The temperature difference between the upper convective zone (UCZ) and lower convective zone (LCZ) of a SGSP can be in the range of 40°C - 60°C. This temperature difference can be used to power thermoelectric generators (TEG) for electricity production. This paper present results of a TEG system designed to be powered by the hot and cold water from the SGSP. The system is capable of producing electricity even on cloudy days or at night as the SGSP acts as a thermal storage system. The results obtained have indicated significant prospects of such system to generate power from a low grade heat for remote area power supply.","PeriodicalId":135966,"journal":{"name":"2012 IEEE International Conference on Power and Energy (PECon)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123871860","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 five-phase induction motor is supplied from a current controlled five-phase voltage source inverter and the inverter is supplied from a three-phase active front end converter. The novelty of the paper lies in the development of the five-phase drive with the active front converter. The front end converter has two control loops, the dc link voltage control and the source side current control with unity power factor operation. Simple hysteresis controllers are used to control the input from the source and output to the load currents (five-phase induction motor stator current). The validity of the control is validated using analytical, simulation and experimental approaches.","PeriodicalId":135966,"journal":{"name":"2012 IEEE International Conference on Power and Energy (PECon)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131765399","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}

It links power generation, transmission and distribution. There is a huge investment required to acquire or replace them and when they fail, huge losses are incurred in terms of assets, revenue and customer good will. This huge financial burden due to sudden losses of power transformers can be minimized through effective condition monitoring and diagnostics. This paper presents a computer program developed to interpret the condition of power transformers by the analyzing the dissolved gases. The computer program developed using C-Sharp (C#) language under WINDOWS operating system is used to assess four different methods of Dissolved Gas Analysis (DGA) technique to predict the condition of the transformer so as to improve the accuracy of the interpretation.

The Discrete wavelet transform (DWT) is used as feature extraction to extracts useful information from the distorted current signal that is generated from transmission system network under effect of the simulated model of (HIF).

Therefore, in this paper Genetic Algorithm which is a meta-heuristics method was applied. The present study proposed the new method of multi-objective optimization methods.

This is mainly due to the attractive advantages of multilevel inverters such as lower Total Harmonic Distortion (THD) in the output voltage, higher efficiency, less stress on the power switches and low Electromagnetic Interference (EMI). The main problem of using multilevel inverters is the number of power switches that normally contributes to the complexity in controlling the power switches and high cost. In this paper a new structure of a nine-level inverter is proposed to improve the multilevel inverter performance by compensating these disadvantages. This topology employs fewer power switches compared to that of conventional multilevel inverters. In addition a modified Pulse width Modulation (PWM) control method has been designed for this new inverter structure that requires less number of carrier signals. The proposed topology and its control method are described and the results of a simulation study conducted have illustrated the performance of the overall system, thus revealing the advantages of this structure compared to conventional topologies.","PeriodicalId":135966,"journal":{"name":"2012 IEEE International Conference on Power and Energy (PECon)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115710575","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 analysis is concentrated on the high frequency sub-band contents of WPT obtained from the d-q components of the differential currents of the relay. It has been found that the analysis in this approach provides enough information to detect any fault in the synchronous generator. This hybrid technique provides good accuracy and fast fault clearance with only one level of WPT of the d-q axis components of the current. Off-Line testing is carried out for the data collected from an experimental work on a laboratory salient pole synchronous generator for different types of disturbances.

Busbar normally used to transmit and distribute current to distribution board in a building. Higher current capacity will naturally increase heat generation in the busduct system. The heat generation normally creates power losses or eddy current losses at the conductor. In this paper, a two dimensional finite element method by Opera 2D software is used for predicting the temperature distribution at initial steady state current carrying capacity of busbar. The current carrying capacity is limited at temperature different between conductor surface temperature and ambient temperature obtained by IEC standard 60430-2. The heat transfer coefficients on the boundaries are calculated by using the Nusselt number. The mathematical analysis is applied to get the current density. The calculated current input in selected phase angle, heat transfer coefficient, heat flux is used as the input of the simulation model. The results depict that the temperature varies due to change in input phase current.","PeriodicalId":135966,"journal":{"name":"2012 IEEE International Conference on Power and Energy (PECon)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116448595","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}
