Large motor to run a water pump - induction or synchronous motor? 4

[Bronzeado]

Hi Folks,

In the first stage of a big water project, it was specified 6,9 kV synchronuos motors (2 to 13 MW) to run the water pumps. These pumps are supplied by 230/6,9 kV transformers fed by a dedicated 230 kV radial power system (150 km) with several susbtations.

Now, there is a doubt about if that choice was correct. So, what kind of motor should be better to run the new water pumps in the second stage, induction or synchronous motor?
Also, which motor nominal voltage should be more adequated?

I wonder if the experts in this forum could give us some tips about that choice, showing the advantages and disadvantages in each case. Thanks!

Thank you Keith for pointing out the error.
I meant 13MW and not 13kW.
Apologies!
