The estimation method is based on synchronous generator corresponding voltage-current vector diagram and parameters of generator, transformer and transmission lines. In addition measurement of the load angle is presented. The estimation results were compared with the measured ones. The estimation method gives satisfactory accuracy for load angles less then 120° el. Although the load angle is a key variable for generator stability, it is rarely used as a variable in excitation control system, because the measurement problems. Hence, this estimation method has a wide area of application in excitation systems for control algorithm and to provide stabile work of synchronous generator in capacitive operating area.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132787628","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 particular we propose a technological solution to overcome both the strong reduction in optical transmittance due to the very high extinction coefficient of metal contacts and, at the same time, the optical scattering induced by the texturization effect induced on α-Si∶H films grown on TCO. The realized waveguides were characterized in terms of propagation losses at 1550nm and surface roughness. The experimental performances have been compared to those obtained through calculations using an optical simulation package. The results are found to be in agreement with the experimental data.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128385480","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}

Dual signal-to-interference ratio (SIR)-based selection diversity system over correlated Rician fading channels in the presence of arbitrary number of correlated Nakagami-m CCIs is studied in this paper. Useful analytical expressions for the probability density function (PDF) and cumulative distribution function (CDF) of SIR at the output of dual selection diversity receiver are derived. These expressions are used to study the outage probability and average bit error probability (ABEP) of the proposed system.
