Abstract

Currently, most areas of the State Grid are still using a large number of multiplexed 2 M optical fiber channels using photoelectric conversion equipment to transmit relay protection signals. After a long period of use and exploration, this technology is already a relatively mature solution, but it also has some shortcomings, such as complex photoelectric conversion links, large-scale communication equipment in the early stage, and lack of direct communication between relay protection devices and optical transmission equipment. By studying the SDH E1 mapping path, this article refers to the ITU-T standard to analyze the feasibility of the direct interconnection between the relay protection device and the 2M optical interface of the optical transmission equipment. By eliminating the photoelectric conversion equipment, the relay protection equipment and the optical transmission equipment are directly interconnected. In response to the "one specialization and three complex" requirements of the State Grid, a business model based on 2M optical interfaces was proposed. After analyzing and comparing the communication delay with the original business model, it is found that the delay of the business model based on the 2M optical interface has been significantly improved.
