Q4- A 480V, 50Hz, 20KVA Y-connected eight-pole synchronous
generator has a per-phase synchronous impedance of 0.15+??1.1 ?.
The total mechanical and stray losses are 1.5kW. The core losses
are neglected. Assume that the magnetization curve of the generator
is linear. If the generator operates at full load at a unity power
factor, calculate the following:
a.The speed of rotation of the generator at full load.
b.The voltage regulation of the generator.
c.The developed torque on the shaft of the generator.
d.The efficiency of the generator at full load.
