why the capacity of power plant is given in MW though the
generators are rated in MVA?

Answer Posted / lalit

if we talk about the generator then we have to classify the
active power as well as reactive power i.e. V*I because the
reactive power is also used in generator for the excitation
purpose( for flux production). hence its rated as MVA in
other hand, for power transmission only active power is used
i.e. VICos theeta. hence its rated as Mw.

I have made a 3 phase thyristor full bridge rectifier. But at the moment it is working only for the half bridge operation. Both the half bridges are on operation separately but when i put it into full bridge operation the oscilloscope output is zero. I rechecked that the pulses are correct for each thyristor. what could be the possible reason for this?
