In synchronous generator a synchronous dead load (lamp, furnaces etc) has no ____________ hence it has no natural frequency of oscillation.
A. restoring torque.
B. mechanical rotatory system.
C. synchronizing power co efficient.
D. damping torque.
Share your understanding of this question with the correct explanation.
The answer is A. restoring torque.
A synchronous generator is a type of electric generator that produces alternating current (AC) by using a rotating magnetic field. The rotating magnetic field is created by a DC current that is passed through the field windings of the generator. The AC current is produced by the interaction of the rotating magnetic field with the stator windings of the generator.
A synchronous generator can be loaded with a variety of loads, including resistive loads, inductive loads, and capacitive loads. A synchronous dead load is a type of load that does not have any reactive components. This means that the load does not consume or generate any reactive power.
A synchronous dead load does not have any restoring torque. Restoring torque is the torque that is produced by the rotating magnetic field of a synchronous generator. Restoring torque is what keeps the generator running at a constant speed.
Without restoring torque, a synchronous generator will not have a natural frequency of oscillation. This means that the generator will not be able to oscillate around its operating point.
Here are some additional details about synchronous dead loads:
- They do not consume or generate any reactive power.
- They do not have any restoring torque.
- They do not have a natural frequency of oscillation.
Synchronous dead loads are often used in applications where a constant frequency is required. For example, synchronous dead loads are often used in power plants to help regulate the frequency of the power grid.
