Wireless communication device suitable for line differential protection

Abstract

The invention relates to the technical field of power system relay protection, and particularly discloses a wireless communication device suitable for line differential protection, which comprises a first line protection device, a first wireless communication component, a second line protection device and a second wireless communication component, and is characterized in that the first wireless communication component is connected with the second wireless communication component; the first line protection device and the second line protection device each comprise a protection CPU, the first wireless communication assembly and the second wireless communication assembly each comprise a baseband module, a modem, a radio frequency transmitting / receiving module and an antenna module, and the baseband modules are connected with the protection CPUs. The baseband module, the modem, the radio frequency transmitting / receiving module and the antenna module are connected in sequence; and communication performance and data time delay can be monitored in real time, so that safe and stable operation of the protection device is ensured, and the reliability of the protection device is improved.

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...
