摘要
IEC61850一致性测试涉及到的内容非常庞杂,一般完成IEC61850规约一致性的检测需要不同的工具软件及各类测试仪设备,且规约一致性检测的整个过程都需要有很强专业知识的人员参与,需要关注每个细节,同时对每个检测过程的报文进行分析判断,整个测试非常复杂和繁琐.本文结合过往IEC61850规约一致性整个测试过程中遇到的问题及检测经验,针对目前智能变电站IEC61850一致性测试操作繁琐、缺乏自动闭环测试的问题,提出使用Python编程语言,通过IEC61850的取代服务来实现一致性检测中最为复杂的报告服务全自动测试技术的实现方式,提出了系统的实现方法,该方法通过程序自动判别测试用例和实时报文信息,测试中无需人工干预,提高了一致性测试的执行效率并加强了测试的可靠度和严谨性.相较于以往需要外部施加信号触发生成报告的检测方式提供了新的思路和参考.
The content involved in the IEC61850 conformance test is very complicated.Generally,different tools and software and various tester equipment are required to complete the conformance test of the IEC61850 protocol,and the entire process of the conformance test of the protocol requires the participation of personnel with strong professional knowledge.It is necessary to pay attention to every detail and analyze and judge the messages of each detection process at the same time.The whole test is very complicated and tedious.This article combines the problems encountered in the entire testing process of IEC61850 protocol conformance and testing experience.Aiming at the cumbersome operation of IEC 61850 conformance testing of smart substations and the lack of automatic closed-loop testing,this paper proposes to use the popular Python programming language and pass the IEC61850 Instead of services to realize the most complex report service in the consistency check,the technical realization method of fully automatic test of the report service is proposed,and a system realization method is proposed.The method automatically distinguishes test cases and real-time message information through the program,without manual intervention during the test.It improves the execution efficiency of the conformance test and strengthens the reliability and rigor of the test.Compared with the previous detection methods that require externally applied signals to trigger report generation,it provides new ideas and references.
