摘要
认为采样值同步技术是实现数字化变电站过程总线通信的难点之一。阐述了基于外部源的硬接线同步和基于IEEE 1588的网络同步两种方案,指出方案实现的关键因素,从硬件设计、同步误差、冗余性和互操作性等方面对这两种方案进行了分析和比较。研究结果对数字化变电站中采样值同步设计具有参考意义。
Synchronization of sampled values is one of the technical challenges in implementing the process bus communication in digital substations. Two synchronization schemes, of which one is based on external source and the other based on IEEE 1588, are illuminated and compared in the aspects of hardware design, synchronization error, redundancy, and interoperability. The research result is valuable for design of high accuracy synchronization in digital substations.
