The switching table base DTC(ST- DTC) is implemented to the dynamic machine model for 2 level and 3-level voltage source inverter. Out of 27 switching vectors of 3-level inverter, 12 active vectors are used for simulation of DTC with 12 sectors. For reduction of torque ripple a five level torque comparator is proposed. A comparison study of DTC using two and three-level inverter shows that the settling time during step rise and step fall are nearly equal but there is a significant improvement in torque ripple reduction with three-level inverter.","PeriodicalId":145373,"journal":{"name":"2017 International Conference on Power and Embedded Drive Control (ICPEDC)","volume":"111 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":"117192119","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 practice, utility of switching device is increased in industrial as well as in domestic applications. Non-linearity causes adverse effects on system efficiency, utility of the power supply, power factor, etc. As reduction in power factor increases reactive power which does not have any contribution in energy transfer so its compensation is needed. So efforts are made to upgrade power quality, concept of Filter is in demand. In contrast to passive filter, active filters are popular due to its smaller size and weight. In this paper, work is done on shunt active power filter (SAPF) using P-Q theory for current harmonic mitigation and reactive power compensation. Here the simulation as well as its parameters, with or without active filter is well presented. We commence the paper with power quality issues then better understanding of PQ theory, simulation circuits, results, comparison and finally ended with conclusion. An effort is made to achieve THD value of source current below 5% to meet the required IEEE standards.","PeriodicalId":145373,"journal":{"name":"2017 International Conference on Power and Embedded Drive Control (ICPEDC)","volume":"115 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":"121839613","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}

Proposed quasi - Y source converter has many advantages of available continuous input current, improved boost ratio and simple topology. It draws continuous current from the source which is required for many renewable sources. The existence of two built-in DC-current-blocking capacitors connected in series with transformer windings prevents the transformer core from saturation. The quasi -Y source converter gives high voltage gain even for small duty cycle. To protect under/over voltage incremental conductance algorithm has been proposed. The system is designed using MATLAB software and its results were discussed.","PeriodicalId":145373,"journal":{"name":"2017 International Conference on Power and Embedded Drive Control (ICPEDC)","volume":"13 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":"128622953","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 deals with wavelet transform based transmission line fault classification and utilizes differential protection scheme for to locate the fault as well as to overcome the performance limit of differential protection transmission lines. The tripping action mainly depends on the current and flux waveforms obtained under fault conditions at two ends of relay location. Wavelet analysis is added as mathematical tool for pattern recognition and feature extraction and to classify the type of fault occurring on the transmission line. The continuous approximation of the Mexican hat as a mother wavelet and coefficients like 32nd and 64th are used to extract frequency information and detect the faulted phase selection. In current differential protective relay system CT saturation problem affect the faithful performance. So with the problem of mal-operation it causes differential protection system. The three phase transmission line currents of two ends are used as input signals at relay location using communication links. Simulation is carried out in Matlab/Simulink which confirms the security and sensitivity of the proposed scheme.","PeriodicalId":145373,"journal":{"name":"2017 International Conference on Power and Embedded Drive Control (ICPEDC)","volume":"11 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":"114349444","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}

Since Maglev is one of the most nonlinear and unstable system, which has to be linearized at an equilibrium point. So for obtaining a linearized transfer function model, local linearization around that equilibrium point (−1.5V) has been performed. In this article, the integral-tilted derivative (I-TD) controller design has been imposed for the Maglev system and its execution is contrasted with conventional tilted integral derivative (TID) controller. In this paper, parameters of TID controller have been tuned through particle swarm optimization (PSO) and those optimized values have been implemented for I-TD controller. The performance of TID and I-TD controller is compared and investigated. The results show the predominance of I-TD controller over TID controller regarding peak overshoot, phase and gain margin. The settling time remains practically unchanged in both the cases.","PeriodicalId":145373,"journal":{"name":"2017 International Conference on Power and Embedded Drive Control (ICPEDC)","volume":"28 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":"132639923","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}
