연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

This paper presents a new numerical algorithm for the fault location estimation and arcing fault detection when a single-phase arcing ground fault occurs on a transmission line. The proposed algorithm derived in the spectrum domain is based on the synchronized voltage and current samples measured fr...

제안 방법

  • proposed the two-terminal fault location estimation approaches based on unsynchronized data [3]. In this paper the authors utilized the lump-model to represent the short line and made compensation for long lines. The described schemes suit only off-line post fault analysis.
  • In this paper, a new two-terminal algorithm for fault location estimation and arcing detection is derived in the spectrum domain. The proposed algorithms are based on the only use of voltage and current samples that are synchronously taken from assumed PMUs installed at both ends of a transmission line.
  • 4. The data for testing was obtained from simulating the system using the Electromagnetic Transients Program (EMTP) under various fault type and parameter scenarios.
  • The developed algorithms are based on the synchronized phasors obtained by assumed PMUs installed at both terminals of the transmission lines.
  • lines. The proposed algorithm is based on the spectral analysis of the input phase voltages and line current signals measured by numerical relay. Only fundamental and third harmonic phasors calculated by Discrete Fourier Technique are needed for algorithm development.
  • domain. The proposed algorithms are based on the only use of voltage and current samples that are synchronously taken from assumed PMUs installed at both ends of a transmission line. Also, the arc voltage wave shape is modeled numerically on the basis of a great number of arc voltage records.

이론/모형

  • considered to develop the fault algorithm. From the test results, the proposed algorithm for the fault location estimation and fault discrimination can be applied to the long line model. Through the analysis for the various case studies, when considering the shunt capacitance in a long line model, errors of unknown parameter estimation are reduced.
  • If the fault location algorithm does not compensate for shunt capacitance in the long line model, error may be increased to the longer lines on higher voltage levels. In this paper, the distributed line model is used for the development of fault location and discrimination algorithm for long line applications. The line [] model may be corresponded to the distributed ABCD model.
  • The tests have been done using the Electromagnetic Transient Program (EMTP). The schematic diagram of the 400 [kV] power system on which the tests are based is shown in Fig.
