| Abstract:In view of the current situation of the relay protection of the smart substation， a secondary system architecture based on the intelligent components of a substation bay is proposed. Based on the architecture， the solution for the intelligent components is proposed， including technical solutions for the line/bus tie bay and the main transformer bay， and the technical solutions for cross-bay protection based on shared networks. The intelligent components for the substation bay vertically integrate multiple service functions so that the number of optical ports of the device is greatly reduced， and the short cable is used for acquisition and tripping to effectively quicken the protection action.The cross-bay protection based on the shared network makes full use of the shared data and has a simple structure and high reliability. The proposed solution can address the problems of too many optical fibers， low quickness and low reliability in the smart substation. |
