Development of the Conformance Test System for Substation Equipment Communication Protocol Part One Design and Application

According to DL/Z 634.56—2004,the instructive document for conformance test based on IEC 60870-5 protocols series that applies to the communication of protection equipment,an introduction to the implementing details and designing mentality in the hardware and software design scheme of simulating the master station auto-test system is given.The hierarchical design and analysis of the applicable conformance of IEC60870-5-103 is made.The static structure of the software adopts modularized programming and the dynamic data exchange uses multi-thread technology.This system takes conformance test as its core while giving attention to the expansibility of the test tool.The test range covers the configuration parameter test of IEC 60870-5-103 protocol and function test.
