Development of Learning Board for the Digital Relay Using DSP

DSP를 이용한 학습용 계전기 보드 개발

A relaying board is developed for the study of digital relay, which is based on Digital Signal Processor(DSP). The present development is capable of understanding and application for digital relay hardware. To support the design of relaying hardware, first A/D convertor MMI and serial port for communication are embedded, and next a booting cables of three types are supplied. More particularly the relaying board that is convinient to test digital relaying algorithm. This paper concludes by implementing the distance relaying algorithm into a relaying board, the hardware test results show practically high performance.
