The basic DTC scheme is characterized by the absence of coordinate transformations, current regulators and PWM signals generators. In spite of its simplicity, DTC allows a good torque control in steady state and transient operating conditions to be obtained. However, the presence of hysteresis controllers for flux and torque lead to torque and current ripple and variable switching frequency operation for the voltage source inverter. This paper is aimed to briefly recall DTC principles and their intrinsic problems, and to discuss possible control strategies to improve the operating characteristics. Due to its basic principle, DTC technique is well suited for exploiting the improved number of voltage vectors available with multilevel and multiphase converters. A discussion is also carried out in order to emphasize the potentiality of induction motor drives based on these new power converter topologies.","PeriodicalId":133392,"journal":{"name":"2013 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133704950","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}

Large 4-pole turbo-generators reach 2191 MVA with torques of 12.6 MNm. This torque-level is even small in comparison with the Three Georges hydro generators, which have less speed and reach up to 96MNm. The market of both kinds of machines is a very limited one. The backbone of the energy market is given by gas-turbine-and wind-turbine driven generators. Beside smaller asynchronous and synchronous generators up to 6 MW, which are driven by the wind-turbine over a gearbox, direct drives are used with large synchronous generators either with permanent magnets or a field winding in the rotor. Generators with large numbers of machines per year as well as extreme large generators are based upon highly sophisticated design and calculation methods. Salient 4-pole synchronous generators for instance must be very reliable and optimized in design due to the number of machines, which are going into application each year. The development process is based for all large synchronous generators on analytical and numerical calculation methods. Numerical field calculation is a powerful tool for the design in these electrical machines. Developed methods and programs enable the skilled engineer to solve challenging field problems, which occur in reality. Analytical methods are nevertheless the backbone to calculate synchronous generators as a whole or to evaluate design modifications close to a verified design point.","PeriodicalId":133392,"journal":{"name":"2013 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"246 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114374395","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 intensive research has been performed in order to improve performances of fault diagnosis techniques by applying enhanced signal processing methods during past few years. Since non-invasive sensors offer relatively simple and cost effective fault diagnosis capabilities, more emphasis is given to stator current analysis rather than vibration or acoustic analysis for electrical machines. Here, further interests have been paid on modern signal processing techniques with a special attention to their performances in time domain, frequency domain and time-frequency domain. A comprehensive review is done on recently developed methods which are applied to the stator current collected from induction machine based test-rigs with electrical and/or mechanical faults. It will be demonstrated that numerous techniques have been adapted to induction machines diagnosis. They have been developed primarily based upon basic digital signal processing techniques in order to achieve a more reliable identification and quantification of fault indexes.","PeriodicalId":133392,"journal":{"name":"2013 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133146376","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}
