For this reason, various equipments based on the power electronics have been developed under the name of Flexible Alternating Current Transmission Systems (FACTS) devices; which are used in the last couple of years. Among all the facts devices Unified Power Flow Controller (UPFC) is the most versatile one in regard to control the power flow and to improve the transient stability of a system. The modelling of the controller plays a major role in the performance of the UPFC. The performance of UPFC for different mode of operation using PI controller is being studied. In this paper, a detailed comparative analysis is done, by taking performance criteria of UPFC controller into consideration, for optimal tuning of PI controller through various optimization techniques. By taking the settling time as the reference the performance is compared with Genetic Algorithm (GA), Particle Swarm Optimization (PSO) and Cuckoo Search Optimization (CSO) which are so called population optimisation techniques, used for optimal tuning of PI controller. The UPFC is modelled in our user friendly software MATLAB/M-file environment.","PeriodicalId":290479,"journal":{"name":"2013 IEEE 1st International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126852423","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}

For a reliable design of power system the proper insulation coordination among the power system components must be achieved. Insulation coordination is generally done by considering the behavior of insulation under standard lightning and switching impulses. In practice the system components might be stressed with the overvoltages of non-standard impulses like VFTO and oscillatory impulses. This necessitates the study of non-standard impulses on insulating materials. Transformers are considered as the major equipment in power system, which requires the detailed analysis on v-t characteristics of its insulation. In this paper an attempt has been made to analyze the breakdown characteristics of Oil Impregnated Paper (OIP) for different impulse waveshapes with varying front times from tens of nanoseconds to few microseconds and CIGRE representative waveforms. The v-t characteristics are mathematically modelled using Hyperbolic model. Thus developed models are used for predicting the v-t characteristics for any type of overvoltages of the above mentioned categories and compared with the experimental results.","PeriodicalId":290479,"journal":{"name":"2013 IEEE 1st International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128510200","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}

This paper presents a novel method for face recognition by fusing original and corresponding diagonal images. Two ways of image fusion technique have been performed here. Firstly, we generate diagonal face image from original face image and append original image with the diagonal image horizontally side by side. Secondly, original face image and the corresponding diagonal face image are appended vertically to get two sets of fused image matrices. The G-2DFLD method is applied on both of these large fused images for extraction of discriminant features, which integrate the underlying discriminant information along the horizontal, vertical and diagonal directions. This extracted feature matrices are applied on Radial Basis Function-Neural Networks (RBF-NN) for classification and recognition. Experiments on the AT&T face database (formally known as ORL database) indicate the superiority of the proposed method as compared to some of the conventional methods.","PeriodicalId":290479,"journal":{"name":"2013 IEEE 1st International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116888728","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}
