Answer / alee xain

If it is a Synchronous generator, then upon loss of
excitation it starts running at leading power factor. In
this case it would act as "Induction Generator", providing
active power to grid but taking reactive power from it.

Answer / shahin

If the generator is running with leading powerfactor , the
generator's generated voltage will increase.....

Ref. Puschein & Loyd book.

Answer / sethar12

Generator will generate active power (compulsory?) and
leading reactive power. Heating effects of magnetic field
will be both on generator rotor and stator. Generator
terminal voltage increases from its rated voltage. Generator
(and grid) tripping may occur if the inductive load demand
from grid suddenly increases and generator AVR is in manual
mode (as is a normal practice).

Answer / anil

alee xain answer is correct

Answer / gi

it will ac as synchonous generator

Answer / deepak

in leading power factor circulating current flow in stator
& stator end ring will damage

Answer / suthan prabhu

If the generator is running with leading powerfactor ,Power
Utilisation is more than the power generation.

Answer / gi

losses decrease,the genterated power(kva) decrease.

Answer / pandi

if generator run at leading power factor means it supply
the reactive power
