putting solar panels onto the roof and feeding the energy into the local grid. This will however very likely never pay back but it is a first step to use the endless solar energy. It might come very handy if energy costs increase further, which is very, very likely.

BTW, did you check for the kW/MW number? We've got a 3GW Generator in our lab but we use this energy only for experiments with not much more than 3 seconds duration. :-)

I am sure that the rating of Generator is MW instead of KW. For future expansion based on plant expansion plan. No special formula.

I'm not really looking for a single formula...

i'm looking for procedures.. or significant formulas i need to know.. in order to start the study..

sorry for the initial mis-info guys.. it's MW not KW.. my bad..

AHA! MW not kW. This turns the whole thing into a bigger project. If we plan projects like this we use less formulas but a so called decision sheet which is done in Excel or any other spreadsheet program. The hard thing of it is to define different scenarios, define different key features to be reached with the project and finally give everything a weighted number of points. The scenario with most points wins. Usually do we need three offers for the key parts (e.g. the generators) and these offers are - if possible - included in the decision sheet too. In all decision we've done so far we always discovered some other solution or combination which had some hidden advantage or disadvantage if we changed the weighting and caused common surprise to all concerned persons. All this together gave more confidence to everyone and it was usually easy to convince the management to e.g. go with a more expensive solution.

The techniques for the decision sheet are absolutely simple. But be warned: the information content of the table is very high :-)

Don't forget to consider local regulatory requirements (and potential future ones) in related areas. Air emissions, water pollution and consumption, fuel costs and availability, etc.

I like the environmental ideas of EnviroMan. Those points should go into the decision spreadsheet too. If you miss exact figures for some of the requested fields for the different scenarios you can fill in your personal assumptions in first place to get at least an - however - subjective idea what's the best solution.

Yes, it's not just about tree-hugging. These are real requirements that can cost real dollars (Euros, pounds, pesos, francs, yen, rubles, etc.) and woe betide anyone who fails to consider ALL of the monetary costs!

Looks like , Disel Generators.

Since they are quite unequal capacity , it is difficult to run parallel wiithout good electronics. If you can not make parallel then you will need separate HT and LT panels with Change over switches. So future generators, should be parlleling types.

Look at all Breakers and there cable sizes and find out any extra capacity is there or not.

But before you embark , look at your 24 Hrs loading. If load factor is low <60% , then look for ways to increase to 80% level by changing some timings. Also use Maximum Demand controller to switch off non essential loads if the loading is near sturated.

Lastly if it is not possible and you have short peak load period of say 2/3 hours, you can go for a Load levelling unit , which comprises of batteries of say required extra load capacity for the peak and a motor generator set. So during peak , Battery takes the additional load. During off peak Battery gets Charged. So you dont have to go for immediate substation expansion.The generator gets the field current from other sets , so that the frequency is easiliy synchronised
