The difference between an idle turbogenerator and a no-load turbogenerator lies in the presence or absence of a load.
Idling of the hydrogenerator means that the hydrogenerator is operating without load, that is, the generator rotor rotates but does not produce electrical energy. In this case, the generator speed will be very high, but the power output will be zero. No load means the hydrogenerator is operating with a load, but the power of the load is very low, close to zero. In this case, the generator speed will be reduced, but the power output will still be present. At no load, the output voltage and current of the generator will fluctuate to a certain extent, but it will not affect the normal operation of the generator.
I=S/1.73/U=SQR(P^2+Q^2) /1.73/U
If the nominal voltage of the generator U=6.3KV
< p>The active output is 1000 KW and the reactive power is 0: I==SQR(1000^2+0^2) /1.73/6.3=91AWhen 1000 KW and the reactive power is 1000 Kvar, the generator output current: I==SQR(1000^ 2+1000^2) /1.73/6.3=130A
