Abstract

The invention discloses a broadband communication system of a 10 kV distribution network. The broadband communication system comprises a first inductive coupling unit, a second inductive coupling unit, a first CAN (controller area network) bus unit and a second CAN bus unit, wherein the first CAN bus unit is connected with the first inductive coupling unit; the second CAN bus unit is connected with the second inductive coupling unit; and the first inductive coupling unit is connected with the second inductive coupling unit through a 10 kV medium-voltage power line. Compared with a traditional narrow-band carrier communication technology, the communication speed of an application layer can reach 1M, so that the application capacity is greatly improved, and the foundation is provided for an intelligent distributed FA (feeder automation) mode; and further, peer-to-peer communication is realized during the broadband carrier communication, and the reliability and the communication efficiency are improved remarkably.

Description

technical field [0001] The invention relates to the technical field of carrier communication, in particular to a 10kV distribution network broadband communication system. Background technique [0002] Power Line Communication (PLC, Power Line Communication) uses high-voltage power lines (usually refer to voltage levels of 35kV and above), medium-voltage power lines (refer to voltage levels of 10kV) or low-voltage distribution lines (380 / 220V subscriber lines) as information transmission media. A special communication method for data transmission. The US Federal Communications Commission (FCC) divides power line carrier communication into narrowband power line communication (Narrow over Power Line, less than 1%) and broadband power line communication (Broadband over Power Line, more than 1%) according to the ratio of signal bandwidth to center frequency. . my country's power line carrier communication system has been successfully applied in transmission lines with voltage l...
