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
If the generator load is suddenly increased in one step from P1 to P2, and the mechanical input from the prime mover is also changed fromP1 to P2 to match with the load, the genera... Read more
The maximum power limit Pmax at δ = 90° for the cylindrical rotoris called the steady-state stability limit. Any swing in δ beyond 90° may cause the rotor to lose synchronism and i... Read more
The performance analysis of a 3-phase machine is always conducted on a per-phase basis since three phases are identical except the 120° phase difference. If the ship generator is s... Read more
The performance of a 3-phase generator at the terminals is based on the 3-phase power fundamentals. The generator typically supplies power to more than one load, some of which may... Read more
Hybrid is a new technology, mostly in early development. In recent years, there’s been a significant increase in battery technology and innovation, particularly in the lithium-type... Read more
Electrical installations are present in any ship, from powering of communication and navigation equipment, alarm and monitoring system, running of motors for pumps, fans or winches... Read more
