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.

Abstract ▼ AI-Helper 아이콘AI-Helper

Recently, DC systems are considered as efficient electric power systems for renewable energy based clean power generators. This discloses several critical issues that are required to be considered before the installation of the DC systems. First of all, voltage/current switching stress, which is agg...

문제 정의

  • However, it is not an effective approach to install the SFCLs next to all the breakers considering the installation and management costs. This study focuses on minimizing the numbers of the insulated-gate bipolar transistors (IGBTs) by reducing the voltage across the mechanical breakers. The performances of the IGBTs have been verified by many converter applications.
  • This study investigates the SFCL effects on the DC circuit breakers in the practical power system. The voltage surges across the DC circuit breakers are effectively reduced by a set of SFCLs near the substation.

가설 설정

  • It is described in Fig. 8(a) that the fault current through the circuit breaker on bus 36 increases up to 1 kA without the SFCLs. In contrast, the maximum fault current is about 0.
  • During normal operation, a current of 11 A flows from the bus 38 to the bus 39. That is, the sum of the loads on buses 39-44 is larger than the DG generation. In the fault condition, the current direction is changed and the fault current through the circuit breaker on bus 39 comes only from the DG on bus 40.
