Question 69Electricity & Electronics - Assistant Engineer

You are correct, the answer C is the correct response. To equalize the kvars between two AC generators operating in parallel, the generator with the larger lagging kvar value should have its voltage decreased, while the voltage of the other generator should be increased. This will help balance the reactive power (kvar) output between the two generators. The other options are incorrect because: A) Increasing the voltage of the generator with the largest kvar would further increase its reactive power output, worsening the imbalance. B) Adjusting the generator speeds would not directly affect the reactive power balance. D) Decreasing the speed of the generator with the largest kvar would reduce its active power (kW) output, but not necessarily balance the reactive power.
