Semiconductor modules with medium-voltage (MV) Si IGBTs and anti-parallel silicon-carbide (SiC) junction-barrier Schottky (JBS) diodes are of interest in commercial and naval converters as they allow for significantly reduced switching losses and at present are more cost-effective than an all-SiC switch. A three-level converter is being built and tested using custom modules made with 60A (120A pulsed), 4.5kV Si IGBTs and SiC JBS diodes. This work provides a platform to de-risk and evaluate the integration of SiC JBS diodes at MV using commercial modulation strategies and gating electronics with standard industry topologies for a range of switching frequencies. A comparison of SiC JBS diodes for MV, such as the decrease in turn-on IGBT losses and the elimination of snappy or avalanche recoveries is reviewed, and ways to make SiC more cost effective via topology and packaging choices are discussed.
具有中压(MV) Si igbt和反并联碳化硅(SiC)结势垒肖特基(JBS)二极管的半导体模块在商业和海军转换器中很受关注，因为它们可以显著降低开关损耗，目前比全SiC开关更具成本效益。一个三电平转换器正在构建和测试使用定制模块由60A (120A脉冲)，4.5kV Si igbt和SiC JBS二极管。这项工作提供了一个平台，可以使用商业调制策略和具有标准工业拓扑的开关频率范围的门控电子器件，在MV下降低和评估SiC JBS二极管的集成风险。比较了用于MV的SiC JBS二极管，例如降低导通IGBT损耗和消除快速或雪崩恢复，并讨论了通过拓扑和封装选择使SiC更具成本效益的方法。

The paper will present an advanced technique for increasing reliability of power system apparatus in vessels by means of a permanent Partial Discharge (PD) monitoring with a DataBase application and Smart Alerts logic. Recent failures on cruise vessels have raised expectations on possible diagnostic systems to be applied directly on-board, able to raise alerts in case of major problems. Consequences of an unexpected stop of cruise vessels or warships are incommensurable economic losses due to reimbursements, penalties and unscheduled maintenance. The PD Monitoring system described in this paper has been implemented successfully in several cruise vessels, and case studies are presented.

A project is currently underway to develop a bi-directional advanced hybrid drive system (AHDS) for application to a future surface combatant. This system would support propulsion powered through ship service gas turbine generators, as well as ship service power supplied from the mechanical propulsion gas turbines. This paper discusses system studies currently being conducted to assess the requirements and implications of incorporation of two such AHDS units on a future surface combatant.

This paper proposes a novel modeling and simulation environment for ship design based on the principles of Model Integrated Computing (MIC). The proposed approach facilitates the design and analysis of shipboard power systems and similar systems that integrate components from different fields of expertise. The conventional simulation platforms such as Matlab®, Simulink®, PSCAD® and VTB® require the designers to have explicit knowledge of the syntactic and semantic information of the desired domain within the tools. This constraint, however, severely slows down the design and analysis process, and causes cross-domain or cross-platform operations remain error prone and expensive. Our approach focuses on the development of a modeling environment that provides generic support for a variety of application across different domains by capturing modeling concepts, composition principles and operation constraints. For the preliminary demonstration of the modeling concept, in this paper we limit the scope of design to cross-platform implementations of the proposed environment by developing an application model of a simplified shipboard power system and using Matlab engine and VTB solver separately to evaluate the performance with different respects. In the case studies a fault scenario is pre-specified and tested on the system model. The corresponding time domain bus voltage magnitude and angle profiles are generated via invoking external solver, displayed to users and then saved for future analysis.

We present a comparison of performance of an all-electric-ship (AES) simulator using two different approaches to control the induction machine in forward as well as in cash astern operations. The first approach uses a constant-slip control while the second uses direct-torque control. We also investigate the use of proper breaking resistors required for minimal power dissipation during the crash astern operation. The AES simulator describes a medium voltage DC system (MVDC) for the USS DDG-51 Arleigh Burke-Class destroyer.

The design of Shipboard Integrated Power System (IPS) with variable frequency drives (VFD) are considered challenging due to the random incorporation of various commercial, emerging, and intrusive technologies. The IPS designs are found to be creating system level anomalies such as instability of the electrical system. The instability is due to multiple electrical system noise issues such as; harmonics, transients, arc-flash susceptibility, waves, etc. The type of resistance grounding (RG) system selection for ungrounded power systems may also influence the electrical stability of the power system. These electrical instabilities lead to system level blackout, premature equipment failure, major arc-flash incidents, electrical fire, and unscheduled unpredictable equipment failures, all contributing to a heavy cost burden when operating the ship.

Synchronous generators (SGs) are vital ganglia of the ship. SGs supply survival/defense/attack systems, propulsion, etc., so deserving on-line monitoring. Rotor unbalances shorten bearing lifetime, with overheating and stator-rotor rubs. No technique is definitely established for on-line evaluation of rotor eccentricities (REs) in working SGs. Actual manual air gap checks are time-consuming, and require unit shut-down and dismounting. This paper shows a method based on measurement of split-phase currents in stator windings with parallel branches. A symmetrical component transformation reverts the split-phase currents in rotating space vectors. The (p±1)-order vectors provide an affordable estimation of REs in 2p-pole machines. Rogowski coils or current transformers can be installed in the terminal box, or on winding front-ends, for current measurement. A LabView virtual instrument (VI) was developed for method application. This paper also describes some tests carried out on board an Italian Navy's ship for on-line monitoring of shaft misalignments in a loaded 2MVA SG. Loads on board ships are usually unbalanced and may change suddenly. However, it is shown that the load-related unbalance can be separated from the eccentricity-related unbalance in the split-phase currents. Good assessment of air gap percentage reduction in the tested 2MVA machine was finally obtained.

We show that an inverter coupled energy storage system can be used to provide a soft-restart for the zonal loads by first operating in a “protected ride-through” mode, then pre-energizing the loads, and finally transfer the loads bumplessly to the main generator. This method decreases by over 50% the inrush currents associated with restarting the loads. The inverter is controlled to achieve a voltage and phase matched condition with the main generator before the load transfer takes place so as to minimize voltage or current oscillations associated with reclosure. This process, termed as “Fault-Aware-Soft-Restarting” can eliminate the problems of 1) Unwanted fault-feeding 2) Motor starting inrush currents that causes voltage dips and motor stalling in nearby load zones and, 3) Breaker reclosing transients that may damage line equipment or cause secondary trips.

Information-embedded multi-converter shipboard power systems are comprised of multiple independently operated converters that work together with electromechanical equipment. Their relations can produce a large variety of dynamic and static interactions that can lead to irregular behavior of a converter, a group of converters or the whole system. This inherent cross-regulation behavior may correspond to controller limit violations, which results in harmful operational situations during system disturbances. It is significant then to monitor the system during perturbations; their underlying dynamics exhibit trajectories that not only depend on their independent operation modes. Appropriate modeling is a key issue to power system analysis and warrants primary investigation. This paper addresses aspects of modeling and simulation of multi-converter based shipboard power systems with the inclusion of power electronic equipment dynamics and network control in the overall system model. The model behavior is evaluated with respect to changes in loading conditions and control parameters (local and network) and validated through simulation of a nonlinear observability formulation of the developed system model.

Technological advancements have been made in the field of electrochemistry leading to the development of energy storage devices that are more power dense than ever before. Coupled with their already modestly high energy density, this makes them well suited for use as the prime power source of many high pulsed and continuous power AC and DC loads operated within MicroGrid architectures. The energy storage devices of interest as well as the MicroGrid concept are both technologically immature. Their independent performance characteristics as well as the manner in which they can be integrated with one another need further research in order to understand their limitations and how they will perform in an extreme environment where high pulsed and continuous power loads are sourced simultaneously. With support from the US Office of Naval Research (ONR), a novel MicroGrid test-bed at UTA is being used to characterize how the power quality of different generation sources, including various low impedance energy storage technologies, solar panels, wind turbines, fuel cells, and fossil fuel based generators, are impacted when they are interconnected and used to source these types of high power loads. A description of the experimental setup and some experimental results obtained will be presented.
