The synchronous generator or alternator is an electrical machine that converts the mechanical power
from a prime mover into an AC electrical power at a particular voltage and frequency.
The synchronous motor always runs at a constant speed called synchronous speed. A three phase, 8
pole, synchronous Generator is coupled to a diesel engine running at 500 rpm. It supplies an induction
motor which has a full load speed of 1440 rpm. Find the percentage slip and number of poles of the
induction motor

How is the active power regulated in a synchronous generator?

A synchronous generator is delivering 35% of the power that is capable of delivering to an...

A synchronous generator is delivering 35% of the power that is capable of delivering to an infinite bus. If the electrical power of the generator is doubled, determine the maximum value of rotor angle during the swinging of the generator around its new equilibrium position. Draw the corresponding power angle curve.

During a power outage, a homeowner starts a generator that outputs 4,000 W of electrical power. It burns gasoline at a rate of 15 gallons per day. Gasoline has an energy content of 19,800 BTU/lb, a density of 6.07 lb/gal and a carbon content of 86% by mass. 1. What is the generators efficiency at converting gasoline energy to electrical energy? How many pound of CO2 does the generator emit per day?

A 50 Hz synchronous generator is supplying 60% of its maximum power to an infinite bus through a reactive network. Due to a certain fault, the reactance of the network between the generator internal voltage and the infinite bus is increased four times. After the fault is cleared, 80% of maximum power can be transferred Sketch the mechanical power vs. power angle curves, in the same figure, under the different operation conditions, and annotate all the key points on the...

A 2000 V single-phase synchronous generator is being used as a backup generator outside a diagnostic center. When the generator terminals are short-circuited and a field excitation current of 2.5 A is passed, the ammeter between the terminals read 100 A of full load current. If the terminals of the same generator are opened and the voltage across them is measured using a voltmeter, we get the value of 500 V with the same excitation current. The armature resistance is...

USE MATLAB. PROVIDE MATLAB CODE FOR CALCULATIONS AND GRAPHS! A salient-pole synchronous generator with saturated synchronous reactances Xd = 0.78 per unit and Xq = 0.63 per unit is connected to a rated-voltage infinite bus through an external impedance Xbus = 0.09 per unit. a) Assuming the generator to be supplying 0.25 per unit rated real power, add a plot of the per-unit armature current as a function of field excitation as the field current is varied in the range...
