Question 59Electricity & Electronics - Assistant Engineer

The correct answer is A) by the use of amortisseur windings. Amortisseur windings, also known as damper windings, help reduce the hunting phenomenon in synchronous generators operating in parallel. These windings act as a short-circuited winding on the rotor, which creates a damping torque that opposes the oscillations of the rotor. This damping effect helps to stabilize the generator and prevent the rotor from being periodically pulled ahead or behind its normal position. The other options are incorrect because: B) Decreasing governor speed droop would not directly address the hunting issue, as it is related to the generator rotor dynamics, not the governor. C) Direct coupling the generator to the prime mover (e.g., diesel engine) would not solve the hunting problem. D) Increasing governor speed droop would not help reduce hunting and may even exacerbate the issue.
