The paper focuses on how a numeric directional relay uses the phase relationship of sequence components such as positive sequence (V<sub>1</sub> vs. I<sub>1</sub>), negative sequence (V<sub>2</sub> vs. I<sub>2</sub>), and zero sequence (V<sub>0</sub> vs. I<sub>0</sub>) to sense fault direction, but other concepts such as using quadrature voltage (e.g., V<sub>ab</sub> vs I<sub>c</sub>) are included","PeriodicalId":300971,"journal":{"name":"2006 IEEE Rural Electric Power Conference","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132565740","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}

Data from 85 substations was used in this study. The purpose of the project was to characterize the system power quality and to determine what influences it. Many variables, both system related and weather related, were analyzed. Although there have been previous studies of power quality, this is the first to take a comprehensive look at environmental influences on power quality. One surprising conclusion is that temperature is a stronger predictor of the number of voltage sags than lightning flash occurrence. The system parameter study showed both agreement and disagreement with earlier studies. The results of analysis of the data is discussed in detail along with their implication to improving power quality on rural systems. Besides studying what influences the number of voltage sags, the correlation between the voltage sag index (SARFI) and interruption frequency index (SAIFI) was also investigated. A very strong correlation of an inverse relationship between the two was seen. This implies that by only concentrating on improving power quality one can increase the number of system interruptions. The discussion explores what further studies are needed to find means to improve one without degrading the other","PeriodicalId":300971,"journal":{"name":"2006 IEEE Rural Electric Power Conference","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124278001","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 expectations for more reliable and continuous electricity are growing all the time. Short and long outages in electricity distribution have shown the vulnerability of modern society. The customers' quality consciousness and the role of energy market authority have grown during the last years. In addition, to allow the rate of return of companies, the authority supervises power quality in the sense of reliability. In the near future, power quality is an actual part of the distribution regulation model. The focus of this paper deals with practical experiences of application of the three-voltage-level 20/1/0.4 kV system and results of studies in which alternative network solutions are evaluated.

Accurate fault location expedites repairs and restoration of lines, ultimately reducing revenue loss caused by outages.

We define terms associated with fault location and describe several impedance-based methods of fault location (simple reactance, Takagi, zero-sequence current with angle correction, and two-ended negative-sequence). We examine several system faults and analyze the performance of the fault locators given possible sources of error (short fault window, non-homogeneous system, incorrect fault type selection, etc.).
