| 摘 要： | 2008年的冰灾对线路保护通道产生了严重影响，冰灾中线路保护均采用专用光纤通道对突发情况应变能力太差。通过对常规的几种继电保护通道方式的分析比较，对220 kV线路保护通道配置原则进行了调整。以220 kV方圆－岗阳线为例，根据新的配置原则对线路保护进行了通道配置，通过理论计算分析论证配置的合理性。对新的保护通道配置原则提出了一些看法。

| Abstract: | The snow storm disaster in southern China occurred in early 2008 left a serious impact to the line relay protection channel adhering to the transmission line,due to the poor adaptability to sudden accidents of communication channel based on optical fiber, which is widely used in field of transmission line relay protection.Based on the comparison and analysis of several kinds of commonly used protection communication channels,the principle for 220 kV transmission line protection channel scheme is adjusted . ... |
