Several algorithms, some for scheduling battery power e.g. Dynamic Voltage Scheduling, Static Voltage Scheduling, Dynamic Power Management etc and other with emphasis on designing efficient routing protocols have been designed in past. Some algorithms, however, address this very issue at software level by writing memory and CPU friendly programs. This paper proposes Self Organizing Maps (SOM) based unsupervised Artificial Neural Network learning technique to enhance average battery life. Proposed system allows all active nodes to transmit their sensory data to the base station node (BSN) which has a 2×3 SOM running on it. Sensor nodes start sending data to the BSN; it keeps on making categories and puts relevant data in appropriate categories/ classes. SOM is trained after it has received a number of such transmissions from active nodes. Class definitions are then broadcast to all active nodes by BSN and from then onwards they transmit only the class definitions (that are fairly lesser in size) to BSN and hence significant battery power is conserved. We have showed an overall 48.5% battery power saving using the above technique.","PeriodicalId":244218,"journal":{"name":"2009 Third International Conference on Electrical Engineering","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115921123","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 this non-sinusoidal current passes through the impedance of the line/cable, it causes considerable distortion in voltage. This distorted voltage in a parallel connection scheme appears at the LT/HT sides of distribution transformer and causes significant effects on equipment performance which are designed to operate at sinusoidal voltage and current only. In this research paper, the complete distribution network of Rachna College of Engineering & Technology (RCET), Pk has been simulated using Electrical Transient Analyzer Program (ETAP) software. For this purpose an experiment has been performed in which current waveform drawn by a PC along with its spectrum has been recorded using oscilloscope at RCET Research Lab as prototype. This model of a single PC is injected into the harmonic library of ETAP for simulation of RCET distribution network. The impacts of harmonics caused by PC's on distribution transformers have been completely analyzed in this research work. Moreover, the trend of Total Harmonic Distortion (THD) with variation in different types of loads has been analyzed mathematically & graphically.","PeriodicalId":244218,"journal":{"name":"2009 Third International Conference on Electrical Engineering","volume":"2019 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114192532","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 has not only confused the power utilities but also has attracted the attention of its customers and equipment manufacturers. Although extensive research work is being done in this field but one of the main problem encountered by its stake holders is the voltage unbalance in electrical power system. The problem of voltage unbalance has affected the safety, reliability and economic efficiency at all levels in power industry. In this research Computational Intelligence Techniques have been used for efficiently predicting the power factor of unbalanced load of a power distribution system. The Principal Component Analysis Technique was used to find the optimized number of new dimensions of PQ data. Finally Feed Forward Back Propagation (FFBP) algorithm was used to estimate the power factor of a distribution network by analyzing the real power system parameters. This research highlights the importance of maintaining power factor close to unity for power utilities to achieve sustainable availability of quality supply of electrical power for its customers. The outcomes of the proposed techniques were compared and tested with the field results of a power utility in Victoria, Australia.","PeriodicalId":244218,"journal":{"name":"2009 Third International Conference on Electrical Engineering","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130003453","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}
