It has already been known that switching overvoltages are the most important criteria which the design of insulation of extra high voltage (EHV) systems is based on. The reduction of switching surges is therefore an economic necessity. This paper illustrates switching overvoltages resulted from various switching conditions applied to all the existing 500 kV transmission lines of the Electricity Generating Authority of Thailand (EGAT) system. The study is performed with computer transient simulations using the PSCAD/EMTDC program. Details of the system modeling are outlined. The appropriate representation for the various components such as transmission lines, transformers, equivalent sources, shunt reactors, surge arresters and circuit breakers has been chosen. Switching representing the two most severe causes: line energization and line re-energization due to faults i.e. single phase to ground and three phases to ground are considered. Results are analyzed in this paper.","PeriodicalId":226571,"journal":{"name":"Large Engineering Systems Conference on Power Engineering, 2003","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131538425","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}

Transactions among independent utilities are defined on the basis of price in order to maximize the benefits of interconnection. Each generator in the power system offers a price to change its generation level. The objective function is defined as the minimization of the total expenditure to supply the system's load. The basic formulation and some of the possible extensions of the proposed method are presented in the paper. A modified IEEE 30 bus system is used for comparing the proposed method with more traditional techniques in an interconnected system.","PeriodicalId":226571,"journal":{"name":"Large Engineering Systems Conference on Power Engineering, 2003","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131409007","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}

During the past two decades, research attention has been focused on improving the performance of vertical-axis wind turbines. The paper introduces a new vertical axis wind rotor for low wind speed areas, which uses a convergent nozzle for the amplification of wind speed. Instead of using large central station power plants, these new rotors can be most conveniently built in smaller units appropriate for individual load requirements. The importance of the work is high especially due to the current trend towards distributed or dispersed generation. Another effort has been made to analyse the optimum nozzle dimensions for a better performance of the system.","PeriodicalId":226571,"journal":{"name":"Large Engineering Systems Conference on Power Engineering, 2003","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130213470","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}
