Guided by modeling and simulation efforts in the related ESRDC Impedance-based Controls task, commissioning and test plans were established.

Taganrog State University of Radio Engineering. The iggct 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.

Evaluate total ship mission effectiveness, and Those implementations must be even more robust, however, as much of the information they datashete is classified. Additional impedances to ground can be added for calibration purposes.

The voltage control loop takes as inputs the desired output voltage and the desired output frequency. This paper explores various power cable challenges for notional electric ship applications including future technology trends for shipboard power cables.

Second, with a standard modular power grid, maintenance and cost of repair to ship power systems would be more efficient and cost-effective. The primary reason for this failure to completely model the systems was related to the choice of simulation engine. A model of the ship was created in the Smart Ship Systems Design 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.

While in the arcing state, the breaker is modeled as a constant voltage source. From a heat generation point of view, the AES will produce significant thermal side effects that have the potential to produce catastrophic failures at both the system and component level.

The third simplification that has been made is that many components are datazheet in the abstract based on the operation goals of the component rather than on the details of what might physically be present.

I need service or support ABB Service. 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. Filtering of the feedback impedance was used to attempt to develop a compromise between stability and performance. igft

For the purposes of brevity and because of the resources available, model validation results are not presented herein. The model represents an ideal CCVS with gain factor. This report describes the on-going effort to define a process for developing a multi-level, rule-based design specification for naval ship electrical systems that can be implemented in the smart ship system design S3D enviroment.

This promising approach has been investigated on a very ratasheet set of components. Research results for the most recent six-month reporting period from October to March have been highlighted red in this report. The rack moves in the positive direction when the voltage at node A with respect to node B positive.

IGCT (Integrated Gate-Commutated Thyristor)

If the user chooses to use a specified heat transfer coefficient, thermo-physical properties are no longer required and this solve block is not called by the solver. Concurrent with this upgrade, a new study of the applicable power electronics models was initiated and reported here. The breaker finally switches from arcing to open state, when the current falls below the extinction current.

Indication of relative vulnerability of certain sections, components and subsystems to focus studies on their respective faults and failures An understanding of the need for detailed hardware information which would eventually lead to a more exhaustive hardware FMEA H-FMEA.

It is intended that alternative designs can be tested against this design; these alternatives may make adjustments such as replacing single pieces or classes of equipment, rearranging equipment using different topology and connectivity, or replacing entire support systems with systems using a different paradigm entirely.

A widely accessible accelerated simulation approach provides key Navy users with early capability to use emerging software approaches to modeling. Convection parameters can be accessed and changed before and during run time, providing a parametric approach to system behavior.

Navigate Search Login layouts-flyoutmenu-cart. The MVDC architecture with 12 kV DC distribution represents a shift from traditional 60 Hz AC shipboard power distribution system and has the potential to provide superior power density, power quality while being affordable.

Iterate until total ship mission effectiveness requirements are met. The datashee aspect was the development of a set of component models in mathematical form. The models set forth include: This simulation model is used as basis to develop a diagnostic tool to determine the remaining life of insulation materials by relating the fractal dimension of the tree to the supply voltage and datasheeg properties. This would help to enhance the detail of the overall analysis Help focus diagnostic efforts to manage identified risks using well established AI techniques or the need to develop novel ones Aid efforts to enhance decision support by tapping into the data-rich FMEA resources.

Property values are computed at each time step using curve-fitted equations derived from published tables. In addition, the toolset can be utilized with IMUs in order to create nonlinear models by extracting the terminal behavior of devices. This paper presents a model to simulate electrical trees in dielectric materials.

Thus, high-frequency dynamics have been neglected. The voltage magnitude is user specified arcing datashset parameter.

An analysis framework will be developed along with supporting software tools which takes into account the controllability of localized energy storage via the supervisory control approach and interface characteristics.

It only requires an external power supply and its control functions are conveniently accessed through optical fiber connections. The overall control of the inverter module contains a voltage control loop and a synchronous current regulator SCR.

For adaption to ship power system design, the major challenge was automated model partitioning and parallelization into subsystems of less computational burden to facilitate the use of legacy systems. This report details the specification of the notional ship and modeling thereof in Paramarine, the analysis and prioritization of the electrical load on the notional ship, the initial modeling of in-zone power conversion equipment, and the development of pertinent metrics, especially the vulnerability metric.

An extension of impedance measurement units IMU to the medium voltage MVmegawatt-class converter levels would provide significant benefits to the U.

This document will be updated as additional information becomes available, and the revision history will be tabulated above.

The server and the client parts with the same endpoint value represent one connection. The goal of the group is to arrive at a common Datasheey model with its characteristics defined such that implementation of the SPS model in various simulation platforms can be mapped, verified and validated.

In general the number of slots is large for distributed windings typically 6 per phase. The reader is then encouraged to review the list of igc at the end of this report to comprehend the full breadth of the achievements and to refer to the appropriate publications where this report provides insufficient information.
