The approach of concurrent design and development (concurrent engineering) was emphasized. Since accurate computer simulation could be used advantageously in all stages of component and system design and development, simulation becomes a necessity if this type of engineering approach is to succeed. Since 1987, PC Krause and Associates (PCKA) had been involved in the development of computer models for the Navy (NSWC). The computer models which were being used by NSWC to design and investigate Navy related power systems were developed and originally coded in ASCL by PCKA. The need for simulation in the Navy’s concurrent engineering approach to the Advanced Surface Machinery Programs was made very apparent at the Industry Brief. Coupling this with the fact that (PCKA) was instrumental in developing the simulation capability of NSWC provided the impetus for this contract. PCKA had not become involved with the manufacturers other than through or with the Government agency. This enabled PCKA to provide an independent evaluation. As a result of this independence and the fact that PCKA had an excellent working relationship with industry allowed PCKA to play its first role as an honest broker.

Period: 6/30/94 to 6/30/99 Principal Investigator: Paul Krause Brief Description and Purpose: It became clear that computer simulation would play a major role in the Navy’s Advanced Surface Machinery and the Advanced Electrical Power System programs at CDNSWC. In particular, accurate computer simulations could be used advantageously in all stages of component and system design and development. Simulation is a necessity if concurrent design and development (concurrent engineering) is to succeed. Since 1987, P C. Krause and Associates (PCKA) had been involved in the development of computer models for the Navy (NSWC). The need for simulation in the Navy’s engineering approach to advanced machinery and electrical systems coupled with the fact that PCKA had been instrumental in developing the present simulation capability of NSWC provided the basis for this contract. PCKA provided the Navy with engineering services in the area of detailed and reduced-order modeling and analysis of components/systems which were being contemplated and/or developed in the advanced machinery and electrical systems programs. Since PCKA had not been involved with manufacturers other than through or with the Government agency. This enables PCKA to provide an independent evaluation since the personnel associated with PCKA had not received corporate grants or contracts from manufacturers which could be construed as a conflict of interest. Here, again, PCKA was successfully casted in the role of an honest broker.

Period: 9/30/99 to 9/11/01 Principal Investigator: Paul Krause Brief Description and Purpose: In the mid to late 1990’s, PC Krause and Associates (PCKA), Purdue University, the University of Missouri-Rolla (UMR), and the University of Wisconsin-Milwaukee (UWM) had been extensively involved, as a group, in research, analysis, simulation, and design of power-electronic based systems for government agencies (Navy, Air Force, NASA, and the Army) interested in the more-electric initiative program. This group, of which PCKA was the small business arm, evolved naturally from a need to combine expertise in order to conduct the required work which has involved a large spectrum of power/drive systems ranging from spacecraft to tactical vehicles. The commonalities that exist between these many systems in configuration and components became very apparent. This sole-source contract was the first effort by the Navy to encourage interagency interaction in sharing the results of the research and engineering projects common to shipboard power systems and to provide a convenient funding vehicle to encourage shared funding, among these agencies, for projects of mutual interest. Clearly, this is in keeping with the emphasis on interaction and consolidation of government-funded programs. This contract was one of the first steps toward the goal of establishing an inter-agency funded group made up of universities, government agencies (laboratories), and industry and focused on the research, analysis, design, and development of electric power systems.

This set the stage for developing reduced order models for the components of the shipboard electric power system and to use the detailed computer models as a means of verifying the reduced order models individually and in a system configuration. Development of reduced order models and the equations necessary to connect these models in any feasible system configuration is the first objective of the proposed research. The second is to begin defining transient and dynamic stability and system security for a finite inertia electric system for normal and emergency operating conditions. Achieving these goals is necessary in order to provide a means to design and investigate the performance of proposed shipboard electric power...
Read MoreAffordable Unmanned Underwater Vehicle (UUV) Power System Architecture
Type of Awards: SBIR Phase I with IEDC Subcontractor: University of Illinois Contract Numbers: N00014-09-M-0330 Agency: U.S. Status: Completed Periods: 8/20/2009 to 1/25/2010 Principal Investigator: J. R. Wells Abstract: The primary objective of the proposed work is to develop an unmanned underwater vehicle (UUV) power system architecture that is simultaneously scalable to multiple UUV sizes, light weight, affordable, and adaptable. This will be accomplished through the development of “smart” power units (SPU’s) that can be readily interconnected to provide distributed and coordinated power management for the UUV while providing battery cell balancing and charge monitoring. The SPU’s will contain integrated power converter/controllers capable of providing for the vehicle hotel and propulsion loads, and compatible with multiple battery chemistries through the use of an automatic identification scheme. The SPU’s will facilitate universal charging through a standard interface port, be modular enough to be deployed in a wide range of UUV sizes and dimensions, and be capable of communicating both with other SPU’s and with the user using standard communication protocols. Deployment of the proposed SPU’s will be greatly enhanced by accompanying software capable of rapidly sizing and configuring the modules for a given UUV size while minimizing size and...
