继电保护仿真与评估系统的研究

he protection equipments are divided into four structures according to the principles of versatility and convenience based on analyzing the normal protection equipments in-depth. Some general units are broken up and constructed according to the actual mechanics of the protections on this foundation, a suit general relay protection emulation and checking system is exploited. This paper introduces design scheme of emulation platform and function of its realization in detail. This system imitate the actual equipment and improve software modularized by using the object-oriented program technique. At the mean time, it is used in motion analysis of electric system delaying protection and training operational personnel and delaying protection teaching of university. Another ,it is also applied pre-demonstration of delaying protection device and other delaying protection emulation occasion.
