Yuanyuan Li, Wei Zong, Lianguang Liu · 2013
Intelligent Substation in the power system is an important factor. In order to meet the power system require- ments, the system constantly optimizes power communication network structures, including massive introduction of new communications technologies, making electric power communication network more complex than ever. Factors affecting the substation communication safety are increasing. Substation communication network security problems become more complex. In this paper, intelligent substation communication networks based on intelligent substation communication network development process are briefly described, and the advantages and disadvantages of several communication technologies are analyzed and compared. In the end of the article, this paper comprehensive analyzed substation information system threats, present management situation and management system in actual operation.
