The simulator, recently delivered by the University of Trieste to the Italian Navy, is utilized to study relevant electromechanical transients of the on board IPS. In particular, this simulator is employed in verifying some automated sequences and restore maneuvers, which are hard to be analyzed through on board tests. Other uses will be the support in crew training and the study of different control strategies. The developed IPS simulator has shown to be a tool able to help navy engineers and electrical staff in understanding some relevant behaviors in electrical transients, permitting the simulation of the system in a cheap but accurate way. A validating campaign of the numerical results is now on the way, referring to commissioning and sea trials results of the first built ship of the class.","PeriodicalId":119318,"journal":{"name":"2013 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"20 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":"123558852","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 conventional Z-source breaker does not provide steady-state overload protection and can only guard against extremely large transient faults. The Z-source breaker can be designed for considerations affecting both rate of fault current rise and absolute fault current level, analogous in some respects to a “thermal-magnetic” breaker. The proposed manual tripping mechanism enables protection against both instantaneous current surges and longer-term over-current conditions. The fault operation intervals of the proposed Z-source breaker topologies are demonstrated in SPICE simulation.","PeriodicalId":119318,"journal":{"name":"2013 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"1 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":"129716457","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 Modular Multilevel Converter allows a nearly unlimited cascading of voltage levels at the same complexity in construction. This allows to minimise unacceptable motor terminal overvoltages and motor insulation stress. A current-oriented control is mandatory for this drive control, because the Modular Multilevel Converter is not of the voltage-impressing converter type. For that reason, a novel state-control approach for induction machines is used to control this drive. The magnetising currents and the stator currents of the machine are the control signals. An overlaid control is used to balance the converter sub-module voltages. The basic ideas of the multivariable control of the introduced drive and the excellent control behaviour of a 17-level Modular Multilevel Converter feeding a 3.9-MW 4.16-kV induction machine are presented.","PeriodicalId":119318,"journal":{"name":"2013 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"2 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":"131335767","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 criterion is based on imposing passivity of the overall DC bus impedance. If passivity of the bus impedance is ensured, stability is guaranteed as well. The PBSC, in contrast with existing stability criteria, such as the Middlebrook criterion and its extensions, which are based on the minor loop gain concept, i.e. an impedance ratio at a given interface, offers several advantages: reduction of artificial design conservativeness, insensitivity to component grouping, applicability to multi-converter systems and to systems in which the power flow direction changes, for example as a result of system reconfiguration. Moreover, the criterion can be used in conjunction with an active method to improve system stability, called the Positive Feed-Forward (PFF) control, for the design of virtual damping networks. By designing the virtual impedance so that the bus impedance passivity condition is met, the approach results in greatly improved stability and damping of transients on the DC bus voltage. Simulation validation is performed using a switching-model DC power distribution system.","PeriodicalId":119318,"journal":{"name":"2013 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"167 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":"122622638","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}

Despite the great achievements in single-stress aging mechanism, much less is known about the multi-stress aging and the associated phenomena. The cables will suffer from the electrical stress, thermal stress, mechanical stress, and other aging factors during the operation, which will initiate the unwanted aging of the cables. In the study, the accelerated electrical aging of Ethylene Propylene Rubber (EPR) cables was carried out. The 15 kV EPR cables were stressed by 3V0 (26 kV) ac voltage with switching impulses superimposed. The ac current of ampacity (226 A) was applied to simulate the thermal stress at full load. The major objective of the study is to obtain a comprehensive understanding of the accelerated aging phenomena of EPR cable insulation and the impacts from different aging factors.","PeriodicalId":119318,"journal":{"name":"2013 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"22 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":"127601920","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 two main contributions of this paper are the development of a new peak-current based control which ensures that load fault currents do not propagate through the system and the derivation of an average-value model for the chosen converter topology with the aforementioned control. The proposed control strategy is shown to yield excellent fault performance. The average-value model (AVM) accurately captures most low-frequency dynamics and is much faster to evaluate than a waveform-level model which includes switching. The subject converter and its control are intended for use in a part of a larger distribution system and, in particular, a shipboard DC power system.
