Considerable effort is put into the selection of the appropriate battery with specific regard to the battery's state of charge (SOC) and battery reserve time during the discharge profile for the various loading conditions expected. The new enhanced model has increased accuracy; it includes voltage, current, and power monitoring functions and further permits modeling of the cycle-by-cycle charge/discharge characteristics which is imperative for regenerative applications. Furthermore, the operating features of this enhanced battery model are demonstrated for two regenerative simulations. The new battery model is interfaced to a full-bridge, bi-directional, PWM controller with bi-polar voltage switching. The load is a DC motor model with motor parameters such as load torque, viscous torque and inertia. The power converter/DC motor system presents bidirectional power flow to the battery model. The purpose of the first simulation is to demonstrate real-world operation of the battery model including regeneration. A second simulation has an ultra-capacitor bank connected across the battery terminals to compare the battery model charge/discharge parameters such as voltage, current and power when the ultra-capacitor bank is absent and when present in the system","PeriodicalId":356699,"journal":{"name":"INTELEC 06 - Twenty-Eighth International Telecommunications Energy Conference","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125148259","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 PLC must overcome the harsh and noisy environments inherent in PLC channels. HomePlug 1.0 is the current PLC standard in North America. The physical layer of HomePlug 1.0 employs orthogonal frequency division multiplexing (OFDM) as well as concatenated Reed-Solomon and convolutional coding. Aiming to obtain higher PLC throughput, we investigate the performance of OFDM with low-density parity-check (LDPC) codes and compare the proposed scheme with HomePlug 1.0 ROBO mode. In our simulations, the PLC channel is modeled by multipath fading, with Middleton's Class A noise (AWCN) model simulating the worst-case impulsive noise. We apply clipping to lessen the impact of impulsive noise. A simple but effective method is devised to estimate the variance of the clipped noise for LDPC decoding. In comparison with ROBO mode, the proposed scheme offers improved performance and lower computational complexity per decoded bit. Our scheme provides increased throughput by dispensing with ROBO mode's repetitive transmission of information to gain time diversity","PeriodicalId":356699,"journal":{"name":"INTELEC 06 - Twenty-Eighth International Telecommunications Energy Conference","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124956327","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}

Fast-charge is very interesting in different applications (communications systems, electric vehicles, low-earth-orbit spacecrafts) in order to minimizing charge time. The problem is that high currents involved in fast-charge process affect battery behavior modifying parameters as battery charge acceptance. Moreover, battery temperature increase and gasses production related to overcharging make necessary to detect accurately the end of fast-charge to avoid battery damage. Limited information about results of charging process at different charging rates (i.e. time reduction versus charge efficiency) makes difficult to select the optimum rate in each specific application. The lack of information is more problematic in NiMH batteries due to they can not support as well as NiCd batteries extreme working conditions. For these reasons, an intensive study about NiCd and NiMH battery behavior under different charging rates was developed. In this paper, the effects of fast-charging on medium/high capacity NiCd and NiMH batteries are shown. In this way, conclusions about the application range of fast-charging in both technologies are drawn","PeriodicalId":356699,"journal":{"name":"INTELEC 06 - Twenty-Eighth International Telecommunications Energy Conference","volume":"213 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132812835","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}

(USI) to provide engineering, furnishing and installation services (EF&I) to the telecommunications industry. The '96 Telco Act triggered significant speculation by venture capitalists to profit from the entry of competition for the Regional Bell Operating Companies (RBOCs). In addition, The '96 Telco Act facilitated spending by start-ups to provide telecommunications services by co-locating with the RBOCs. The '96 Telco Act forced RBOCs to lease their private facilities to co-location customers below cost. USI supported Competitive Local Exchange Carriers (CLEC). When The '96 Telco Act was passed, the industry witnessed the rise of RBOCs, and Universal Solutions was in the enviable position to support all of them. Shortly thereafter, USI landed contracts with all the major CLECs and then the all of RBOCs [end-users]. The '96 Telco Act moved RBOCs - which enjoyed operating as a local region monopoly to compete with cable companies, co-location customers and other RBOCs nationwide. The competition resulted in mass consolidation of telecommunication providers and the number of RBOCs quickly shrunk from eight to four","PeriodicalId":356699,"journal":{"name":"INTELEC 06 - Twenty-Eighth International Telecommunications Energy Conference","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132884756","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}
