摘要：
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.
