This project report details approaches and results of testing the first medium voltage, megawatt-power level IMU. It is a fundamental tenet of complex system design that early decisions have very serious consequences, both in the later stages of design and development, and in the operation of the ship.

Typically the cooling fluid is saltwater seawaterfreshwater, or chilled water. It is merely a somewhat realistic representative example for datasjeet electrical and thermal system concepts. The systems delineated in this document are a single, baseline reference ship.

Integrated gate-commutated thyristors (IGCT)

Learn more I agree. This model wraps a model created in ACSL. When natural coupled layer 1 this model functions as a voltage pressure, speed, ect. Filtering of the feedback impedance was used to attempt to develop a compromise between stability and performance.

First, throughout this report average-value models are used. Additional impedances to ground can be added for calibration purposes. The convection model developed for the VTB makes simplifying assumptions to minimize the solver computation time and to reduce number of independent equations that must be solved at each time step. This effort in this Task synergistically interacts with 5.


Discussions are underway to next open the link to research projects at the U. The relevant outputs are highlighted along with future directions for this particular research. They are pressed with a relatively high force onto heat-sinks which also serve as electrical contacts to the power terminals. For this country please use ABB’s partner contact details. This model represents a multiphase lossy transmission line.

Topic of research is the concept for the future All-electric ship of the United States Navy. With regard to the first aspect of this work, that is the component modeling, fundamental component models in mathematical form were defined in sufficient detail to represent a notional system using the three aforementioned architectures.

The igc is time dependent, and it is characterized by a look up table in an Excel spread sheet.

As a result of the research, investigations can now be performed for studying the experimental power system setup of Purdue University to support the research for All-electric ship.

In addition, a droop datasgeet is used to regulate the sharing between converter modules within each zone. Notional System Report Two – Rev Control volume with only conservation of energy employed across the boundaries Explicit and transient in datsaheet and with a lumped element spatial datashet spatial gradients cannot be resolved Thermal physical properties are temperature dependent with an option to remove this dependency Heat transfer by conduction and radiation are neglected The model uses two thermal nature ports and is represented schematically by a cooling fin.

The ship service converter module regulates the in-zone bus voltage. Note, that while SCR-type converters can interrupt fault currents at the next zero crossing of the AC current significant transients remain on the Iyct side.

The component heat exchanger removes waste heat from heat producing devices and the freshwater to seawater exchanger dumps the waste heat from the freshwater loop to seawater which is then discharged overboard.


The input and output ports are modeled as signal ports.

The model is based on the zonal integrated power distribution system architecture proposed by N. A generalized process for designing electric warships proposed dagasheet Doerry [1] consists of the following steps:.

Please datawheet again later or go to https: The breaker state changes from closed to arcing, when the RMS current through it exceeds its current rating. Calculate distributed system component ratings, 8.

In this system, the voltage regulator has two parts; a control algorithm to determine the field current of the brushless exciter, and a power converter which achieves this command. These models can be used to perform simulation studies.

Please make changes in the Word version of this document using track changes. The model represents an ideal CCVS with gain factor. Parallelizing the Simulation of Shipboard Power Systems. The model accounts for the characteristic tree patterns and the partial discharges associated with the propagation of trees.

IGCT (Integrated Gate-Commutated Thyristor)

This feature, in conjunction with the device’s fast transition between on and off state, enables short on-off pulse bursts with switching frequencies of up to 40 kHz. The RMS current is evaluated as the average of the square of the breaker current over datasheef user specified time interval. Navigate Search Login layouts-flyoutmenu-cart.
