摘要
针对2起RCS-931型继电保护64K通道的典型故障现象,进行了详细的分析和研究。分析了电流差动保护装置、PCM和光端机通信设备之间的2M、64K通道配合关系,并结合纵联电流差动保护工作原理,在现场通道试验基础上,阐明了通道故障产生的原因,64K保护用通道存在的缺陷,提出了行之有效解决方案和整改措施,为使用64K通道的光纤纵联差动线路保护运行管理提供了借鉴意义。
According to two typical faults of 64K channel of RCS-931 relay protection, this paper makes detailed analysis and research. It analyzes the relationship of 2M channel and 64K channel between the current differential protection device, PCM and optical communication device. Then, based on channel experiments, combined with the principle of current differential protection, the paper clarifies the cause for channel fault and the protection device defect of 64K channel. This paper puts forward some effective solutions and modification measures for the protection operation and management of 64K channel.
