An alternative approach for winding design is the use of a concentrated bar winding with only one turn per coil, which reduces the effort and volume for insulation material and increases the slot fill ratio up to 80 %. Consequently, traction drives with higher power density, reduced mass and improved efficiency are feasible. The major challenge of this design approach lies in the massive winding bars that can cause effects of current displacement especially for high speeds and a high number of pole pairs. The present paper focuses on the primary reasons for the current displacement (like skin effect, proximity effect and the magnetic stray field) and introduces three possibilities to reduce these effects: conductor splitting, conductor rearrangement and different conductor wiring. Related consequences for winding and stator design are highlighted in aspects of motor losses, efficiency and operating performance.","PeriodicalId":199452,"journal":{"name":"2013 International Electric Machines & Drives Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115399592","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}

Traditional sensors based position detection methods not only increase hardware complexity and system cost, but also face severe challenges on reliability caused by the disturbances from the varying weather and harsh operating conditions in wind energy generation sites. Thus, with the aim of eliminating position sensors and developing a reliable position self-sensing technique, this paper proposes a position self-sensing control method based on sliding mode observer for a 2 MW permanent magnet synchronous generator (PMSG) wind turbine system. In addition, a three-level neutral-point-clamped (NPC) back-to-back converter with space vector pulse width modulation (SVPWM) is developed for the full-scale power conversion, which has lower voltage stress on the switching devices and less harmonic distortion in the output voltage compared with those in traditional two-level power converters. Simulation analysis is carried out to verify the effectiveness of the proposed self-sensing method and the three-level SVPWM based back-to-back NPC converter. The simulation results soundly justified the feasibility of the proposed control scheme and power conversion strategy.","PeriodicalId":199452,"journal":{"name":"2013 International Electric Machines & Drives Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130088082","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}

It is implemented using a closed loop feedback that senses the shunt capacitor smoothed generated voltage at the generator terminals. The voltage error feeds a PI controller that in turn governs the switches of the electronic converter used to drive the generator. With this approach the amount of energy stored in the winding in each cycle is controlled and leads directly to the control of the generated voltage. A mathematical model that considers magnetic saturation is used to represent the reluctance generator, which is driven by an asymmetric half bridge converter. An appropriate sequence of turning off the switches of each phase of the generator is shown to allow for a better usage of mechanical power in the electromechanical conversion process. Comparison with a standard switching strategy is included. An efficient technique to detect the right moment of firing the controlled switches is shown. Experimental and simulated results are compared and found to be in good agreement. The feasibility of the proposed strategy is demonstrated.","PeriodicalId":199452,"journal":{"name":"2013 International Electric Machines & Drives Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121495310","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}
