    • It is responsible for the transmission of all collection and control business data, which is the basic support for the safe, stable and reliable operation of the power system. With the deepening of the construction of power communication network, especially the concept and practice of ubiquitous power Internet of things, higher requirements are put forward for the stability, availability, flexibility and intelligent level of power communication system. The existing power communication network has encountered functional or performance bottlenecks. In order to solve the above problems and effectively support the construction of ubiquitous power Internet of things, it is necessary to introduce SDN technology into power communication network. Based on the investigation of the current situation, this paper studies the SDN interface technology and multi domain SDN technology, and gives the application suggestions of power communication network. Based on the characteristics of SDN technology, such as open, ubiquitous, intelligent, interactive and credible, through unified centralized management,the utilization rate of communication network resources can be improved, the efficient operation of power system equipmentcan be guaranteed, and the intelligent development of power system can be promoted.
