Abstract: Dispatch's requirements for communication system are analyzed. According to dispatch's characters, a communication system using IP over APDH technology is introduced. The backbone of communication system is APDH system. The voice and data of substation automation system access APDH system by PCM, and the data of distribution automation access APDH system by IP. The APDH system has the advantages of moderate capacity, self-healing loop network, one step multiplexer and perfect network management. The DA communication system over IP follows ISO's layered approach, incorporates all ISO layer 1&2 protocols, and uses protocol built-in QoS and real time features.
