  • 한전에서는 1996년 제주-해남간 HVDC 설치에 이어, 1999년 서대구 S/S에 SVC를 설치하였다. 이와 관련하여 본 논문에서는 한전계통에 최초로 설치한 서대구 S/S의 SVC설비운용과 관련하여 SVC의 이론 및 제어기법과 관련된 일반이론을 소개하고, 설치된 SVC의 기기구성방식 및 특성, 제어특성, 기기사양 등에 대해 간략하게 소개하고자 한다. 서대구 SVC는 345kV/13.5kV, 100MVA급으로서 TCR 및 TSC방식의 하이브리드 방식으로 되어 있다.

  • For a mobile application such as cellular phone, micro fuel cells should be extremely compact and thin. RHFC can be an alternative solution because RHFC gives higher power density than DMFC and does not need ahydrogen storage vessel In this paper, RHFC using methanol fuel is made as a novel planar design without a PROX. Both reformer and cell are made closely in a same plate to share the heater of reformer with the cell. The PBI membrane is used in the cell. The reason is that high temperature of reformer can cause a performance drop when perfluorosulfonic acid membrane such as Nafion is used such a high temperature operation also guarantees the higher CO tolerance to MEA catalyst. The cell is designed as an air-breathing type which the cathode of the cell is opened to the air. The commercial Cu/ZnO/Al2O3 steam reformer catalyst is packed in reformer channel. The active area of MEA is $11.9cm^2$ and the peak power density was $27.5mW/cm^2$.
