Part II(30 points): Suppose that the field current of the
generator in the previous problem is fixed at a value of 5 A.
above is set to a value of 5 A.
(a) What will be the voltage at the terminals of the generator if
it is connected to a load
Delta-connected load with an impedance of 24 ∠ 25° V?
(b) What is the efficiency of the generator under these
conditions?
c) Now suppose another Delta-connected load identical to the
previous one is connected in
parallel with the first one.
d) What is the new terminal voltage after the load is
connected?
e) What must be done to return the terminal voltage to its original
value?
Suppose that the generator field current of the previous problem
(Part I) is adjusted to achieve the rated voltage (13.1)?
to achieve the nominal voltage (13.8 V) under full load
conditions.
f) What is the voltage regulation of the generator if it is loaded
at rated kVA with
loads with a PF of 0.9 in lagging?
g) What is the voltage regulation of the generator if it is loaded
with rated kVA with loads with a unit PF?
loads with a unit PF?
