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.

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...

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...

A nuclear power plant has an overall efficiency of 31% and a power output of 800MW. For one year operating at full capacity, calculate a) the number of joules produced; b) the number of fission events that were required to produce those joules; c) the mass of uranium oxide (UO2) that has been used in fission; and d) the market cost of that uranium oxide if it was all high quality.

For synchronous generator to work at lagging PF and unity PF, which one have more efficiency?...

For synchronous generator to work at lagging PF and unity PF, which one have more efficiency? Why? (Ra is not equal to zero)

Define power. How are sample size and power related? How are effect size and power related?
