A neural network was trained by data from simulation of a simple power system under load and fault conditions, tested by data with different system conditions, and finally run for faults along the whole power line. The research was concentrated on creating more selective arcing fault detection, especially for radial distribution lines where arc resistance can be a significant part of the zero sequence impedance. A nonlinear arcing resistance model was used to provide data and a new operating characteristic was devised. The prospective ANN distance relay showed very good performance in detecting a single-line-to-ground fault with nonlinear arcing resistance along the whole transmission line.","PeriodicalId":153198,"journal":{"name":"Proceedings of International Conference on Intelligent System Application to Power Systems","volume":"38 13","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114036349","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 techniques evaluated are used for the dynamic security assessment of power systems. The feature extraction methods are used to map the observation vectors from the measurement space into a lower dimension feature space. The patterns in the feature space can then be utilized to train a neural network (NN) classifier. The NN classifier is used to classify a given power system into either a \"secure\" or \"insecure\" class. The feature vectors not only represent a reduction in dimensionality, but also lead to an improvement in class dispersion, and hence to a better classification. Two feature extraction algorithms, the minimum entropy method and the Karhunen-Loe've expansion, have been studied to examine their intraset clustering and interset class dispersion. A NN pattern classifier system is developed to illustrate the feasibility of classifying any given operating condition into either secure, or insecure class. Security assessment data from two utility power systems are used to test the proposed techniques.","PeriodicalId":153198,"journal":{"name":"Proceedings of International Conference on Intelligent System Application to Power Systems","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134466558","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}
