If the frequency of Generator 1 were to be maintained constant regardless of its load, if Generator 1 were made infinitely stiff, its frequency droop under load is eliminated, and... Read more
The ac generator voltage is controlled by the field current and the speed, but the frequency is controlled only by the speed. Since the generator power ultimately comes from the pr... Read more
When the load torque rises, the automatic speed-regulating governor increases the fuel input to maintain the speed. However, it does not fully compensate for the load increase, and... Read more
