Power line communication apparatus and power generating system

A power line communication apparatus, wherein the power line communication apparatus comprises a first power line communication device disposed at a signal transmit end, a second power line communication device disposed at a signal receive end, a power line, a first magnetic ring disposed at the signal transmit end, and a second magnetic ring disposed at the signal receive end;

• under actions of the first magnetic ring and the second magnetic ring, the power line transmits, from the signal transmit end to the signal receive end, a modulated signal coupled by the first power line communication device, so that the second power line communication device receives the modulated signal from the power line;
• the power line comprises a first line for transmitting electric energy and a second line not for transmitting electric energy;
• and
• the first magnetic ring and the second magnetic ring are coupled to the second line.

A power generating system, wherein the power generating system comprises a plurality of power devices, the power line communication apparatus is disposed between every two of the power devices, and an intermediate- or high-frequency signal between every two of the power devices is transmitted through a power line routed between the two power devices;

• wherein the power line communication apparatus comprises a first power line communication device disposed at a signal transmit end, a second power line communication device disposed at a signal receive end, a power line, a first magnetic ring disposed at the signal transmit end, and a second magnetic ring disposed at the signal receive end;
• the power line transmits, from the signal transmit end to the signal receive end, a modulated signal coupled by the first power line communication device, through the first magnetic ring and the second magnetic ring, so that the second power line communication device receives the modulated signal from the power line;
• the power line comprises a wire for transmitting electric energy and a shield layer that wraps the wire for electromagnetic shielding, and the wire and the shield layer separately extend from the signal transmit end to the signal receive end;
• and
• the first magnetic ring and the second magnetic ring are separately coupled to the shield layer.
