AbstractThe application and removal of a Large Scale dynamic loads is a transient phenomenon that takes time and its effects ripple through the whole system. Transient, dynamic power demand of large loads will result, as a minimum, in distorting the conventional AC generator line voltages beyond the MIL-STD-704E allowable limits. Furthermore, large scale dynamic loads are likely to cause a power source instability, generator trip off-line and even failure (shaft shearing) for both, AC or DC generators. It is also imperative that the full power will be available for the required duration with no degradation in quality on both load pulse ends (application and removal). There are several sources that interact affecting the performance of the power system: GCU control loop; Generator mechanical and electromagnetic properties and Load nature. The decoupling of large scale dynamic loads from the prime power while stabilizing the power buses poses significant challenges, and needs to be explored.
