Description

technical field

[0001] The invention relates to the technical field of DC power distribution, in particular to a device and method for on-line monitoring of DC line loss. Background technique

[0002] As the use of direct current becomes more and more mature, there are higher requirements for the monitoring and management of the line loss of the DC line. For distribution management, power operation and maintenance and troubleshooting cannot be carried out in time, which brings a lot of inconvenience to power management personnel. In the past, due to the limitation of the development of the Internet, there was a delay in the transmission of data. Therefore, it is difficult to realize real-time monitoring and management of line loss. But with the development of mobile Internet 5G technology. The data transmission speed is greatly improved. It provides possibility for real-time line monitoring and data transmission. Contents of the invention
