Powering the Future with the Integrated Power System

Abstract

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.

Collaborative Protection and Control Schemes for Shipboard Electrical Systems

“…For the shipboard systems, it is becoming critical that the reconfiguration can seamlessly transfer loads to an alternate source since a small interruption in power to equipment like weapons system may have catastrophic results [1,22,23]. The DC Zonal architecture offer opportunities to achieve this goal.…”

“…DC distribution for SES has many attractive features compared with the conventional AC distribution [1,2]. The goal of this research is to address the challenges associated with DC SES, specifically the challenges associated with the system protection and configuration management.…”

A reference governor-based hierarchical control for failure mode power management of hybrid power systems for all-electric ships

“…The case study parameters are shown in Table 3. Since we are emulating a gas turbine failure, the T w is chosen to be T w = 5min, which corresponds to the warm-up times for shipservice gas turbines [2]. The main purpose of the case study is to illustrate the benefits of the controller in Algorithm 1.…”

“…The demand on the HPS is represented as a hypothetical power profile (Fig. 7) that was chosen based on [2]. The case study parameters are shown in Table 3.…”

“…The shipboard integrated power system (IPS) ( [1], [2]) used in all-electric ship (AES) is a representative example of HPS and provides the motivating application for this work. The main components of a typical DC HPS, as shown in Fig.…”
