Superconducting motor is one of the electrical devices that attracted the attention of engineers and researchers from the universities and industries due to its distinctive energy efficiency. This paper addresses the performance of superconducting-wound electric motor when compared with conventional copper-wound electric motor. DC synchronous single-phase series motor has been chosen as the base for development of both motors. Two prototypes of electric motor fabricated using conventional copper coils and superconducting coils were developed with similar motor type, design, dimensions, and features. The superconducting motor coils were wound using the drastically innovative Bi-2223 (DI-BSCCO) Type H wires developed by the Sumitomo Electric Industries Limited, Japan. A finite element analysis was also performed to get a clear view on flux plots of the magnetic induction. Features of the superconducting motor and the special coil frame designed to protect the superconducting wire was also presented in this paper. In addition, the torque performances for both types of motor were measured. The superconducting electric motor was found to consume lower power to produce the same output compared with the conventional copper-wound motor.","PeriodicalId":211736,"journal":{"name":"2009 3rd International Conference on Energy and Environment (ICEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131447581","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}

When load increases, the apparent impedance decreases accordingly depending on the nature of load, similar instances can be observed during short circuit event [1, 2]. In addition, the system may also experience voltage instability originating from high power flow through the transmission line during fault and line outage condition. Hence, the ability for the system to quickly indicate possible voltage instability via fast voltage indicator is important in mitigating voltage instability from being further aggravated. Undesirable disconnection of transmission lines should also be avoided during voltage instability, while load encroachment possibilities into protective zone may cause unnecessary line isolation, which would result in cascading tripping [3, 4]. This paper presents the correlation between the apparent impedance calculated from different contingency scenario and the derived voltage indicator applied to the IEEE 30 Bus Test System.","PeriodicalId":211736,"journal":{"name":"2009 3rd International Conference on Energy and Environment (ICEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130230130","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 PU/PIR duct is new and fast growing integrated material of aluminum and insulation material compacted together to achieve thinner overall thickness as compared to conventional steel ducting with insulation wrapped around it. As compare with sheet metal duct fittings, PU/PIR duct fitting has numerous notches inside the duct fittings. These notches (or grooves) are necessary in the fabrication of fitting components because PU/PIR panel cannot be bent without these notches as the panel is very thick (20mm). On the other hand, sheet metal does not need these notches to be bent since it is thin (0.5∼1.2mm). This paper investigates the effect on friction loss of duct fitting with some of these notches in the air stream. A simple 90 degree elbow of 300mm×300mm duct dimension is simulated for comparison. The PU/PIR sheet metal design compared to PU/PIR duct with notch has slight difference in terms of pressure loss. It can be concluded that notches in PU/PIR duct design has negligible effect on the pressure loss but it has numerous advantages compared to conventional HVAC duct fabrication design. The detail results are discussed.","PeriodicalId":211736,"journal":{"name":"2009 3rd International Conference on Energy and Environment (ICEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114500011","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 study on the air-conditioned buildings was carried out in UNITEN and for the non air-conditioned buildings in two schools, which is a primary and secondary school, and in a public waiting area in a health clinic in Johor Bahru, located in the southern region of Malaysia. The non air-conditioned buildings were mechanically ventilated by fans. The studies were made in different days from morning until noon as to get variation of temperatures, collecting a full set of objective physical measurements and subjective assessments through questionnaires. The measured environmental parameters were air temperature, relative humidity and air velocity. The subjective responses concern the judgment of the respondents about the thermal environment at the moment of measurements. The results obtained showed that majority of the respondents found that their indoor thermal conditions acceptable even though most of the thermal sensation votes (TSV) exceeded those specified by ASHRAE Standard 55 and the environmental assessments exceeded the standard. The neutral temperature and comfort range were obtained through linear regression analysis of TSV and in the Fanger's PMV model. From the subjective assessment, it was found that the occupants can accept the thermal range beyond the ASHRAE comfort zone. The neutral temperature of 24.4°C and 28.4°C for air-conditioned and non air-conditioned buildings respectively, were obtained by regression analysis of TSV on operative temperature. The acceptable range of temperature obtained by regression analysis of TSV were 23.1°C to 25.6°C for air-conditioned buildings and 26.0°C to 30.7°C for non air-conditioned buildings.","PeriodicalId":211736,"journal":{"name":"2009 3rd International Conference on Energy and Environment (ICEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128470684","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}
