摘要
提出了一种基于PTP(IEEE1588)的故障行波定位系统。分析了PTP同步时钟原理;搭建了故障行波定位PTP同步时钟网络;最后,阐述了影响PTP时钟同步网的主要因素。相比于GPS行波定位系统,该同步网络成本低,不受气候、位置、环境等因素影响,能够满足各个行波故障定位系统之间的时间统一需求,简单可靠,具有明显优越性,对维护电网安全运行与社会稳定具有重要意义。
A kind of traveling wave fault location system based on PTP（ IEEE1588） is presented in the paper. The principle of PTP synchronous clock is analyzed. And structure of PTP synchronous clock network based on traveling wave fault location is built. Finally,the main factors affecting the PTP clock synchronization network is illustrated. Compared to traveling wave fault location system using GPS,the proposed method has several advantages that the cost is low and it is unaffected by climate,location or the environment. Also,it can meet the demand of clock synchronization among each traveling wave fault location system. In a word,the proposed method is simple,reliable and of obvious superiority,playing great importance on maintaining the safety of power grid operation and stability of society.
