In the first part of the paper, the experimental field measurement results from a recently rehabilitated 400/220 kV substation belonging to the Romanian Transport and System Operator (TSO) Company are presented. It follows the experimental field measurement results from two 110/20/10 kV electricity distribution substations. The high intensity field zones are highlighted and the highest field value found is compared with the exposure limits given by the actual legislation. In the second part of the paper theoretical field computation methods are approached following two main reasons: to validate the experimental results and to proof their efficiency in evaluating the electromagnetic field values in the neighbourhood of the power devices from complex systems such as the substations. The final conclusions of the study performed and the actions proposed to be taken in practice finish the paper.","PeriodicalId":345557,"journal":{"name":"2008 International Symposium on Power Electronics, Electrical Drives, Automation and Motion","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114923943","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 addition to the very high energy density of methanol, the DMFC is characterized by easy handling and unproblematic refuelling. Direct methanol fuel cells are attractive for various applications, for example as replacements for batteries or accumulators, since DMFC systems permit longer operating times due to the high energy density of methanol. A market analysis was performed to find the best commercial application for the future. The results of this market analysis show that the best potential for systems lies in the material handling sector. Therefore, a DMFC system was designed for a horizontal order picker. In this paper, the system will be described in terms of process engineering and hybridization. For hybridization, the focus is on the used energy storage. The control strategy of the DMFC system was also described.","PeriodicalId":345557,"journal":{"name":"2008 International Symposium on Power Electronics, Electrical Drives, Automation and Motion","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126640264","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 measured impedance curves are heavily influenced by the saturation level of the rotor slot bridges. The saturation phenomena of the closed rotor slots can be divided into mechanical angle-dependent and independent groups. The saturated and the opened rotor slots lead to non-sinusoidal HF-field distribution. The measured curves and the assumptions made are verified by FE calculations and an equivalent magnetic circuit. In the paperpsilas second part a new method for sensorless control is presented. Because of the inimitability of the measured impedance curves, the method is based on the minimum error between the measured curves during the machinepsilas operation and precommissioned reference curves. Operation at standstill, and even at zero-frequency, is possible without any problems.","PeriodicalId":345557,"journal":{"name":"2008 International Symposium on Power Electronics, Electrical Drives, Automation and Motion","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123401007","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}
