At least to a certain extent, by increasing the field current.
Or
In Real Power Plant they decrease the power factor to increase the voltage.
The generator terminal voltage will increase.
In a series generator, the voltage output is directly affected by the load. As the load increases, the voltage output decreases due to increased voltage drops across the internal resistance of the generator. Conversely, reducing the load will result in an increase in the voltage output.
This question is not understandable. You can use a step up transformer to increase voltage; you can't increase voltage by producing electricity at a lower voltage; this will result in current flow into your generator, not current flow out (similar to operating a generator in the leading mode). Please explain further under "discuss question".
If it is AC, a transformer. If it is DC, a motor generator.
To increase the amount of electric current produced by a generator, you can increase the rotational speed of the generator, increase the strength of the magnetic field within the generator, or increase the number of turns in the generator coils. These methods will result in a higher induced voltage and therefore a higher electric current output.
The whole idea of synchronization is that you DON'T change the voltage (or frequency) from the other generators.
You would have to apply a higher voltage from outside - for example, in the case of DC, connect a battery that provides more voltage, or connect more than one battery in series; or in the case of AC, use a transformer to increase the voltage.
Power is voltage times current. If you want to maintain constant voltage and yet increase power, then current must increase. Its simple math.
Increasing the number of coils on a generator can increase its voltage output. More coils mean more wire loops, which can generate a stronger magnetic field and induce a higher voltage. This can be useful in increasing the power output of the generator.
The terminal voltage of a self-excited shunt generator decreases with an increase in load due to an increase in voltage drop across the internal resistance of the generator. As the load current increases, the drop across the internal resistance also increases, reducing the output voltage available at the terminals. This effect is known as voltage regulation and is a common characteristic of self-excited shunt generators.
Terminal voltage is the voltage between the output terminals of a generator.
You can use a transformer to increase the current. Note that this will also decrease the voltage. The total energy will not increase; it will decrease slightly, due to losses in the transformer.
