Integrated Power Systems (IPS)
Abstract
This project supports the development and transition of Naval Power and Energy Systems including power generation, power conversion, power distribution, energy storage, power utilization and automation and control functions for fully integrated electric propulsion (such as T-AKE -1 class or DDG 1000 class), hybrid electric propulsion (such as LHD 8 and LHA(R) class), as well as legacy mechanical propulsion ships (such as DDG 51 class). This project supports optimized integration of naval warship power and energy systems to support Directed Energy (DE) and other high powered mission systems, ship power quality requirements including frequency and voltage control for AC systems, Directed Energy (DE) and other high powered mission systems, appropriate component and system controls, integration of components and systems into future and current ships, and providing power and energy system solution alternatives to new and existing platforms. Existing ships' power systems require optimized integration via energy storage and advanced controls techniques to withstand the effects of DE and other high powered mission systems and avoid negative impacts to power generating equipment (diesel/gas turbine engines and generators). Component and system prototyping and demonstration integration methods employed include advanced digital engineering and modelling and simulation, through land based hardware testing at various Navy, Academic and industry facilities, and through at-sea demonstrations of technological readiness and fitness for service to pace and inform development of ship requirements. The Navy's DDG(X) (formerly known as Large Surface Combatant) Program is the Navy's Future Guided Missile Destroyer ship acquisition program to follow the DDG 51 class that is essential to field capabilities required for the future fight as validated by the Future Surface Combatant Force (FSCF) Initial Capability Document (ICD), FSCF Analysis of Alternatives (AoA), and Future Naval Force Structure (FNFS). DDG(X) is initiating a phased systems engineering approach where risk is incrementally reduced to the necessary level to support performance of follow-on design and construction activities. This four-phased testing and risk reduction approach builds assurance that the IPS system can be installed and activated efficiently by the shipbuilder with performance characteristics that are well understood. Phase 1 (Digital Engineering) includes establishing a description of the components and system non-real-time models that are needed for the DDG(X) effort initiating the IPS digital engineering effort. This ensures requirements, specifications, and other important factors that determine intended use and performance bounds are defined. Persistent digital engineering efforts initiated as part of Phase 1 extend through the life of the DDG(X) program and have been conducted primarily at FSU CAPS. Phase 2 (Surrogate Testing) employs refined digital models and full-scale integrated surrogate components that functionally represent the intended DDG(X) power and propulsion system for testing at ITF. These models and surrogates support the build specification and guide the connection of equipment and interfaces at the ITF. Phase 3 (Tactical Hardware Testing) develop and transition ITF to the DDG(X) Land Based Engineering Site (LBES), builds a full-scale tactical representation of the shipboard power and propulsion system. Phase 4 (Shipboard Test & Activation) conducts shipboard integration testing of the power and propulsion system with other ship systems to confirm performance as specified in the contract requirements and interoperability at the platform level. Phases 2 and 3 are being conducted primarily by Naval Surface Warfare Center Philadelphia Division (NSWCPD) in tightly coupled coordination with Florida State University Center for Advanced Power Systems (FSU CAPS) digital engineering efforts. Project developments are aligned with the Navy's 30 year shipbuilding plan and the Chief of Naval Operations Surface Capability Evolution Plan via the Naval Power and Energy Systems Technology Development Roadmap (TDR), which outlines the way ahead for future developments and provides a basis for coordinated planning and investment by the Navy and private industry. This project develops and transitions products that electrically integrate and provide power to mission systems, integrates those components and systems into ship platforms, increases energy efficiency, and provides cyber security capabilities for current in-service Hull, Mechanical and Electrical (HM&E) systems as well as future systems. The systems developed by this Project are the power and energy foundation of the ships kill chain, and are developed with efficiency requirements as part of total life cycle cost minimization. Efforts within Power and Energy Systems are to design, develop, test and integrate shipboard power systems to incorporate advanced sensors, directed energy and other advanced weapons. Design and testing includes modeling and simulation, as well as land based testing, to reduce risk and demonstrate readiness for shipboard use. HM&E Cyber security develops and tests various cyber security hardware that monitors the HM&E network and system communications to detect potential cyber attacks. HM&E cyber security hardware will transition to appropriate back-fit and forward fit ship installations, as appropriate, once development and testing completes. The Cyber funding also supports using cyber analysis tools to identify potential vulnerabilities in HM&E enclave architectures, hardware components, and software for applicable surface ships. HM&E cyber security and analysis was previously referred to as Situational Awareness, Boundary Enforcement & Response (SABER) and is being renamed to more clearly identify the specific work scope within this PE which includes both SABER prototype HW development and HM&E cyber analyses.
