摘要
根据智能电网对时间同步高精度和高安全性的要求,给出了智能电网时间同步方案,采用北斗卫星导航系统/全球定位系统双模授时和IEEE 1588协议相结合的电力系统时间同步技术。根据运行模式和授时精度的不同,分别给出了适用于主站、子站的不同时间同步配置方案,从而实现整个智能电网的时间同步。
The time synchronization for the smart grid must have high accuracy and high safety.According to this requirement,a time synchronization scheme for smart grid was given.In this scheme,the power system time synchronization technology,in which the Beidou/GPS dual mode timing and the protocol IEEE1588 are combined,was adopted.According to the differences of operation mode and desired timing accuracy,different time synchronization configuration schemes suitable for the master station and suitable for substations were given respectively.Then the time synchronization of whole smart grid was realized.
