摘要

为了提高智能变电站继电保护装置测试效率和测试脚本的重用性,提出一种基于分布式设计、测试功能可扩展的继电保护自动测试平台解决方案.在分析智能变电站继电保护装置特点和测试平台需求的基础上,提出以数字化测试仪为主要平台的自动测试系统的设计方案,通过分布式设计架构实现测试功能扩展.通过测试脚本中语义及语法规则以及特征字典定义,实现虚拟化测试脚本编辑和生成,测试执行时通过对虚拟化测试脚本信息二次映射,生成具有一定对象、可执行实例化测试脚本,提高测试脚本的重用性.实际应用效果表明,该系统可提高继电保护装置测试效率,允许测试脚本跨装置重用,提高自动测试平台的实际使用价值.%In order to improve the testing efficiency and the reusability of the test script, a relay protection automatic test platform based on distributed design and test function is proposed. On the basis of the analysis of intelligent substation relay protection device characteristics and test platform requirement, this paper proposes a design scheme which takes digital tester for main platform of automatic test system and implements test function expansion through a distributed architecture. Through the semantic and grammatical rules and feature dictionary definition in test scripts, virtual test script editing and generating are realized. When the tests are performed, an instantiation test script with a certain object and performability is generated by virtual test script information secondary mapping to improve the reusability of test script. The practical application results show that the system can improve the testing efficiency of relay protection device, allow the test script to be reused across devices, and increase the practical application value of the automatic test platform.
