The generator's voltage regulator will sense the fluctuation. If the voltage goes low more current will be applied to the armature to compensate. If the voltage goes high less current will be applied to the armature to compensate.
What can usually happen is the permanent magnets in the generator will become energized, and like static shocks, will store energy in them.
A shunt generator is a type of DC generator that does not use a permanent magnet. Reducing the speed of the generator will reduce the output, but not the load the generator requires because the currents in the parallel branches are independent.
What you need to define is the statement "utility- sized electrical generator". It depends on what the generators output is used for as to the way it is internally wired. In some configurations there is no neutral to ground as in a Delta configuration.If the generator is configured for a Wye output and the neutral centre tap is not grounded there will be a floating voltage between the generator and the utility system ground. It is for this reason that the generator's neutral point is grounded to bring the floating voltage down to zero volts to ground.
They will run with different reactive power output, i.e. reactive load won't be equally shared between units.
When the excitation system of a synchronous generator is removed while it is on load, the generator will lose its ability to maintain voltage regulation. This can lead to a drop in terminal voltage, resulting in the generator being unable to supply the required reactive power to the load. Consequently, the generator may operate in an unstable condition, potentially leading to a loss of synchronism and the risk of overheating or damage to the machine. In extreme cases, it could result in a complete system failure or blackout.
What is going to happen when you repeat this experiment on self D.C generator?
this case called (reverse power ) and happen when there is a phase difference between parallel generators and results in passing a circuilating currents from the higher voltage one to the other which result that one to act as a motor
If the rotation is reversed in DC generator the permanent magnetism already occurred for voltage build up process may demagnetize. this will causes no emf induce at starting time.The reversal of rotation is not affect externally excited generators
Tides happen with predictable regularity.
You will get double the voltage.
Voltage Fighter Gowcaizer happened in 1995.
it would get a lot of voltage
