| Abstract: | In pilot distant protect system,instead of using high-frequency transceiver,long-distance signal transferring device can overcome unreliability caused by power line carrier channel multiplexing.Therefore,transmission speed and capacity of line is increased quite a lot so,that significantly enhanced reliability,accuracy and timeliness of line protection and automatic safety device.Using fiber channel to achieve the distant data transfer is the best transmit technology in smart grid.In addition,the mechanism ... |
