In order to reduce the size of the alternator, an approach for accommodating both excitation windings and permanent magnets in the same rotor core of hybrid excitation alternator is also proposed in the literature. But the output voltage waveform of proposed HEA with one rotor in the literature has higher harmonic content. Hence in order to improve the quality of output voltage waveform, a non uniform air gap hybrid excitation alternator (NUAG-HEA) is proposed in this paper.

This enables ECU software development, calibration and testing in closed loop without the actual vehicle. Using Hardware in Loop (HiL) simulation, the development of control software can be carried out before the real hardware implementation of the vehicle. This method reduces development cost by reducing development time, risk factor and eliminating the use of expensive destructive test systems. This paper discusses HiL Simulation and Rapid Controller Prototyping of EV/HEV Systems by making use of a multi-core xEV real time Simulator. xEV Real time Simulator is a cost effective yet powerful solution for real time simulation which utilizes MATLAB for offline desktop simulation and C code generation. By making use of advancement in processor platforms such as multi-core processors, the real time capability of simulator is enhanced.","PeriodicalId":312418,"journal":{"name":"2017 IEEE Transportation Electrification Conference (ITEC-India)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121779674","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}

Two 2250HP-rated induction motor drives controlled via indirect field oriented control are simulated. Load sharing with different configurations is studied to analyze the impact of individual drive loads on the multi-drive system efficiency. Motor losses, Inverter losses and propeller losses are accounted for in efficiency calculations. For each load torque shared, the individual drive efficiency is calculated to determine which load sharing scheme provides maximum system efficiency. The approach for load sharing and system efficiency maximization is applicable to ship propulsion motor drives for maximum efficiency beyond rated load torques, and to other multi-drive systems.","PeriodicalId":312418,"journal":{"name":"2017 IEEE Transportation Electrification Conference (ITEC-India)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127191935","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}

Vehicles are essential in daily transportation, and an increasing effort is being done to replace the pollutant combustion engines by plug-in hybrid electric vehicles (PHEVs). Better utilization of such potential depends on the optimal scheduling of charging and discharging PHEVs. Therefore, charging and discharging of PHEVs must be scheduled intelligently to prevent overloading of the network at peak hours, take advantages of off peak charging benefits and delaying any load shedding. In this paper presents a novel approach for solve the unit commitment problem of thermal units integrated with PHEVs in an electrical power system. An IEEE 10-unit test system is employed to investigate the impacts of PHEVs on generation scheduling and cost. The results obtained from simulation analysis show a significant techno-economic saving.","PeriodicalId":312418,"journal":{"name":"2017 IEEE Transportation Electrification Conference (ITEC-India)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121261314","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}

Ambient temperature is a significant factor that influences the accuracy of SOC estimation, hence electrochemical combined model dependents of tempera­ture was utilized for simulating the dynamic behavior of battery in BMS. Unknown parameters of the battery model are iden­tified using the least square algorithm for Dynamic Stress Test (DST), validation of estimation is conducted for Federal Urban Driving Schedule (FUDS) and concluded that the error between predicated terminal voltage form model and voltage from DST profile was less than 0.08V for defined conditions. Then, for SOC estimation, recursive Bayesian estimation method based Extended Kalman Filtering (EKF), and Sigma-Point Kalman Filtering (SPKF) approaches were adopted. To quantify the performance of the estimators, Root Mean Square Error (RMSE) and execution time at different temperature were evaluated. The evaluation results indicate that maximum error in case of EKF is 2.43% whereas for SPKF is 1.2% and maximum execution time taken by EKF is 3.57 sec whereas for SPKF is 4.53 sec. The results reported that SPKF provides accurate and robust SOC estimation in compared EKF and could be efficiently applied in BMS for BEVS.","PeriodicalId":312418,"journal":{"name":"2017 IEEE Transportation Electrification Conference (ITEC-India)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125364941","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}

An H-bridge is used as a reverse voltage block (RVB) to convert into bipolar voltage levels including zero level. The level of voltage can be increased by increasing the number of HBCs in LGB.

At input end of the proposed drive, a thirty-six pulse AC-DC converter is used to limit the utility current harmonics to acceptable level as specified in IEEE-519 standard. A 5-level T-type multilevel inverter is used at the drive end to improve the steady state, dynamic and power quality performances of VCIMD. To avoid voltage balancing problem at the input of a T-type inverter, the isolated DC supplies are used. These isolated supplies are derived from a delta-polygon configured phase shifting transformer followed by six pulse diode bridge rectifiers (DBRs). In order to control a T-type inverter and an induction motor, the simple phase disposition (PD) sinusoidal pulse width modulation (SPWM) and the indirect vector control are used, respectively. The proposed drive is examined under all possible operations of an induction motor. The proposed thirty-six pulse AC-DC converter fed 5-level T-type inverter based VCIMD is modelled and its performance is simulated in Simulink/MATLAB environment to demonstrate its effectiveness for the medium and high rating applications.","PeriodicalId":312418,"journal":{"name":"2017 IEEE Transportation Electrification Conference (ITEC-India)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122684443","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}
