While a change occure in power systems i.e. a fault, loss of generation or changes in wind speed, in this study, Matrix Converters can properly improve the behavior of oscillatory system to be more stable. In this study, frequency of system is taken into consideration, frequency measurement is done by proper use of phase locked loop in different case studies. Two new structures base on sparse matrix converter (SMC) and also very sparse matrix converters (VSMC) introduces to be implement instead of B2B converters in DFIG wind turbine structures. The structure don't have any DC link. The model also compared with conventional matrix converter (CMC) uses with wound rotor induction generator. Symmetric sequence method utilized in the study for inversion and rectification stages of direct space vector strategy (SVM) for SMC and VSMC. For CMC indirect space vector modulation strategy (ISVM) used that expressed in detail. Two different models for wind turbine block proposed in the simulations to model shaft torque-speed behavior. Results show the consistency of the proposed structure to control frequency of the proposed power system when integrated to DFIG wind turbines base on VSMC and SMC matrix converters.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133403919","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 analytical and numerical approaches for prediction and calculation of acoustic noise radiated from electrical machines usually yield considerable errors. Therefore, the accurate investigation of acoustic noise in electrical machines necessitates exact experimental noise measurements. In this paper, an efficient experimental model is developed to analyze the acoustic noise radiated from a synchronous motor, identify the noise sources, and extract the significant natural frequencies. At first, the motor mechanical speed is raised from zero up to a maximum value by use of a Variable Frequency Drive. During the motor acceleration period, its radiated acoustic noise is measured by means of a “measurement microphone” in a standard test condition. The measurement results are then analyzed via developing and utilizing an Image Processing Algorithm, and thereby, the prominent noise sources of the synchronous motor and its significant natural frequencies are finally identified.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127167526","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}

By reconfiguring the two-level three-phase six-switch inverter and employing the four-switch (B4) topology during the post-fault condition, unceasing operation of the drive is attainable. In this paper a predictive torque control (PTC) scheme is proposed to control the B4 inverter-fed permanent magnet synchronous motor (PMSM). An extended cost function of the predictive scheme not only reduces the fluctuation of electromagnetic torque and stator flux, but also it reduces the voltage offset between the DC bus capacitors. The B4 inverter controlled by the proposed method reduces the switching losses and helps to tolerate several inverter faults. Proposed PTC method alleviates the unbalanced phase currents induced by fluctuation of DC bus center tap voltage. It provides an effective approach to reduce the harmonic distortions of the motor currents and relevant stator vibrations. It also suggests a systematic, automated approach for the tuning of applied Proportional-Integral controller in the speed control loop, which utilizes the fuzzy logic algorithm. Simulation results demonstrate the effectiveness and potentials of the proposed PTC method to control the post-fault B4 inverter-fed PMSM drive.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"162 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131423494","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}
