Capaci of a Generator

100kW, and yes. Is that asap enough?

Sir, our load is 100kw how we can use generator with the capacity of 100kw. i think it must be more than our load.

and what about the countinous running of a generator for long time ( 6 months or more) answer any experienced person please. thanks

Bhatti,

Your question is too vague to come up with a viable answer.

Do some research on the internet. You should be able to find what information is required to come up with the correct size.

Try a Google search, here allow me.

Two 500 KVA generators (one as stand by) should do it!

Right now to be sensible:

• Are there any heavy loads to be started?
• How critical are the loads
• Power factor of the load

There's others factors I can't / don't want to think of at the moment, (I've had a few beers). You know the details of the loading we don't. If the load is critical it needs a standby generator. Heavy starting loads require a generator of X% over the base load, depending on the starting characteristics of the load. Power factor is reflected by a higher running current KVAr as to actual theoretical current KW resulting in a higher O/P required at the generator.

A 100KW generator will not supply a 100KW load.

Talk to the generator manufacturers.

Sir There is a load of two heavy Motors of sullary pumps 55KW each and four three phase motors of 7 KW each with 10 in nos hollogon lights of 1000 Watts.

Waiting reply please. Thanks

Well, (2 x 55kW) + (4 x 7kW) + 1kW is >100kW. Are the big pumps both running at the same time? If so, then the 100kW load figure is too low and a larger generator will be needed.

What about diesel-driven pumps, as an alternative?

You should consider LRC of motors,starting method,whether both starts together etc
