Assessment of long term reliability and performance of LED arrays is a testing exercise but it is also vital for successful acceptance of Solid State Lighting (SSL) systems. The objective of this work is to analyze IESNA LM-80 test data obtained from the LED manufacturers to study how failure is accelerated by stress and fit an acceleration model to the data. This acceleration model can be used to accurately project the reliability of the LED arrays under normal operating conditions. The methodology was to apply statistical analysis to LM-80 test data and obtain accelerated models for life-stress relationships and life-time distributions. The Arrhenius-Weibull, Generalised Eyring-Weibull and Inverse Power-Weibull models were obtained and were compared for their effectiveness in to predicting the reliability of LED arrays.","PeriodicalId":213443,"journal":{"name":"2012 International Conference on Emerging Trends in Electrical Engineering and Energy Management (ICETEEEM)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114999362","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}

The proposed paper work is to evolve a simple and effective method for an optimum generation dispatch to minimize the fuel cost and emission of power networks. This paper presents a Chaotic Self Adaptive Particle Swarm Optimization (CSAPSO) algorithm to solve DEED problem. Many non-linear characteristics of the generator such as value point effect, non smooth cost functions of fuel and emission and ramp rate limits are considered in this proposed method. The cost function of the generator exhibits the non convex characteristics, as the valve point effects are modeled and imposed as rectified sinusoid components. The velocity, which is popularly known as sensitive parameter of CSAPSO is adjusted dynamically in order to increase its precision. A chaotic local search operator is introduced in the proposed algorithm to avoid premature convergence. The effectiveness of the proposed optimization is verified in simulation studies using MAT LAB software. In this proposed work, fuel cost and emission are treated as competing objectives. The applicability and high feasibility of the proposed method is validated on 10 unit test systems. Results of the application of the proposed method are presented in this reported work.","PeriodicalId":213443,"journal":{"name":"2012 International Conference on Emerging Trends in Electrical Engineering and Energy Management (ICETEEEM)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114409542","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}

According to IEC standard, the power quality is determined from the performance of wind generators. In this paper using a FACTS controller device the power quality enhanced when the wind generators are connected to the grid system. The power quality becomes an issue when wind generators are connected to the grid, due to the interaction between the grid and the wind turbines. The main impact on the grid by the wind generators, regarding power quality, is related to voltage sag, reactive power, harmonics, power peaks and flickers. The power quality problem arises when the wind generators are equipped with the grid, can be improved by connecting a FACTS controller at a point of common coupling. In this paper, UPFC (UNIFIED POWER FLOW CONTROLLER) control scheme for the wind generators connected grid is used to improve the power quality using MATLAB/SIMULINK in power system block set. Also this UPFC control system that includes both the shunt converter and the series converter has been simulated. In this proposed model, the real and reactive power compensation is the main concern.","PeriodicalId":213443,"journal":{"name":"2012 International Conference on Emerging Trends in Electrical Engineering and Energy Management (ICETEEEM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130765130","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}
