ABSTRACT
With the development of microcomputer technology, the strong performance of microcomputer control is also applied in relay protection technology, microcomputer relay protection test device can fully meet the performance requirements of microcomputer protection test, enriching and improving the performance of relaying protection system. Microcomputer relay protection test device has gone through four developing stages: 1) as an intelligent controller with single-chip period; 2) with PC as the intelligent controller period; 3) using Windows operating system as platform period; 4) using high performance DSP core controller and embedded industrial control computer period. In this process, the relay protection testing technology is heading to mature[2].
