基于IEC 61850第二版非侵入式自动测试系统的研制

Non-intruding development of automatic test system based on IEC 61850 edition2.0

为了解决智能变电站二次回路测试效率低和安全性不足的问题,引入了"非侵入式"的概念。基于IEC 61850第二版标准和自动测试技术,研制了非侵入式自动测试系统。首先分析了二次回路测试原理及目的,其次阐述了"非侵入式"系统的关键技术点。最后结合现场实际运行,提出引入了"非侵入式"概念后的安全实施方案和测试流程。通过"非侵入式"自动测试系统对智能变电站二次回路进行测试,实现了工程现场不改变站内装置配置和物理链路,即完成二次回路的测试工作,显著提高了工程测试工作的效率及智能变电站运行的安全性。

In order to solve the problems of low testing efficiency and safety of the two circuits of the intelligent substation, ＂non-intrusive＂ concept test is introduced. Based on IEC 61850 second edition standard and automatic test technology, non-invasive automatic test system is developed. Firstly, this paper analyzes the secondary circuit testing principle and objective, then describes the key technology of ＂non-intrusive＂ system. Finally, combined with the actual operation, it proposes the introduction of a ＂non-intrusive＂ concept of security scheme and testing process. Through non-intrusive type automatic test system of intelligent substation secondary circuit testing, the realization of the project site does not change the station device configuration and physical link, namely, the completion of the testing work of secondary circuit significantly improves the engineering test work efficiency and intelligent substation operation safety.
