EMTP MODELS를 이용한 2차 아크 모델링 기법에 관한 연구 = A Study on the Technique for the Secondary Arc Modeling Using EMTP MODELS

다국어 초록 (Multilingual Abstract)

The most frequent faults on overhead transmission lines are single-phase to ground arc faults in air. On HV/EHV lines, the single-phase autoreclosure is an effective means to clear the fault while retaining the system stability.
For the improvement of an adaptive SPAR(Single-Phase Auto-Reclosure) and novel protection schemes, it is important to simulate arc faults. But, it is difficult to reproduce the real arc behaviour, i.e. the extinction phenomenon exactly by computer simulations due to extremely random behavior of secondary arc.
For simplicity of simulation processing, a simulation language, called MODELS, is used. It has been added to the EMTP, which permits to interface control system with power system.
This paper proposes a new computer modeling techniques for the primary and the secondary arc separately, which can be implemented with EMTP MODELS routine, and the the performance of the proposed model is simulated on a typical 154 [kV] korean transmission line system.
