In order to propel high frequency power distribution into larger power grade, an effective ac arc protection scheme is significant for safety and reliability. However, almost all of the studies of arc fault are focused on dc or low frequency ac (LFAC). This paper presents protection scheme and examines electrical characteristics for high frequency arc fault. Meanwhile, high frequency breaker is examined with ZCS feature, and residual current devices (RCD) design is explored for high frequency power distribution as well. First, the location of arc fault detector (AFD) and interrupting devices (ID) is studied from system level; and the single phase arc grounding fault is analyzed for high frequency sinusoidal waveforms. Second, zero-current-switching (ZCS) feature of high frequency breaker is discussed from monitor circuit and breaker circuit. Third, trigger deficiency of high frequency RCD is demonstrated and corresponding solution is examined. Lastly, the simulation results further testify the effectiveness of theoretical analysis.","PeriodicalId":198357,"journal":{"name":"2015 6th International Conference on Power Electronics Systems and Applications (PESA)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124011207","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}

Two kinds of parallel programming models (OpenMP shared-memory and MPI message-passing) are widely used on the SMP (Symmetric Multi-Processors) cluster. By comparing different programming paradigms for parallelization on the nodes of a SMP cluster, we obtain a parallel computing model that shows high performance. When parallel communication is low, using MPI programming purely will be more efficient. Otherwise, the hybrid MPI/OpenMP parallel programming model can be used to achieve better results. The main characteristic of the hybrid programming model is that the whole project is divided into segments according to the hierarchical structure of the task being executed, and this division is based on the principle of system load balance. Task level process adopts MPI for inter-SMP nodes communication, and uses OpenMP for intra-SMP node parallelization inside each processor. Experimental results show that this hybrid parallel computing model yields high performance and works very effectively.","PeriodicalId":198357,"journal":{"name":"2015 6th International Conference on Power Electronics Systems and Applications (PESA)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122808052","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}

Based on the rigid space envelope limits and performance specifications required by the vehicle, four candidate versions of a FSCW PMSM have been determined by initial machine sizing analysis. All versions share the same rotor outer diameter, rotor back iron thickness, permanent magnet thickness, air gap length, and magnet pole arc width ratio. A window-zoom-in response surface method based on two-dimensional parametric finite element analysis is proposed for comprehensive electromagnetic optimization for maximum torque density. Additionally, the machine losses at rated torque output including copper joule loss, rotor eddy current loss, and stator core loss maintain the same in all the candidates. It is found that significant correlation exists between stator slot depth and active axial length in the optimal outer-rotor PMSMs. Finally, the performance characteristics of the four optimal machines are comprehensively evaluated and compared to confirm the best candidate, and its utility for the vehicle's mission.","PeriodicalId":198357,"journal":{"name":"2015 6th International Conference on Power Electronics Systems and Applications (PESA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130610179","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}
