This paper presents a model to simulate electrical trees in dielectric materials. The goal of the group is to arrive at a common SPS model with its characteristics defined such that implementation of the SPS model in various simulation platforms can be mapped, verified and validated.

For the purposes of brevity and because of the resources available, model validation results are not presented herein. Power electronics converters of the megawatt class need to be characterized regarding their capacitive, inductive, resistive and radiative coupling to the datasgeet plane. For both test configurations, comparison of the empirical and simulation data showed an error calculated less than 8.

The Office of Naval Research is developing science and technology for advanced electric ships that utilize an integrated power system. Please select country from the list below.

ESRDC | Electric Ship Research and Development Consortium)

The power load CPL consists of a buck converter and a switching control that is designed to dissipate a constant power for a given input voltage range. The Electric Ship Research and Development Consortium ESRDC has created a notional ship for use as a test case in developing research to advance the state of the art in electric ship concepts.

The controls of the inverter have been developed to provide a means to control the speed or torque of a standard 3-phase induction machine. The arrangement is that the ict is provided on the web through a private link between NPS and the University of Texas at Austin.

The voltage at the input of the VTB model is sent to the Matlab function as input parameter, together with a flag to identify init phase. Multipole machines with salient poles are used for relatively slow rotation speeds whereas for higher speeds for example gas turbine driven generators the machines have lower pole numbers and cylindrical rotors – so-called turbo rotors.


Please fill in required fields. Such attributes are conveyed to the user through a custom dialog window. This project report details approaches and results of testing the first medium voltage, megawatt-power level IMU.

IGCT (Integrated Gate-Commutated Thyristor)

In particular, the set of models is iigct being used to study a notional medium voltage ac shipboard power system, a notional highfrequency ac shipboard power system, and a notional dc shipboard power system.

Currently, the Arleigh Burke DDG class destroyer employs five ton marine datasgeet units to handle active cooling of ship systems and components. In particular, the switching of the power semiconductors is only represented on an average-value basis. An important application area for the synchronous machine is large-scale power generation. Additionally, a notional time-based mission consisting of three mission segments was developed to compare the performance of each design variant against an operational vignette; selected results are presented in the report.

The daasheet focus adtasheet the study performed under this project was to provide the ship architect with information and tools for completing steps 1 and 5 for the design of the baseline MVDC ship electrical system.

One critical aspect was the pro-tection of experiments due to the uniqueness of the proposed tests. The relevant outputs are highlighted along adtasheet future directions for dagasheet particular research. Thermal management is considered an enabler for the technologies likely to appear on an AES. The task will take advantage of the infrastructure at FSU-CAPS to facilitate the proposed component datxsheet development and prototype testing and validation with the systems view in focus.

The goals of this exercise were twofold: The device’s control power consumption typically ranges from 10 – W. The need for hardware procurement and training costs coupled with the historical concerns over the longevity of special purpose computing have suggested this will be a valuable research tool, but it will not be widely adopted within the Navy and the shipbuilding industry.

In addition, a droop setting is used to regulate the sharing between converter modules within each zone. This gict to manage technological change has helped achieve superior capability. This report will include an update of the models presented herein, but also include examples of their application in the simulation of notional medium voltage ac, highfrequency ac, and dc shipboard power distribution systems. This is a research environment involving naval officers and the system is helping them improve the quality of their education during their limited time at NPS.


However, the introduction of advanced electronics and pulsed-energy systems on a surface ship is not without consequences.

There was a problem with your request. Also implemented is a stabilizing filter that acts to counteract the destabilizing influence of constant power loads [1].

A model of the ship was created in the Smart Ship Systems Datasheef S3D design environment, to include electrical, piping and mechanical schematics along with three-dimensional placement of equipment on a ship hull in a naval architecture view. The employed constant power load controller generates commanded inductor current.

The connection is a signal coupling done by modified nodal analysis. Determination of Remaining Life of Rotating Machines.

The model reads values directly off the Excel spread sheet rather than from a saved data file. The voltage control loop takes as inputs the desired output voltage and the desired output frequency.

Integrated gate-commutated thyristors (IGCT)

It is merely a somewhat realistic representative example for testing electrical and thermal system concepts. The primary objective of this project was to evaluate the suitability of such a novel instrument for use of frequency domain characteri-zation of megawatt scale equipment, which will eventually be used for system integration studies.

Furthermore, the guidelines and rules extracted through this task will be integrated into the S3D environment to enable applying well-established engineering principles to the automation of design evaluation.
