(The primary attributes of the power grid are: (1) The f voltage level is low. The line-shoe voltage of the carrier communication is mostly 35kV, which determines that the noise on the line is low (see Table 1), and it is easy to obtain a higher signal-to-noise ratio. @Line is short. This determines that the transmission loss of the carrier signal bus on the line is small. Under the premise of satisfying a certain signal-to-noise ratio, a cheap model with a lower signal transmission rate can be used.
