Application and Research of New Technology in Intelligent Substation Communication

摘要

Based on the analysis of the characteristics of new communication technologies, the paper mainly analyzes the adaptability of OTN technology, PTN technology and softswitch technology in power system communication network. According to the demand for the construction of the communication system in the intelligent substation, an application scheme for new intelligent substation communication technologies is proposed, then the technical and economic level of each scheme is compared to optimize equipment allocation, improve reliability, reduce maintenance investment, and reduce investment and energy saving.
