Generator Capacity and Transformer Load

10/23/2009 1:38 AM

Hi,

Good day!

This is regarding the mini hydro power plant

1. What would be the problem if i have to francis turbine connected parallel and it produces only 1100kVA per turbine and it supply to transformer load of 2500kVA and other load of 100kVA?

2. Does the francis turbine with connected generator will be overheated?

3. If theres a problem how to resolve it?

Thanks and regards,

Philip

Re: Capacity of Generator enough for the transformer load?

Generator generates KVA-Limited by Turbine KW- absorbed by load KW - limited by transformer KVA.

Check with the powerfactors and see whether the turbine can provide or not.

If it can, control the pf, and proceed.

If it can not, the turbine will trip (if it has the safety mech in place) else it will slow down, if the system is still stable at lower frequency.

Solution? - Load-shedding.
