Research on Framework of the Next Generation Power Communication Transmission Network

Abstract

With the development of smart grid, the power communication service presents features of IP, broadband, and intelligence. The traditional transmission network based on Multi-Service Transport Plat (MSTP) cannot adapt the evolution trend of all-IP and ultra long-haul. The cost of Dense Wavelength Division Multiplexing (DWDM) technology also needs to be reduced. In this paper, a new framework of the next generation power communication transmission network based on Packet Transport Network (PTN) and Optical Transport Network (OTN) is proposed. Furthermore, strategies for interconnection and evolution of the current and future transmission network are discussed. The conclusion is that the PTN and OTN based network can solve the problems of traditional MSTP and DWDM network, so it is a suitable scheme for the next generation power communication transmission network.
