针对部分继电保护装置检测过程存在需要大量人力、测试时间长、准确性差等问题,研究了一套智能变电站继电保护设备自动测试系统。在测试系统中引入云存储和物联网标签技术,智能获取待测保护装置的相关参数,自动生成测试列表。同时将MMS协议集成在测试系统中,可实现测试过程中的实时自动读写保护装置定值、设置测试参数、投退装置软压板来配合当前的测试项目,并自动完成整个测试过程。该系统在整体提升二次系统安全性的同时,可以避免人力、物力的浪费,有效提升实验室检测效率以及现场调试效率,减少基建、检修阶段的时间和开支,对智能变电站的推广应用具有十分重要的意义。

The automatic test system of relay protection equipment of intelligent substation is studied in order to detect the existing relay protection devices.In the test system,cloud storage and isolable technology are introduced,and the intelligent acquisition of relevant parameters of the protection device is obtained,and the test list is automatically generated.At the same time,it integrates the MMS protocol in the test system,which can realize real-time automatic test in the process of reading and writing protection setting value,setting up the test parameters,casting back device soft plate to match the current test project,and automatically complete the whole test process.The system fully improves the safety of secondary system,avoids the waste of manpower and material resources,effectively improves laboratory testing efficiency and on-site debugging efficiency,and reduces the time and expenditure of infrastructure and maintenance.So it is very important for the promotion and application of smart substation.
