A rotating conductive disk is placed in front of calculated number of pole surfaces that create a magnetic field which is unchanged according to time. Since the disk rotates, a relatively changing magnetic field passes through the conductive disk causing Eddy currents to be induced inside the disk. These induced Eddy currents produce an opposing magnetic field forcing the rotating disk to slow down by means of consuming mechanical energy. Mathematical analysis of the effects of Eddy currents is almost impossible due to the complexity of both the magnetic problem and geometry. There is no obtained certain relationship which can explain output data in terms of input data since the relation includes too many variables including disk areas, disk thickness, disk radius, speed, etc. In this study, different eddy current brake designs are analysed where all design constraints were kept unchanged apart from conductive disk thickness to determine the effect of change. All mentioned designs are analysed by commercial software using finite element method (FEM). Torque vs. speed, total power dissipation vs. speed characteristics for low, medium and high speed regions and change of critical speed and maximum braking torque according to conductive disk thickness are also obtained.","PeriodicalId":199911,"journal":{"name":"4th International Conference on Power Engineering, Energy and Electrical Drives","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129668237","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, degradation that always happens in the insulation system will reduce the lifespan of the machine. Thus, condition monitoring of the insulation system is highly recommended in order to maintain the reliability and efficiency of the machine during operation. Polarization and Depolarization Current (PDC) measurement is one of the time domain condition monitoring that been acknowledge by the researchers around the globe. This predictive maintenance with the aid of online monitoring provides an indication of the machine's condition. The development of measurement technologies and data analysis techniques using computational methods give an advantage in saving time and improve safety. This paper presents the user panel that had been developed for the application of PDC diagnostic methods. Through this panel the conductivity level based on PDC measurement on the machine insulation system can be analyze and monitored. The developed user-friendly panel enable user to run the recorded PDC data to evaluate the performance of the insulator in term of its conductivity. It was found that the conductivity level of the insulation material is related to its PDC curves. The system developed was found successfully helping user to do analysis on PDC data by giving the PDC pattern and conductivity of the tested insulator.","PeriodicalId":199911,"journal":{"name":"4th International Conference on Power Engineering, Energy and Electrical Drives","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129669294","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 this paper, a medium voltage multilevel converter is considered based on a three-phase cascaded H-bridge (CHB) multilevel converter and multiple string dc-dc converters. Multilevel converters have reduced switching frequency, good power quality with less THD thus reducing filter requirements. The need of several sources on the dc side of the CHB makes this multilevel technology attractive for photovoltaic applications. Moreover, the converter structure is very flexible and modular. The main challenge of this configuration is to handle the power imbalances among the different cells of one phase of the converter as well as among the three phases. A control strategy based on space vector modulation(SVM) to deal with these imbalances is proposed in this paper. Simulation results of a 5-level CHB for a multistring PV system in MATLAB/Simulink are presented to prove the effectiveness of the proposed control method.","PeriodicalId":199911,"journal":{"name":"4th International Conference on Power Engineering, Energy and Electrical Drives","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126897336","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}
