| Abstract: | The paper introduces that the connection was changed from original duplicate-bus with bypass bus mode into duplicate-bus duplicate-segmentation mode in some switch station. It presents the bus protection of the duplicate-bus duplicate-segmentation connection based on decomposition and combination method and describes the implementation of differential relaying protections. The effectiveness of the protection is proved by the 2 year operation. |
