摘　　要：结合山西省电力公司 2 .5GSDH光纤环网和太原电力通信SDH光纤环网光纤通道传输5 0 0kV、2 2 0kV线路保护信号的具体应用 ,说明SDH光纤通信系统完全可以满足线路保护信号的传输质量和传输时延的要求 ,可以为继电保护信号提供可靠性较高的传输通道。Based on the protections of the signals in the 500kV、220kV transmission lines in the 2.5G SDH circle fiberoptics net in Shanxi Power Co.and the SDH fiberoptics communications in Taiyuan Power Supply Co.,the paper put forward the opinions that the SDH fiberoptic net can meet the requirements of the quality and timing delay in the protective signals transmission.In addition,the SDH fiberoptic net can provide a high relibale transmission passage for the signals of the relay protection.
