摘要
同步网作为通信网的三大支撑网络之一,在电力系统通信中起着重要的作用。文章从对频率和时间的同步需求两个侧面,论述了建立宁夏电力数字同步网的重要意义,并从基准时钟源、同步方式、传输链路等方面,探讨宁夏电力数字同步网的建设策略。对建设过程中可能遇到的定时环路问题、低级时钟同步高级时钟等问题,提出了具体的应对措施。
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.
