基于IEC61850-9-2 LE的子站一致性测试系统的设计与实现

Design and implement of conformance test system for sub-station based on IEC61850-9-2 LE

针对用于数字化变电站装置通信的IEC61850-9-2 LE协议,介绍了数字化子站一致性测试系统软、硬件设计方案中的实现细节和设计思想。依据《IEC61850-10,Ed.1:变电站通信网络和系统.第10部分:一致性测试》对IEC61850-9-2 LE协议应用一致性进行了分层设计和分层解析。软件的静态结构采用模块化编程,动态数据信息交互采用多线程。本系统以一致性测试为核心兼顾通信测试工具扩展性,测试范围涵盖IEC61850-9-2 LE协议配置参数测试和功能测试。

According to the IEC61850-9-2 LE protocol of digital substation devices communication,this paper introduces the design thought and implement details of software and hardware in conformance test system.Based on ＂IEC 61850-10,Ed.1： communication networks and systems in substations Part 10,conformance test＂,it hierarchically designs and analyzes conformance of applying IEC61850-9-2 LE protocol.The static structure of system software adopts modularization programming and dynamic data exchange adopts multi-thread.This proposed system takes conformance test as its core and considers the extensibility of communication test tool at the same time.Its test range covers the configuration parameters test and function test of IEC61850-9-2 LE protocol.
