Abstract: With the rapid development of power grid, the security, economy and stability of power grid depend more and more on the communication system, and the rapid development of communication technology, especially optical communication technology, is more and more widely used in the production environment. As an important part of the power communication system, the communication equipment SDH, carries the production and management services such as power information, dispatching data, communication data, relay protection, video conference, video surveillance and so on. The normal operation of SDH equipment is an important guarantee for the communication and network connection of each substation and power supply station. Once the SDH equipment fails, the communication network of the whole substation and power supply station may be paralyzed, which will greatly affect the normal development of the work of various departments. This paper mainly studies and summarizes the treatment of several faults of SDH equipment, such as temperature crossing line of CSF cross board, time slot docking, network data inconsistency and so on.
