Modeling and Simulation of Electric Ships’ Power System Components and Their Interaction
(Society for Computer Simulation International, 2007)
Models of propulsion motors, generators, gas turbines, and power converters are used to determine weights and volumes, evaluate designs, and predict performance of power system components for all-electric navy ships. The ...
Uncertainty Analysis of Large-scale Power Systems Using Collocation
Collocation algorithms for efficiently solving stochastic differential equations arising from modeling uncertainty in large-scale systems are presented. The resulting solutions are integrated to compute statistical moments, ...
Electric power system concepts for integration of advanced sensor and pulsed loads in the DDG-51 class ships
Advanced weapons and sensors increase demand on the electric power systems of Navy surface combatants, driving the need for fully Integrated Power Systems (IPS) such as those found in the DDG-1000 Zumwalt class of ships. ...
Development and analysis of trapped field magnets in electromechanical devices
High temperature superconducting trapped field magnets (TFM) offer great potential as an alternative to 2>d generation YBCO wire, both in cost and performance. Attention is given to the calculation of current distribution ...
Dynamic Load and Storage Integration
Modern technology combined with the desire to minimize the size and weight of a ship’s power system are leading to renewed interest in more electric or all electric ships. An important characteristic of the emerging ship ...
Power Grid for a Naval Electric Ship - AC versus DC
The debate over the best electric grid topology for an all electric ship has provoked discussion on a wide range of topics, spanning interconnection issues, transmission losses, and power preferences of electronic components, ...
Residential PVs and EVs: Before and After
Power distribution systems are experiencing higher load levels, unbalanced distributed generation, a wealth of load diversity, and more uncorrelated events than ever before. To provide quantitative information regarding ...
Rotating Machine Technologies for Integration of Pulsed and High Power Loads in Naval Electric Power Systems
Advanced electric sensors and weapons are placing increasing demands on the electric power distribution systems of future naval vessels and energy storage is viewed as a critical technology for effective integration of IPS ...
A collaborative early-stage ship design environment
Recent advances in sensor and weapons systems are significantly increasing the electrical power that is required and the thermal loads that must be dissipated onboard US Navy ships. Thus, design tools and methods must bring ...
