中文摘要：

变电站在线监测智能电子设备(IED)通过IEC 61850标准通信方式采集并上传一次设备的状态信息到综合应用服务器等站控层装置,是变电站一体化监控系统的重要组成部分,对其进行功能测试是保证系统正常运行的基础。文中通过分析在线监测IED的功能,设计其功能测试用例,通过自动化测试脚本以及测试引擎,代替手动测试,提高测试效率。通过研制的在线监测IED自动化测试系统,以油中溶解气体监测数据上传功能为例,进行了自动化测试实验,并给出了测试流程及测试结果,验证了该方法的正确性和可行性。

英文摘要：

The substation intelligent electronic device (IED) of substation on-line monitoring gathers and uploads status information on primary equipment to comprehensive application server and other devices in the station layer using the communication method in compliance with IEC 61850 standard.As the key device of the integrated supervision and control system,the test of its functions is the foundation of the normal operation of the on-line monitoring system.By analyzing the functions of the on-line monitoring IED,the description of functional test cases is given and the automated testing script and testing engine is designed to replace the manual test,which improves the testing efficiency.Finally,by taking the uploading function of oil dissolved gas monitoring data as an example,an automated testing system for on-line monitoring IED is developed and used to conduct an automated testing experiment.The procedures and results of automated testing are also given to verify the correctness and feasibility of this method.
