One critical aspect of power quality studies is the ability to perform automatic power quality data analysis and categorization. This paper presents an approach that is able to provide the detection and time location as well as the identification of power quality problems. The method is developed by using the discrete wavelet transform (DWT) analysis. The given signal is decomposed through wavelet transform. Later, using the wavelet coefficients, feature extraction is done and an artificial neural network is developed to classify the power quality disturbances. The training and testing data required to develop the ANN model is generated through simulation. In this paper, it is demonstrated that each power quality disturbance has unique deviations from the pure sinusoidal waveform and this is adopted to provide a reliable classification of the type of disturbance.","PeriodicalId":227812,"journal":{"name":"2006 India International Conference on Power Electronics","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123514528","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}

Real and reactive power on a transmission line in an integrated network is governed by the line impedance, voltage magnitudes, the angle of differences at the line ends, and the role the line plays in maintaining network stability under dynamic contingencies. Reactive power compensation or control is essential part in a power system to minimize power transmission loss, to maximize power transmission capability, and to maintain the system voltage within desired level. In this paper a new method is proposed which improves the power factor automatically of varying lagging loads to unity, using one single large shunt capacitor instead of using a bank of switching capacitors. Basically, this control scheme is a static power factor correction method by continuous voltage or current control of a capacitor. In this work the voltage across the capacitor is being changed by a bi-directional switch to control the magnitude of compensating capacitor current and thereby attaining unity power factor. This system incorporates high-speed insulated gate bipolar transistor switching technology. The gate signal of the switching devices is generated by using a compact and commercially available IC chip SG1524B. The scheme is simple in this sense that it uses only one static bi-directional switch controlled by an electronic control circuit that uses only analog ICs and some discrete digital components.","PeriodicalId":227812,"journal":{"name":"2006 India International Conference on Power Electronics","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132243101","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}
