Dynamic-state Model[1] Transmission Line Protective Relay Using PSCAD/EMTDC

PSCAD/EMTDC를 이용한 송전선로 보호 계전기의 동특성 모델[1]

In recent years, with the continuous development of modem power system, the need for high performance protection to meet the customers' requests for more stable and reliable power supply has become increasingly emphasized. So, there is urgent need for a proper testing platform about not only existing digital protection relay but also new digital protection relay on the transmission line. It is also dynamic-state test which can test the performance of digital relay. This paper suggests basic system model for testing transmission line protection using PSCAD/EMTDC, and presents the process of the component modeling in the basic system.
