摘要
根据同步的协议不同,分别比较多MU同步方式PPS、NTP和IEEE1588等的精度和工程实现难易程度.最后提出各种同步方式各有利弊.在实际工程中,需要综合考虑对同步性能的要求、工程开支,以及变电站系统构架等选择合适的同步方式.
The methods for single-MU are hard synchronization and send/no answer, and the methods for multi-MU are PPS, NTP and IEEE1588. The accuracy and the difficult degree of realization are different from each other. In a word, in the synchronization, the requirements on synchronization, expenditures of the project and the systematic structure of a substation should be taken into account.
