This technique involves the use of Hall Effect sensors instead of the current transformer (CT) to measure and detect fault current and different wireless communication methods to send and receive the fault signal. The paper first analyzes and asses the risks associated with the use of a conventional CT and come up with test models to further support the use of Hall Effect sensors instead. Three case studies are presented describing the use of Hall Effect sensors as tools for diagnosing the problems with each potential wireless technology. The methods of wireless communication used are analog transmission and digital transmission. For analog transmission, the modulation techniques Amplitude Modulation (AM) and Frequency Modulation (FM) are tested. Comparative studies of cost related to existing and the proposed system have also been done.","PeriodicalId":119318,"journal":{"name":"2013 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"259 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":"123083694","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}

The power is then sent to a common electrical bus for allocation to both propulsion and non-propulsion electrical loads. Thus the gas turbine engine is dynamically coupled with the electrical system, and even with the thermal system, which is usually critical for the electrical system design. It has becoming increasingly important to understand the interactions that exist between the operation of the engine and the behavior of the electrical and thermal systems. This paper presents a co-simulation approach for cross-disciplinary simulations. Such an approach is implemented by integrating a twin-shaft gas turbine model, with a power generation and distribution system, and a thermal system. In this study, the thermal system is mainly used to manage the heat generated by the power converters in the electrical system. This paper discusses potential interactions that could take place during a dynamic disturbance of the fuel flow to the gas turbine engine. Preliminary simulation results for the dynamics of gas turbine power generation, power redistribution between the electrical loads, temperatures of power converters are presented to demonstrate the modeling and simulation capability, as well as illustrating the opportunities for further research.","PeriodicalId":119318,"journal":{"name":"2013 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"12 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":"125345431","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}

This paper presents a point-by-point comparison of the results produced by MATLAB/Simulink 2012a and in parallel by CEMSolver. A large shipboard power system model is used for the comparison.

A three phase bolted fault was taken as the mechanism for inciting potential instabilities. Simple rotor angle analysis leads one to believe that higher frequency power systems are inherently more unstable than lower frequency systems, and this point is substantiated by critical clearing time (CCT) tests. But more extensive simulation-based analyses paint a different picture: if circuit breaker speed can be increased proportionally to the increase of system frequency (e.g. opening after some number of cycles, irrespective of the frequency of those cycles), then higher frequency systems can have better stability than lower frequency systems. Conversely, if circuit breaker speed cannot be increased proportionally to system frequency, then higher frequency systems might present worse stability if no other method for improving system stability is implemented.","PeriodicalId":119318,"journal":{"name":"2013 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"137 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":"132276226","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}

A probabilistic model based Bayes' classifier is implemented to classify the current operation state of the ShipBoard Power System (SPS), depending upon the power system readiness for critical contingencies. Real power, reactive power, and generator status are taken as input features for the algorithm. Loss of vital/non-vital load is calculated by solving optimal power flow (OPF) to help build the knowledge base. Training data are updated online to increase the accuracy of the proposed approach. The characterization of the operation states helps the shipboard power management system to take the appropriate control action. Initial results from tests are presented and the outcomes from the particular techniques are discussed. Moreover, we also present RTDS based experimental framework towards the ongoing research on overall management system including the diagnosis support. Naïve Bayes' approach has classified the system states with 97.67% accuracy to new instances.

In contrast to microgrids emulating the land-based electricity grid, maintaining a steady bus voltage is no longer an objective here.
