摘　　要：随着智能电网的迅速发展,"广域保护"、"广域同步相量测量"等新兴业务的出现发展对电力全网时间同步提出了新的要求。传统的全球定位系统(global positioning system,GPS)时间同步系统已无法满足业务的需求,成为智能电网发展的瓶颈。为此,分析电力业务对时间同步的需求,给出电力时间同步系统存在的主要问题,并在此基础上提出全网时间同步的建设思路与组网结构,并对系统进一步的发展与研究的关键问题进行分析。With rapid development of smart grid, occurrence and development of newly-developing business such as wide area protection and wide area synchronized phasor measurement raises new requirements for time synchronization system of elec- tric power whole network. Meanwhile, traditional global positioning system time synchronization system can not satisfy de- mands of business which has become bottleneck to development of smart grid. Therefore, this paper analyzes demands of e- lectric power business for time synchronization and points out main problems in electric power time synchronization system. In addition, it proposes construction thinking and networking structure of whole network time synchronization and analyzes key problems of further development and research.
