Introduction:

The three-phase wall outlet is connected through a series of light bulbs inside the light box with switches. Different loads will be applied with different power factors. The current and voltage will be measured at each load. In this experiment, we are going to synchronize the synchronous generator to the system (DWP) and observe its behavior.

Theory:

Using the DC Shunt and synchronous generator the synchronization of the machines is accomplished by matching the speed of the machine and the frequency, to the system while applying a load or without a load.

The light box with lamps the generator is synchronized with a load. Increasing the speed will cause the lights to flash at a resonant frequency that is related to the system and generator frequency. This frequency is the difference between both frequencies. When the voltage is higher at the generator then the wall outlet the lamps will light up, however when vice versa the light bulbs will be darker. When the light bulbs are shut off at that instant the system and generator will be in synch with one another.

To test this the circuit will be tested at different loads and the voltage and current will be measured at these different loads.

Results and Calculations:

For the synchronous generator:

A) Increasing the speed will cause the lights to flash at a resonant frequency that is related to the system and generator frequency

B) When the voltage is higher at the generator then the wall outlet the lamps will light up, however when vice versa the light bulbs will be darker. When the light bulbs are shut off at that instant the system and generator will be in synch with one another.

Similarly, the full load at each load type showed the same results as the no load voltage regulations except the magnitudes were much larger.

Conclusion:

This experiment showed how a synchronous generator can be synchronized with another machine. Also, it can be shown that by applying a load the same rules of voltage regulation apply at unlike power factors. Moreover, synchronous generators verify to have several applications that can be used to increase efficiency within power machines. This experiment gave a great kind on the abstract applications discussed in lecture; showing that the theoretical and measured are the same.
