Basing on the characteristics of the superimposed currents in Teed feeders, a unique differential criteria was proposed and analyzed under different operating conditions. This criteria inherently has sufficient sensitivity for internal faults and stability for external faults. Particularly, it copes well with both the internal high resistance faults on a heavily loaded feeder and the out-feeder problem. Extensive simulation studies were conducted on a typical EHV teed line model using EMTDC package. Theoretical analysis and simulation results demonstrates that the new differential scheme provides adequate reliability and fast operating response for a variety of system and fault conditions","PeriodicalId":267582,"journal":{"name":"2006 IEEE Power Engineering Society General Meeting","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114167203","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 first one is based on a nonlinear refinement of a high order fitting of a frequency domain function, while the second one is a simple use of the vector fitting subroutine forcing a low order fitting. The high order system is also obtained via vector fitting. Both models are tested in the frequency domain and in the time domain. The time domain results were obtained via a numerical Laplace transform but they could easily be implemented in electromagnetic transients-(EMT) type of program. The results have shown that while the low order obtained with vector fitting tends to average some of the poles, the nonlinear refinement is capable of selecting a \"minimum set\" of the poles of the high order function","PeriodicalId":267582,"journal":{"name":"2006 IEEE Power Engineering Society General Meeting","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121889070","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}

However, the results of a nationwide survey of recorded information used for calculating distribution reliability indices performed in 1998 by the IEEE/PES T&D Committee Distribution Subcommittee Working Group on system design indicated that significant inconsistencies exist in current data collection processes used within the industry.

The main focus of this study was to investigate the possibility of using a fault current limiter (FCL) to address the above issues. A case study was carried out for a 20 kV distribution network in interactive power system analysis (IPSA) simulation package. Connection of a DG to the considered network increases the fault current closer to the rating of two switchgears and disturbs the O/C protection coordination. An FCL is introduced and varies its impedance and location of installation to investigate the limiting capability and effect on protection coordination. The modifications required to O/C protection scheme for proper coordination were also investigated.

This methodology proposes to make the investment appraisal using a probabilistic framework. The probabilistic production simulation (PPC) algorithm is used to compute the expected energy generated, taking into account system load variations and plant forced outage rates, while the Monte Carlo approach has been applied to model the electricity price variability seen in a realistic network. The model is able to capture the price and hence the profitability uncertainties for generator companies. Seasonal variation in the electricity prices and the system demand are independently modeled. The method is validated on IEEE RTS system, augmented with realistic market and plant data, by using it to compare the financial viability of several generator investments applying either conventional or directly connected generator (powerformer) technologies.
