The US Navy has been researching integrated electric propulsion systems for many years. The economic advantages of the integrated electric architecture, where power for propulsion as well as ship service are derived from a common set of generators, are well recognized and such systems are used throughout many sectors of the commercial marine industry today. In addition to the economic advantages, there are military benefits to the ship when an Integrated Power System (IPS) architecture is adopted. Those include increased reliability and survivability, reduced signatures and increased upgradeability.
A full scale Land Based Engineering Site (LBES) was constructed at the Advanced Propulsion and Power Generation Test Site (APPGTS) of the Naval Surface Warfare Center, Carderock Division – Ship Systems Engineering Station (NSWCCD-SSES) in Philadelphia, Pa, to demonstrate the system architecture and feasibility of chosen technologies for a warship application. This paper will describe the IPS, test site construction, and test operational experience with a GE LM2500 engine, utilizing a Woodward Governor Company (WGC) MicroNet controller, as the prime mover for the main generator set.
