In this paper analysis results of a combination the UPQC with a superconducting fault current limiter (SFCL) are presented. SFCL aids on reduction in VA rating of the UPQC with limiting the excessive current in the event of fault. The combination of electrical and thermal model of a designed resistive type SFCL is defined as a component in PSCAD/EMTDC simulations. The proposed scheme can compensate voltage sag and current harmonics at the point of common coupling (PCC) on power distribution systems. Through the results of several analyses and simulations carried out by PSCAD/EMTDC, this demonstrates the signification effect of the control by SFCL on rating reduction of the UPQC.","PeriodicalId":104998,"journal":{"name":"2010 1st Power Electronic & Drive Systems & Technologies Conference (PEDSTC)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132261731","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 nature of the system necessitates that the stator flux linkage amplitude is employed as the loss minimization control variable. Thus, the optimal stator flux linkage is determined in a way that the total electrical loss is minimized. Then the optimal flux is considered as the reference flux.

A Z-source inverter (ZSI) is controlled to extract the maximum power from PV array and supplies the BLDC motor instantaneously. The BLDC motor is driven with variable reference speed dictated from instant maximum PV power by a hysteresis current control loop. Despite the conventional PV water pumping systems, employing a two stages converter, the proposed system enjoys one stage power conversion. Therefore, less number of power switches, less switching losses and lower cost are obtained. By proper designing of control system parameters and maximum power point tracking (MPPT) method for PV array, good steady state and transient performances have been achieved in response to different operation conditions for PV array. Sensorless drive with low torque ripple is provided for the BLDC motor. The system was simulated by PSCAD/EMTDC software for a PV array of 1 kW.","PeriodicalId":104998,"journal":{"name":"2010 1st Power Electronic & Drive Systems & Technologies Conference (PEDSTC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126890855","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 proposed method is based on global optimization for energy management system of a conventional parallel HEV. A rule based fuzzy control strategy is considered for optimization of the system. The fuzzy membership function boundaries are kept constant and the fuzzy rule table is optimized by using genetic algorithm for different types of cycles. The results of the proposed optimization method suggest that fixing the internal combustion engine (ICE) torque constant is prior to keeping the state of charge (SOC) of the batteries constant. It confirms that the electric machine should provide dynamic power of the load and static power should be supplied by the ICE.","PeriodicalId":104998,"journal":{"name":"2010 1st Power Electronic & Drive Systems & Technologies Conference (PEDSTC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121119461","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 example a balanced three phase induction motor can be modeled as an equivalent two phase induction motor (The dq Model). In the same way an unbalanced induction motor can be modeled as an unbalanced two phase induction motor. This paper shows this concept by modeling a faulty induction motor with one of its three feeding phases, open. Moreover the paper shows that the speed control of this faulty motor can be performed by a few modifications in the conventional vector control. This new vector control is suitable for unbalanced induction motors such as the single phase induction motor with unequal main and auxiliary windings. Computer simulation shows the good performance of the proposed method.","PeriodicalId":104998,"journal":{"name":"2010 1st Power Electronic & Drive Systems & Technologies Conference (PEDSTC)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128047129","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}

One of the coupling windings from each phase is in series with that of the other phase and the set of these two windings is reversely paralleled with the secondary winding of the third phase. Under unbalanced condition, the unbalanced current flows through the coupling and secondary windings that each winding is fed from primary by using a separate phase. In this way, part of excess current of one phase is transferred to the other phases. In this paper based on the original load-balancing transformer, two new load-balancing transformers are presented.

A thermal model is proposed where the motor is divided geometrically into a number of lumped components, with interconnections to neighboring components through a linear mesh of thermal impedances. The lumped parameters are derived from entirely dimensional information, the thermal properties of the materials used, and constant heat transfer coefficients. Arrhenius chart is then used to estimate motor insulation remaining life. The proposed approach is used to determine the effect of supply harmonics and voltage unbalances on the useful life of a three phase induction motor and also validated by experimental results.","PeriodicalId":104998,"journal":{"name":"2010 1st Power Electronic & Drive Systems & Technologies Conference (PEDSTC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130723501","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}
