Design of digital relay controller on a single chip

디지털 보호 계전기 전용 제어 칩 설계

Protective relay play a crucial role in the proper operation of a power system, and the reliable transfer of electrical power. This paper deals with the design and implementation of a digital protective relay on a single chip. Implementation on the FPGA(Field Programmable Gate Array) of the chip of digital protective relay. This protective relaying chip monitors the frequency and the voltage and current of the power system. And report the voltage, the current. the frequency, active power and reactive power.
