It helps in transferring energy between two or more circuits through electromagnetic induction. Single phase transformers find applications in domestic appliances because of its simplicity and less cost. They can be used as voltage regulators in television set, as step up and step down transformers in inverters and mobile chargers, respectively. Three phase transformers are used in generation, transmission and distribution of electrical energy. Electromagnetic analysis of the simulated transformer helps in optimizing the transformer design. In this paper, single phase transformer of rating 67kVA 6600/440 V is designed and modeled using Solidworks software. Electromagnetic analysis of the model with normal working condition is done using Electro Magnetics Simulation (EMS) module of the software. AC magnetic study with 50Hz frequency is selected. Parameters like current density, field intensity, and loss density are analyzed. It is observed that results obtained from simulation closely matches with the theoretical values.","PeriodicalId":6552,"journal":{"name":"2015 International Conference on Technological Advancements in Power and Energy (TAP Energy)","volume":"20 1","pages":"427-431"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79530685","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 limitation of electric vehicles paved way for the evolution of hybrid electric vehicles. Among the various known architectures for hybrid electric vehicles, the parallel mild hybrid is expected to be the right candidate to be introduced in a developing country. This is because the size of the electric powertrain in such vehicles shall be relatively smaller compared to the other vehicle architectures and hence shall be less costly compared to the electric vehicle or other hybrid electric vehicle configurations. This paper aims at explaining the procedure of deriving a parallel mild hybrid vehicle equivalent to Tata Safari, a passenger vehicle already available in Indian market. The paper also compares the performance specifications of both vehicles and determines the losses in the proposed vehicle during the normal cruising mode and regenerative modes while traversing a typical Indian urban driving cycle and an Indian highway driving cycle.","PeriodicalId":6552,"journal":{"name":"2015 International Conference on Technological Advancements in Power and Energy (TAP Energy)","volume":"42 1","pages":"506-510"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88883246","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}

Large concentration of single phase non-linear loads will inject harmonics in to the system and create unbalance in the source current. Most of these loads consume more reactive power and thus increases feeder losses and reduces active power flow capability of the system. In this paper, a STATCOM based controller for a three phase system feeding single phase loads is presented. The objectives of the controller in the system is to compensate the inductive loads to obtain nearly unity power factor, balance the source currents by cancelling the effect of unbalanced loads and to filter out the load harmonic currents in order to form a sinusoidal supply current. Single phase synchronous reference frame theory based algorithm is used for generating the reference source currents. A simulation model of the system is developed in MATLAB SIMULINK and tested with linear and non-linear loads under balanced and unbalanced conditions.","PeriodicalId":6552,"journal":{"name":"2015 International Conference on Technological Advancements in Power and Energy (TAP Energy)","volume":"236 1","pages":"333-338"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80349851","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}

Modern nanogrid architectures usually serve to interface both DC as well as AC loads with different kinds of energy resources. This paper proposes a Ćuk-derived hybrid converter (Ćuk-DHC) procured from the conventional Ćuk topology, where the single power electronic switch is replaced with a voltage source inverter bridge network. The resulting converter employs lesser number of switches to produce DC and AC outputs simultaneously. A major advantage of this hybrid converter is that it has immanent shoot-through protection in the inverter stage making it reliable for modern compact smart residential power systems. Moreover, being a derived converter, it holds the advantages that a conventional Ćuk converter possesses. Operating modes and the steady state analysis of the proposed converter have been studied in this paper. A modified unipolar sine pulse width modulation (PWM) technique is used as the control strategy for the operation of the hybrid converter. The characteristics and operation of the proposed converter has been validated through simulation. For improving the output gain factor, a switched inductor cell based modification has been imposed on the hybrid converter to upgrade both dc as well as ac gains and the same has been affirmed via simulation.","PeriodicalId":6552,"journal":{"name":"2015 International Conference on Technological Advancements in Power and Energy (TAP Energy)","volume":"58 1","pages":"387-392"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84280268","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}

Effective management of loop flows and congestion is one of the primary challenges posed to the utilities. To improve grid utilization and relieve congestion, series compensators are incorporated in transmission lines. High cost, sizing, operating region and effort in switching concerns have limited their deployment in these applications. The concept of transformation ratio based series compensation is proposed as a means to eliminate these obstructions. The series capacitors integrated across transformer of appropriate turns' ratio affords the desired power flow control on the transmission system. This materializes due to change in effective line reactance. Cost effective, automated series compensation is experimented on a 2-bus system and the proposed concept is validated.","PeriodicalId":6552,"journal":{"name":"2015 International Conference on Technological Advancements in Power and Energy (TAP Energy)","volume":"18 1","pages":"211-216"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82441829","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}
