This type of generators is installed at the shaft of the main propulsion diesel engine while they are capable of operating as propulsion engine boosting devices if suitable power electronics are used. In this paper an effort is made to provide a comprehensive analysis of shaft generator role in ship power system efficiency improvement in relation with ship operation optimization point of view. Special reference is made to the interdependence of SG with power management system as they alter the operation point of both propulsion engine and the electrical generators affecting the optimal operating point.","PeriodicalId":243822,"journal":{"name":"2012 Electrical Systems for Aircraft, Railway and Ship Propulsion","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129806307","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}

For being able to run on these tracks, Operators require different types of trains, each one adapted to the specific characteristics of the line. This fact prevents scale-economies to be applied to the sector, managing in a less efficient way peak and valley demands as well as maintenance tasks. Talgo Hybrid Train is the perfect and long-time demanded solution for this problem. It can run on both electrified and non-electrified lines, and within electrified lines both AC and DC supply is supported. Furthermore propulsion bogies have been designed to allow dynamic gauge change. Talgo Hybrid Train is an all-track train that provides maximum interoperability, eliminating railway barriers since one train is enough to operate on almost any line.","PeriodicalId":243822,"journal":{"name":"2012 Electrical Systems for Aircraft, Railway and Ship Propulsion","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130811847","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 novel control architecture transforms the vehicle speed reference into a suitable motor speed reference and then guarantees the motor speed regulation to the corresponding reference on the basis of the motor speed regulation error. The motor speed measurement, which is typically available in electric vehicles, is used not only for traction control but for regulation purposes as well. The closed loop on-line identification of the three critical uncertain parameters allows for on-line estimating and imposing the motor flux modulus reference value which minimizes power losses and improves power efficiency.","PeriodicalId":243822,"journal":{"name":"2012 Electrical Systems for Aircraft, Railway and Ship Propulsion","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133262758","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 open slot design, combined with rotor permanent magnets, can produce remarkable cogging torque effects.

The new wedge concept is applied in the paper to a 12-slot surface permanent-magnet motor. Finite-element analysis is used to study the wedge design effects on motor phase inductance and cogging torque amplitude.","PeriodicalId":243822,"journal":{"name":"2012 Electrical Systems for Aircraft, Railway and Ship Propulsion","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134086325","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}

An electrical load management based on fixed priorities of the loads is considered a conventional implementation as applied in today's aircraft systems. It can cut and reconnect loads depending on their importance. The advantages and disadvantages of such a system are presented. Further implementations are depicted that are able to eliminate certain drawbacks of such a typical load management. Most promising is the exploitation of so-called slow responding loads which can be handled like an electrical storage. The optimization potential on future energy management functions is finally discussed and conclusions are drawn.","PeriodicalId":243822,"journal":{"name":"2012 Electrical Systems for Aircraft, Railway and Ship Propulsion","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132911465","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}
