| Abstract: | The synchronous network is one of the three supporting networks in communication network. It plays an important role in electric power communication system. Based on the requirements for synchronous frequency and time, this paper analyzes the impor- tance of constructing a digital synchronous network in Ningxia power grid, discusses the construction strategies by considering the as- pects of clock source, synchronous method and transmission link, and puts forward some practical measures to solve the problems in construction process. |
