Abstract: According to the investigation of automation test task in the construction of new energy transformer substation, it is found that the automatic data channel of OPGW fibre-optical high-voltage line is delayed due to various reasons, which seriously affects the project grid-connected power generation. Therefore, the automation test before the project is put into operation must look for a reliable wireless data channel to replace the formal fiber-optic communication channel, in order to complete the relevant electrical automation test tasks. According to the characteristics and advantages of UHF wireless technology, this paper studies deeply the realization method of communication link based on UHF wireless technology, and fully demonstrates the flexibility of UHF wireless technology as an advance debugging channel in transformer substation construction, it has a positive development prospect.
Keywords: UHF wireless technology; smart grid; COFDM; wireless data channel
