Research on interim communication in power transmission engineering

In order to solve the problems that when to adopt interim communication and which scheme is better in power transmission project, firstly, the applying situation of interim communication is analyzed systematically in this paper, and then the traditional solutions are summarized in order; Secondly, an interim communication scheme based on Optical Transfer Network (OTN) is proposed; Finally, these schemes are compared in detail, the target applications and selection process are deduced, which has very important significance for optimizing the allocation of interim communication resources as well as guiding the interim communication construction.
