With the selected road model, for the road without middle line, the road recognition algorithm is composed of two modules. The road boundaries detection module is used to get the information about road boundaries when vehicle just runs. Meanwhile the boundaries following module is started to predict the position of road edge when vehicle runs stably with the prediction knowledge. The road boundaries detection module amalgamates two kinds of information together and uses the adjacency of them in the space to get the exact information of road boundaries. The arithmetic is effective and precise.","PeriodicalId":309894,"journal":{"name":"2008 3rd IEEE Conference on Industrial Electronics and Applications","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124393782","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}

Superconducting fault current limiters (SFCLs) can limit the prospective short-circuit currents to lower levels, so that the underrated switchgears can be operated safely. Due to its simple structure and lower price, the resistive type superconducting fault current limiter (RSFCL) is being used widely in practical experiences. Since RSFCLs are installed to provide high levels of power quality for customers with sensitive loads, it is necessary to investigate their harmonic generation. In this paper, harmonic generation of a RSFCL installed in a distribution system is investigated considering the current total harmonic distortion (THD). Then a method is presented for determining the optimum high temperature superconductor (HTS) volume considering its harmonics generation. It is concluded that the THD reduces as the HTS element volume decreases. Also, since decrease in HTS element volume leads to decrease in limiting behavior of the RSFCL, an optimization should be achieved between the limiting behavior and the current THD level. This optimization results in the optimum volume determination of the HTS element.","PeriodicalId":309894,"journal":{"name":"2008 3rd IEEE Conference on Industrial Electronics and Applications","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124582707","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}

As such, the performance of this equipment operating in unprotected ac supply systems reflects the behavior of the SMPS to the voltage surges and sags that are endemic to power systems not protected by UPS. One purpose for this paper is to analyze the operation of SMPS during line voltage sags over and above merely observing the discharge of the dc link capacitor. A further purpose is to show that the tolerance of an SMPS to line-voltage sags can be improved by: (1) using a larger dc capacitor; (2) operating at less than the power rating; and (3) using power factor correction. Inrush current control circuits must be designed to operate effectively for line voltage sags of all predictable depths and time durations. Moreover, voltage disturbance plots of events do not indicate SMPS failures for each event outside the ITI limits. A percentage of SMPS will be operating at part load and not fail.","PeriodicalId":309894,"journal":{"name":"2008 3rd IEEE Conference on Industrial Electronics and Applications","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114796429","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}

Benefits of these new power devices are now more clearly identified and applications were depicted where the use of these new components, in particular Schottky barrier diodes available from Infineon and Cree, can be a technical and commercial access. For a further market penetration, new generations of diodes as well as powerful switching devices are released recently resp. ready to commercialization. Especially upcoming markets for high voltage power devices offering not only high power densities, but energy saving as well push these developments. Supported by the improvements in base material quality and size, SiC power devices are believed to be on the hop to a next important step regarding its propagation in a broader range of applications. The paper will sketch these recent developments and will show how the improved performance can provide new perspectives in conventional systems as well as new solutions.","PeriodicalId":309894,"journal":{"name":"2008 3rd IEEE Conference on Industrial Electronics and Applications","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114563279","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 proposed method, additional phase shift is introduced to help stimulating the islanding detection function and the algorithm is simplified as well. When the utility grid is disconnected, the algorithm keeps the frequency of the converter output voltage deviating until the frequency protection relay is triggered. The working principle of the method is introduced and the guidance of parameters selection is also provided. The islanding detection performance is evaluated through theoretical analysis, digital simulation and experiment.
