智能变电站二次系统基于SCD展开,增加了合并单元、智能终端、交换机等.在应用模式中体现了过程层就地化布置的特征,这样对于保护系统的现场测试带来了很大的不便利性.为了提高现场运行检修的效率,对于基于IEC 61850标准TEST模式的测试方案进行了研究,提出了基于网络发送测试用例的"非侵入式"测试的技术思路和方案,可实现现场不插拔联接光缆,不变更保护整定值,完成现场运维测试.这种测试模式可以带来现场测试的便利性,呈现智能变电站运维测试相对于常规综自系统的独特优势.

The secondary circuit of smart substation is based on SCD, which includes a merging unit, an intelligent terminal, as well as a switch, etc. There is a tendency to implementing process level device at the switchyard, and it means inconvenient to test relay system for maintenance issue. In order to improve the efficiency of site routine test, IEC 61850 based test mode is developed, a new method of "non-intruding test" to test relay system is proposed based on network test case, with which it is not necessary to disconnect fiber and adjust setting on site. Under this circumstances, the test procedure will be improved rapidly and furthermore it can prove the unique benefit of smart substation compared to conventional substation.
