Problems solved by technology

[0002] At present, the most commonly used transmission medium for line differential protection devices is fiber optic channel. Fiber channel has advantages and disadvantages. Usually, the line protection equipped for each line needs to lay special optical fiber with the same length as the line, and the construction cost is high. In addition, although fiber channel Not subject to interference from the electromagnetic environment, but the object itself is relatively fragile, and is easily damaged by foreign objects such as natural disasters, resulting in data channel failure

Description

technical field [0001] The present invention relates to the technical field of relay protection for power systems, and more specifically, relates to a wireless communication device suitable for line differential protection. Background technique [0002] At present, the most commonly used transmission medium for line differential protection devices is fiber optic channel. Fiber channel has advantages and disadvantages. Usually, the line protection equipped for each line needs to lay special optical fiber with the same length as the line, and the construction cost is high. In addition, although fiber channel It is not interfered by the electromagnetic environment, but the object itself is relatively fragile, and it is easy to be damaged by foreign objects such as natural disasters and cause data channel failure. [0003] As a mobile communication system for 2020 and beyond, 5G will penetrate into various industrial fields with its high transmission rate and high transmission r...
