光纤继电保护光电转换装置的双电源供电方式

Dual Power Electricity Supply of Photoelectric Conversion Device in Optical Fiber Relay Protection

介绍了山西电网采用继电保护专用通道切换装置方式后,继电保护通道运行率得以提高,主要原因是在各个环节进行了双重化配置。针对继电保护光电转换装置单电源供电的缺陷以及双电源供电方式的必要性、优越性结合实验进行了阐述,望能为继电保护光电转换装置采用双电源供电提高通道可靠性提供理论及实践依据。

In the use of switching device manner of relay protection private channel in Shanxi electric network, the operation coefficient of relay protection is enhanced greatly. The main reason is that every section adopts dual configuration. In the light of the single power defect of photoelectric conversion device in relay protection and the necessity and advantage of the dual power combining with experiment, the theory and practice principle for using the dual power to enhance the channel reliability probability in photoelectric conversion device of the relay protection are proposed.
