摘要（英）：

The invention disclose a three-phase multipath power line power frequency communication method facing an intelligent power distribution network. The three-phase multipath power line power frequency communication method comprises steps of adopting a three-phase simultaneous transmission mode to perform downlink power frequency communication and combining the three-phase simultaneous transmission mode with a quadrature coding mode to perform uplink power frequency communication. The invention also discloses a three-phase multipath power line power frequency communication system applied for the three-phase multipath power line power frequency communication method facing the intelligent power distribution network. The three-phase multipath power line power frequency communication system comprises power frequency communication substation devices and a power frequency communication terminal; when downlink power frequency communication is performed, the power frequency communication substation devices arranged at a substation simultaneously modulate at A,B,C three phases; and when uplink power frequency communication is performed, communication rate is improved through multiple feeder lines, a three-phase uplink simutanous transmission mode and a single-phase quadrature coding multipath transmission mode. The three-phase multipath power line power frequency communication method facing the intelligent power distribution network and the three-phase multipath power line power frequency communication system can greatly improve power frequency communication rate on the premise that the communication performance is guaranteed.
