| 摘 要： | 在线路保护中越来越多的采用电流差动保护作为主保护,电流差动保护需要将大量数据信息从线路一侧传向另一侧,误码的大小对保护性能指标影响很大。差动保护装置时钟设定影响通信数据,为尽量减少误码对差动保护的影响,应根据不同的通道方式,采用不同的最佳时钟设置。文章主要分析了差动保护传输数据及不同通道应采用的时钟设置方式。

| Abstract: | More and more current differential protections have been adopted as the main protection in line protection. In differential protections, large amount of data is transferred from one side to another, and the number of error code will be a big impact on the protection performance. The clock device setting of the differential protection affects the data communication, and in order to reduce the influences, the optimal clock settings for different channels should be used. This article mainly analyzes the data transmission of differential protection communication and the clock setting method. |
