摘要/Abstract

摘要： 分布式发电自动化系统未来的趋势是变电站以及变电站到分布式系统的每个节点之间都采用IEC 61850标准实现无缝通信。IEC 61850对采样值同步精确度有着非常高的精确性要求。分析并介绍了IEEE 1588协议，单独设立时标生成器，对交换机实现边界时钟功能。提出了一种符合IEEE 1588协议，可用于分布式系统保护通信中的精确时间同步新方案，并给出了软硬件结构模型。IEEE 1588协议的实现利用微控制器来完成，可以满足基于IEC 61850的分布式保护通信系统的采样值同步要求。

Abstract: The future trend of the distributed automation system is adopting the IEC 61850 standard to realize seamless communication in the substation and between the substation and every node of the distributed system. The IEC 61850 protocol has very high requirement for sample value synchronization accuracy. The IEEE 1588 protocol was introduced and analyzed. A separate timing index generator was established, and “sideclock”function for exchanger was realized. A new accurate time synchronization scheme was proposed which is in accordance with the IEEE 1588 protocol and can be used in distributed system protection communication, and the software and hardware structure modes were given. The realization of the IEEE 1588 protocol was accomplished by using microcontroller, and the requirement of sample value synchronization of distributed protection communication system based on IEC 61850 protocol should be satisfied.

Key words: IEEE 1588 protocol, distributed system, synchronization of sample values
