The model was performed employing COMSOL Multiphysics software and analysis of the device was carried out in order to study the sensing behavior of the device when different substrates and different VOC gases are applied. The results indicate that, among the investigated substrates, Lithium Niobate shows the lowest total displacement with a value of $5.17times 10^{-4} mumathrm{m}$. The value is associated with a frequency shift value of about 233.5949 Hz and a highest SAW resonance mode at an approximated value of 855 MHz. On the other hand, Barium Sodium Niobate substrate shows the highest frequency shift value of about 281.5899 Hz. Indeed, the SAW device is simulated under the influence of several VOCs. Furthermore, investigation of the thickness of the polyisobutylene (PIB) thin film sensing layer with Lithium Niobate as a substrate shows that the frequency difference between the resonance frequency before and after applying the Dichloromethane (DCM) VOC, reaches its maximum value of ∼1650 Hz at a PIB layer thickness of about $1.4 mumathrm{m}$.","PeriodicalId":131382,"journal":{"name":"2020 7th International Conference on Electrical and Electronics Engineering (ICEEE)","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123177149","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}

In the absence of the speed sensor, we use a MRAS (Model reference adaptive system) observer to estimate the mechanical speed. In the MRAS method, the magnetizing current of the adaptive model is compared with that of the reference model. The rotor speed, the stator and rotor resistances are estimated from the magnetizing currents difference of the two models using adequate adaptive mechanism. The choice of this Observer is due to its simplicity, less computation time and good stability. For the choice of multi-level converter, we use five-level cascaded H-bridge inverters to feed the induction motor. This multi-level converter allows to obtain a greater number of output voltage levels with a very acceptable harmonic spectrum. The present approach (IFOC, MCHI and MRAS) helps to achieve a good dynamic response at low speed with reduction of total harmonic distortion. Simulation results show the effectiveness of the proposed method with consideration of variation in thermal parameters.","PeriodicalId":131382,"journal":{"name":"2020 7th International Conference on Electrical and Electronics Engineering (ICEEE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123568118","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 important factors of the electrical power system such as efficiency, safety, and total losses are also affected by the power transformer. One of the most important factors for the designing of the power transformer is electromagnetic forces. In this paper, electromagnetic forces of the power transformer are calculated by using the finite element method with the help of two-dimensional models. When the transformer's windings are in the original initial designing position, the current and electromagnetic forces of the routine and short-circuit circumstances are familiar to the transformer designers. However, the effect of the displacement of the transformer's windings on the electromagnetic forces is not well known to the transformer designers. In this work, electromagnetic forces during the non-displaced (normal conditions) and displaced windings of the transformer are examined by using finite element analysis. The main aim of this study is to investigate the radial and axial force of the displaced winding. Numerical results of the radial forces of the non-displaced windings are also compared with the analytical technique.","PeriodicalId":131382,"journal":{"name":"2020 7th International Conference on Electrical and Electronics Engineering (ICEEE)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132283214","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}
