Real-time Testing and Hardware Design of Intelligent Electronic Device for Power Transformer Protection

전력용 변압기 보호를 위한 통합보호제어장치의 하드웨어 설계와 실시간 성능 시험

This paper proposes a prototype IED hardware design and it's real-time experimental results. To evaluate performance of the IED, the study is well constructed power system model including power transformer utilizing the EMTP software and the testing is made through simulation of various cases. The relaying that is well constructed using DSP chip and RISC CPU etc. has been developed and the prototype IED has been verified through on-line testing by LabVIEW simulator. The results show that an advanced relaying based prototype IED never mis-operated.
