- Description
- Broad Agency Announcement (BAA) Research Opportunity Description The Naval Sea Systems Command (NAVSEA) is interested in White Papers for long and short term Research and Development (R&D) projects that offer potential for advancement and improvements in the implementation of shipboard Integrated Power Systems (IPS) at the major component, subsystem and system level. IPS provides total ship electric power including electric propulsion, power conversion and distribution, combat system support and ship mission load interfaces to the electric power system. The flexibility of electric power transmission allows power generating modules with various power ratings to be connected to propulsion loads and ship service in any arrangement that supports the ship's mission at the lowest total ownership cost (TOC). Systems engineering in IPS is focused on increasing the commonality of components used across ship types and in developing modules that will be integral to standardization, zonal system architectures, and generic shipbuilding strategies with standard interfaces that are Navy controlled. The modules or components developed will be assessed for applicability both to next generation shipboard electrical architectures and combat systems and to back-fit opportunities that improve the energy efficiency and mission effectiveness in the current fleet. NAVSEA wishes to continue to improve IPS by performing analysis, modeling and simulation, life cycle cost analysis, producibility studies, module development, ship integration, architecture design, ship electric architectures and support for high power weapons systems requirements, and related efforts. An evaluation of emerging technologies for ship applications (such as fuel cells, support for high energy weapons, support for high power radars, high-speed generators, and advanced power electronics) to determine future feasibility and development requirements will be conducted. The approach to hardware developed under this BAA is that it fosters modularity and scalability (so that families of products may be leveraged to multiple potential applications) and shall accommodate an open system architecture where interfaces are well defined and mutually accepted. Electric Ships Office: The Navy has initiated the Next Generation Integrated Power Systems (NGIPS) effort with centralized leadership by the Electric Ships Office (ESO). The mission of the ESO (PMS 320, organizationally a part of the Program Executive Office - Ships) is to develop and provide smaller, simpler, more affordable, and more capable ship's power systems for all Navy platforms by defining open architectures, developing common components, and focusing Navy and industry investments. The ESO will provide leadership of the developments identified as part of this BAA, will direct the transition of associated technologies developed by the Office of Naval Research (ONR), and will manage the technology portfolio represented by Program Element (PE) 0603573N (Advanced Surface Machinery Systems) for transition into existing and future Navy ships. The guiding document that will be used to define the module developments that advance the NGIPS vision is the Next Generation Integrated Power System (NGIPS) Technology Development Roadmap, Naval Sea Systems Command Ser 05D/349 of 30 Nov 2007, which is publicly available under announcement N00024! 08R4123.NGIPS: The areas of focus for White Papers and Proposals submitted in response to this BAA should include, but are not limited to, the analysis, development, risk reduction and demonstration of future shipboard electric power systems and components, emphasizing shipboard power generation, propulsion, conversion, distribution and control; power quality, continuity, and system stability; electric power system/component level modeling and simulation; energy storage technologies; electrical system survivability; simplicity and ruggedness. The Integrated Power Architecture provides the framework for partitioning the equipment and software of NGIPS into modules and defines functional elements and the power/control and information relationships between them. For power generation, high power distribution, propulsion, and large loads, the NGIPS architecture includes Medium Voltage AC power (with emphasis on affordability), High Frequency AC power (with emphasis on power density in the near term), and Medium Voltage DC power (with emphasis on power density and fault management in the far term). For ship service electrical loads, NGIPS includes zonal electrical distribution which may be either AC or DC, depending upon the specific application. In addition to a full IPS implementation, modules that support a paritally integrated power system, or Hybrid Electric Drive (HED) where mechanical propulsion is augmented by rotating machinery off of the propulsion train for propulsion, or additional power generation shall be considered. Also of particular interest are technologies that result in significant energy efficiency and/or carbon footprint improvements over existing propulsion and power system technologies. The NGIPS roadmap partitions the power system components functionally into modules. Those modules, subsystems and systems of interest include the following. Power Generation Module (PGM): A Power Generation functional element converts fuel into electrical power. The electrical power is transferred to one or more Power Distribution functional elements. An associated Power Generation module might typically consist of a gas turbine or diesel engine, a generator, a rectifier (either active or passive), auxiliary support sub-modules and module controls. Other possible technologies include propulsion derived ship service (PDSS), fuel cells, or other direct energy conversion concepts. Power Generation concepts include 60 Hz wound rotor synchronous generator driven directly by a marine gas turbine (up to 30 MVA rating); 4 pole, 120 Hz, commercially derived or militarized design variants of the above; and higher speed, higher frequency, high power density variants of the above with high speed or geared turbine drive. The specific design issues to be considered include fuel efficiency, machine insulation system characteristics, size, weight, cost, maintainability, availability, harmonic loading, voltage, power, fault protection, voltage and frequency response to large dynamic loading, interface to main or ship service bus, and commercial availability. Power Distribution Module (PDM): A Power Distribution functional element transfers electrical power between other functional elements. Fault protection systems should be designed, if possible, to not require the power distribution modules to communicate control signals with any functional element other than system control. An associated Power Distribution module might typically consist of bus duct, cables, switchgear and fault protection equipment. Power Conversion Module (PCM): A Power Conversion functional element converts electrical power from one form to another. An associated Power Conversion module might typically consist of a solid state power converter and/or a transformer. Advanced topologies and technologies, such as the application of wide band gap devices, will be considered. Power Load Module (PLM): A Power Load functional element is a user of electrical power received from one or more Power Distribution functional elements. The area of interest for NGIPS in the Power Load is the load interface definition and the provision of specialty power to optimize that load interface. Among the special load interfaces that would require development are support for pulsed power weapons and sensors such as radar power supplies, electromagnetic launchers (for example EM Railgun), and advanced laser systems, all of which would benefit from optimized integration with the shipboard power system. This would enable real time data and asset management and reconfiguration based on demand. Propulsion Motor Module (PMM): Electric propulsion motors and propulsion motor drives are large electrical loads as well as NGIPS modules. Candidate propulsion motor concepts include Permanent Magnet Motors (radial air gap, axial air gap, or transverse flux), Induction Motors (wound rotor or squirrel cage), Superconducting field type (homopolar DC or synchronous AC). The drivers and issues associated with these designs include acoustic signature, noise (requirements, limitations, modeling, sources, and mitigation methods), shock, vibration, coolant temperature, manufacturing infrastructure, machine insulation system characteristics, commercial commonality, platform commonality, cost, torque, power, weight, diameter, length, voltage, motor configuration, and ship arrangements constraints. Motor drives that may be explored include cycloconverter (with variations in control and power device types), pulse width modulated converter/inverter (with many variations in topology), switching (hard switched, soft switched), and matrix converter (with variations in control, topology, cooling, power device type). Technologies for drives and rotating machines which allow the ability to operate both as a motor and a generator to facilitate a propulsion derived ship service (PDSS) installation or on a fully integrated power system to leverage the inherent energy storage in the ship's motion may be explored. Integrated motor/propulsor concepts may be considered either as aft-mounted main propulsion or as a forward propulsor capable of propelling a ship at a tactically useful speed. Energy Storage Module (ESM): An Energy Storage functional element stores energy. A number of alternative energy storage technologies and/or configurations (location within the distribution system and capacity) may be considered for future ship applications, such as battery, capacitor-based, fuel cell, fly wheel, or superconducting energy storage. Shipboard power quality and continuity along with examination of the implications of future high power/pulse power loads on configuration/technology alternatives is critical. Energy storage modules may consist of short term (micro/milli second) or long term (minutes/hours) energy storage applications which utilize a combination of technologies to minimize power quality and continuity impacts across the system. Power System Control (PCON): A System Control functional element consists of the software necessary to coordinate multiple other functional elements. A System Control Functional Element receives information from other functional elements and external (non-IPS) systems. Similarly, a System Control functional element may receive control commands from or negotiate control actions with external systems and other functional elements. System Control manages the power and energy flow within the ship to ensure power is delivered to the right load in the right form at the right time. While various forms of power control have been implemented on commercial IPS ships, the survivability requirements for military ships combined with the pulse load characteristics for some of the loads described above will require more sophisticated algorithms than are commercially available. A System Control functional element resides on an external distributed computer system and therefore typically does not include hardware elements (unless specialized hardware is required).
