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.","PeriodicalId":119318,"journal":{"name":"2013 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114292069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":119318,"journal":{"name":"2013 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130511885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":119318,"journal":{"name":"2013 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126184997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":119318,"journal":{"name":"2013 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130266148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
