초록
In this paper, being different from traditional methods, we design digital protective relay which can be applied to power management and control systems of not only small and medium but also a large scale plants. The digital protective relay was designed with DSP CPU(TMS320C31) to protect and measure more quickly and precisely. We will present test result which it performed according to the standards of Korea Electrical Manufactures Cooperative to prove the faculties of digital protective relay. The test result on the basis of KEMC1120 and IEC60255, show that the operation time error of the digital motor protection relay is improved within
