In Electrical Generation plants, the generation voltage will
be in the range between 11kV and 33kV. Generator designers
wishes to generate the electricity at high voltages as
possible to limit the stator current required to achieve the
desired output. But certain technical and economical
problems will arise which results in designing the generator
for particular voltage and current ratings.
• Low voltage generation for particular power level (say
500MW) requires large size of the stator conductors as huge
currents flow through the stator because of low voltage. (
Any current carrying conductor size is decided by the amount
of current flowing through the conductors). Thereby increase
in the cost and size of the machine takes place.
• On the other hand, increase of the machine voltage
significantly beyond the minimum necessary value results in
more insulation required on the generator stator windings,
thus increasing its size and cost.
Therefore an optimum value of Voltage and Current values are
attained for designing the generator considering the cost
and size factors of the generator.
Example:
660 MW generation plant usually operate at 23.5 kV with line
currents of about 19 000 A at 0.85 power factor.
