The common dc-link configuration significantly simplifies and reduces the costs of the topology but allows the Zero-Sequence Current (ZSC)to flow freely in the system. The Zero-Sequence Voltage (ZSV)produced by the two two-level Voltage Source Converters (VSCs)and the non-sinusoidal machine back-electro magnetic force (back-EMF)are responsible for the flow of additional current and the reduction of the overall system efficiency. The FCS-MPC is considered for the first time in this application as a simple solution to achieve both machine control and the ZSC suppression simultaneously. The main drawback of the FCS-MPC is the high amount of calculation necessary, here a different formulation of the FCS-MPC is proposed to significantly reduce the computational effort required.","PeriodicalId":378634,"journal":{"name":"2019 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125003450","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 investigates the possibility of using acoustic signals to detect various wind turbine drivetrain defects, and proposes an enhanced wind turbine main drivetrain monitoring solution, where acoustic analysis is combined with electrical and vibration analysis via Gaussian model-based fusion algorithm. A 25hp wind turbine simulator is set up in the lab and is used to validate the proposed fusion algorithm. It is shown by experimental results that the proposed fusion-based monitoring solution significantly outperformed solutions using individual signals in detecting drivetrain gear and bearing defects at different load and speed operation conditions. This work turns out to be the first effort to fuse/combine acoustic, electrical and vibration signatures to monitor wind turbine main drivetrain anomalies.","PeriodicalId":378634,"journal":{"name":"2019 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128810610","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}

However, a machine may not achieve the desired operating range under given boundary conditions of a drive train system. Several methods have been examined in literature that aim to extend the operating range, for example, star-delta-switching or pole-amplitude modulation. In this work, the influence of different winding configurations of an existing induction machine is investigated considering their potential for operating-range enhancement. Ultimately, none of the configurations is able to meet all the requirements due to, for example, current or voltage limitations. Therefore, alternative methods are investigated in this work and, finally, switched stator windings, also called series to parallel switchover, are employed to combine the advantages as well as the operating ranges of two single winding configurations. The simulation as well as experimental results show a considerably extended operating range especially at higher speeds and prove the feasibility of the proposed method.","PeriodicalId":378634,"journal":{"name":"2019 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"2018 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121325297","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}

Several different rotor and stator topologies are discussed and simulated to determine their suitability for high-speed operation. Finally, the most promising concept is implemented as a prototype. To the author's best knowledge for the first time a bearingless high-speed slice motor with slotted stator is manufactured. The slotted stator features the advantage of reduced magnetic air gap compared to motors with toroidal air-gap windings and slotless stator. The smaller air gap leads to increased air-gap bias flux and increased stiffness values as well as higher force and torque constants. Additionally a damper winding is included to suppress tilt motions.","PeriodicalId":378634,"journal":{"name":"2019 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131840696","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 proposed motor with LTP-MnBi for the rotor-core magnet and SrM for the flux-directing magnet shows the increased torque by 7.1 % and 12.5 % at 20°C and 125°C, respectively, and decreased torque ripple by 50 % and 62.9 % at 20°C and 125°C, respectively, as compared to the conventional rotor. According to the demagnetization analysis, the proposed motor is far less vulnerable to irreversible demagnetization than the conventional motor.

Due to the lack of accurate and fast calculation methods empirical values are widely-used. Empirical values are strongly dependent on the developer's experience. In case of new machine designs underestimating end-coil's leakage inductance can lead to serious failures that degrade the predicted operating behavior. This paper uses an approach to calculate end-coil's leakage inductance by combining the Neumann-Integral and the Method of Images. The method has been applied to concentrated windings and hairpin windings which are commonly used in traction applications. The results can be used to improve existing calculation methods which are usually based on analytical approaches and 2D-Finite-Element-Analysis (FEA).
