For the past four years, Advanced Surface Machinery Programs (SEA 03R2) has been developing the Integrated Power System (IPS) to reduce ship acquisition and life cycle costs while still meeting all ship performance requirements. IPS provides electrical power to ship service loads and electric propulsion for a wide range of ship applications including surface combatants, aircraft carriers, amphibious ships, auxiliary ships, sealift and high value commercial ships. IPS consists of an architecture and a family of modules from which affordable and high performance configurations can be developed for the full range of ship applications. Two years ago, the initial IPS concepts were presented at ASNE Day 1994. Since then, much has been learned through the Reduced Scale Advanced Development (RSAD) and Full Scale Advanced Development (FSAD) programs. This paper describes the fundamental IPS architecture, details the evolving “family of modules” and their interface standards, and outlines the “Mass Customization” based design process for achieving customer performance requirements with an affordable IPS configuration.

Abstract-Quality of Service (QOS) is a measure of the ability of the power system to reliably provide loads electrical power with the power continuity required by the loads. QOS recognizes that different loads can tolerate different power interruption durations. This paper reviews QOS concepts as described in IEEE 1662-2008 and IEEE 1709-2010, describes methods for employing QOS in the design of shipboard power systems, and presents modeling and simulation considerations.
