The change over to three-phase squirrel-cage AC traction motor in electric locomotives, on inverter supply, made the traction drive most economical with high kW/kg ratio, thereby also reducing the un-sprung mass on the axle. In AC traction motor, alternative aluminium alloy rotor bars have been proposed to achieve better performance, light weight, cost reduction, and to meet the scarcity of copper to come in future. Design of rotor plays a vital role in development of torque on motor shaft. The important parameter in design of AC traction motor under inverter supply is the consideration of harmonics generated by it. In this paper, back propagation artificial neural network technique has been adopted to optimize the output design parameters of the AC traction motor rotor with aluminium alloy bars, keeping the stator design un changed. The comparison of AC traction motor with copper bars vis-vis aluminium alloy rotor bars in respect of torque developed and efficiency have been dealt in this study which present a good alternative approach in AC traction motor design.","PeriodicalId":107016,"journal":{"name":"2008 Joint International Conference on Power System Technology and IEEE Power India Conference","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127055369","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 ability of market participants to exercise market power in the wholesale market is questioned at any time wholesale electricity spot prices are perceived to rise beyond the perceived cost of production for electricity. In addition to the potential exercise of market power through strategic bidding, opportunities for exploitation of market power may arise from the dispatch and pricing methodologies used in the New Zealand market. Congestion based pricing in an LMP dispatched market can also provide opportunities for exercising market power particularly when combined with the effects of generation portfolios and locational dispersion. The purpose of this paper is to i) Briefly review international experience of market power issues; ii) Examine opportunities for exercising market power in the New Zealand wholesale market environment; iii) Describe some methods available for measuring market power and review their characteristics; iv) Form an opinion as to whether these tools for measuring Market power are appropriate to the New Zealand Wholesale Electricity Market. Where not appropriate, to outline the characteristics of suitable measures.","PeriodicalId":107016,"journal":{"name":"2008 Joint International Conference on Power System Technology and IEEE Power India Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129163532","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 primary current waveform causes primarily differential mode emission currents to circulate between the AC mains and the power supply input. It can also create common mode emissions due to radiated magnetic fields if the current path defined by the PC board layout encircles a large physical area. The drain voltage, diode voltage and secondary current waveforms are mainly responsible for the generation of common mode emission currents. Controlling EMI in SMPS requires attentions to following areas: 1. Differential mode filtering 2. Common mode filtering 3. Power cord damping 4. Transformer construction This paper addresses the concept of EMI signature in SMPS and presents conceptual techniques for EMI suppression. Differential mode filter analysis and common mode filter analysis are discussed in detail and an effective high frequency circuit model of the differential mode filter is obtained. Important aspects of power cord damping and transformer construction are also briefly covered. This paper is intended to be an efficient helping tool for the EMI filter designers.","PeriodicalId":107016,"journal":{"name":"2008 Joint International Conference on Power System Technology and IEEE Power India Conference","volume":"120 23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126315528","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}
