This model is created using a FEM simulator. The modeling of this machine by the finite element method will allow us to determine its magnetic characteristics: inductances, magnetic flux and electromagnetic torque. We will study specifically the evolution of the inductors in several positions of the rotor. The angular position of the rotor (θ) and the phase current (i) will be used as parameters. The results obtained by the finite element are compared with those obtained by the analytical method.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133238874","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 treated faults are concerned with the inverter internal faults, the DC-link fault and one isolated phase of the inverter. The consequences of the mentioned failure modes are analyzed. A study of the impact of each fault on the induction motor behavior is being investigated. The work is carried out using an inverter fed induction motor with an SVM-Back stepping control technique. A detection technique based on the stator current spectrum analysis is also proposed to detect and locate both the open-circuit switch and short-circuit switch faults that may occur in the inverter. The obtained results illustrate well the effectiveness of the detection technique as well as the various degraded operations of the motor due to the different faults associated with the inverter.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123959594","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 dryer is composed of a tunnel connected to a hot air production unit. Two types of solar generators have been studied: the first is an air flat plate collector and the other is a cylindro-parabolic concentrator. By carrying out mass and energy balances, we have established two theoretical models describing the functioning of the two systems. The simulation on MATLAB allowed us to determine the different temperature levels of different components and the moisture levels of the phosphates eliminated by the solar energy in each installation. The results obtained show that the use of a solar concentration system makes it possible to better conduct the phosphates drying since it has decreased its moisture content from 18% to about 2% while the plane collector reduces it only by 2.5% for the same quantity of 50 kg.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126744985","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 left vertical wall of the cavity heated to a temperature (Th) while the right wall cooled to a temperature (Tc), the horizontal walls of cavity are kept adiabatic. A numerical program written in COMSOL Multiphysics software, was developed, to solve the Navier Stokes and energy equations, under the Darcy-Brinkman formulation. In order to investigate the viscous dissipation effect a comparison is made between four models. Moreover, the entropy generation and Nusselt number were studied as a function of Darcy number. The results show that the influence of the different viscous dissipation models on the entropy generation strongly depends on the Darcy number and can in some case reverse the heat transfer from the fluid to the heated wall.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126516490","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}
