Although TCP/IP-based networks can provide the communication infrastructure for these devices, a severe security issue will present, as these devices are vulnerable to being compromised by cyber-attackers. Use of a disjoint protocol such as DNP3 for SCADA networks provides an effective solution to the security issue. However, DNP3 does not have adequate peer-to-peer networking to support the collaborative computing. This paper proposes an extension protocol layer for DNP3 to facilitate the collaborative computing. This extension offers a routing mechanism that utilizes a variable address structure to create a routing path between communicating devices. The routing path eliminates protocol overhead typically associated with network layers and provides a unique network address for every device in the distribution system. The routing mechanism is interoperable with DNP3- based devices and does not alter the DNP3 specification.","PeriodicalId":196861,"journal":{"name":"2007 IEEE Canada Electrical Power Conference","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130760546","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}

Among different types of wind turbine generators, PM synchronous generators (PMSG) offer better performance due to higher efficiency and less maintenance since they do not have rotor current and could be used without a gear box. In addition, the utilization of a double conversion results in higher flexibility compared with other wind turbine systems. This paper develops the model of a PMSG wind turbine and then simulates short circuits to evaluate the performance of the system during short circuit fault. Since PMSG wind turbine systems use a double conversion converter, this paper develops two methods for controlling the converter, a new protection method for capacitor over voltage is also evaluated in this paper.","PeriodicalId":196861,"journal":{"name":"2007 IEEE Canada Electrical Power Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114157578","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}

A fuel cell vehicle can significantly benefit from being hybridized with an energy storage system (ESS), in terms of vehicle performance, fuel economy, and vehicle cost. A power control strategy is essentially required for FC-HEVs, in order to achieve appropriate power management and regulation among different energy sources and propulsion systems on board the vehicle. Based on this background, this paper aims at reviewing few widely proposed power control strategies developed for FC-HEVs. First, popularly proposed power system configurations for FC-HEVs will be introduced, followed by selectively reviewing and discussing a range of accepted power control strategies for FC-HEVs, from the point of view of critical vehicle performance parameters.","PeriodicalId":196861,"journal":{"name":"2007 IEEE Canada Electrical Power Conference","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134123717","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}
