When a fault occurs on the transmission line by detecting the traveling waves at substation based on the pattern recognition of the first wavefront that arrives at the location of relay is used to classify whether they are within the reach of the relay using PCA algorithm and by implementing Type D locator i.e. two terminal method in algorithm, the discrimination is verified. The idea is tested for different types of faults and is simulated using MATLAB/Simulink and the performance of the algorithm is reported.","PeriodicalId":145373,"journal":{"name":"2017 International Conference on Power and Embedded Drive Control (ICPEDC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129015697","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 energy density of a battery is high but its power density is less which is opposite in the case of supercapacitor (SC). Thus, combining battery and supercapacitor the battery lifespan is prolonged which makes the system more reliable and efficient. In this paper, the battery and supercapacitor hybrid energy storage system (HESS) model is presented. The optimization of the HESS by reducing the operation costs and investment costs is necessary so that the wind/solar energy are fully utilized. The objective of the optimization is the minimization of operation and capital costs in the complete lifespan considering the constraints. In this paper, nonlinear programming (NLP) is used in General Algebraic Modelling Software (GAMS) to solve the optimization problem. The GAMS which is an effective and simple platform for optimization computations consists of a number of solvers with different algorithms. The CONOPT solver is used for solving the optimization model in this paper. The results obtained henceforth are studied and then compared with the results obtained by optimizing the HESS system with particle swarm optimization (PSO) technique. The results obtained by solving with GAMS are optimized, better and showed lesser computation time.","PeriodicalId":145373,"journal":{"name":"2017 International Conference on Power and Embedded Drive Control (ICPEDC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129170441","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 rectifier topology is capable of providing a dc output voltage that is higher than the ac source voltage with improved power factor. The topology is compatible with the hysteresis current control (HCC) technique. It has the capacity to provide almost unity power factor with low current distortion at the ac utility and a fairly well regulated voltage with low ripple content at the dc output. In this paper, the HCC technique is implemented in the single-phase Vienna rectifier topologies with the ac source at two different voltages and frequencies, and the power quality indices have been estimated using MATLAB simulations. The simulation results suggest, the topologies with HCC provide ac to dc power conversion in compliance with contemporary power quality norms.","PeriodicalId":145373,"journal":{"name":"2017 International Conference on Power and Embedded Drive Control (ICPEDC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130623660","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 this paper, an Artificial Neural Network (ANN) model has been created for prediction of ID fan power consumption. Operational data from fifty number of steam generators has been collected.
