| 摘要: |
| 建立了一次系统和保护通道的动模试验模型，设计了动模试验测试项目，针对各项目提出了具体的测试要求，并按照要求对继电保护的通道切换装置进行测试。测试结果表明，被测的继电保护通道切换装置基本满足技术要求，但是在给断电的切换装置重新上电后，或者备用通道延时增加、调整切换装置缓存后若立即发生区外故障，则保护容易发生误动。对误动的原因进行了分析，并提出了对应的解决方法。 |

| Abstract: |
| The dynamic simulation model of primary system and relay protection channels is built，and its test items are designed. The corresponding test requirements are proposed and the channel switching device of relay protection are tested accordingly. The test result shows that，the tested channel switching device basically meets the technical requirements，but it may operate improperly when out-zone fault occurs immediately after it is repowered or its cache is adjusted together with the increased time delay of the backup channel. The reason of misoperation is analyzed and the solutions are given. |
