A method for ensuring power line communication when a power line is in a fault and maintenance state

Abstract

The invention relates to a method for ensuring communication of an electric power circuit in fault and maintenance states. A to-be-detected electric power circuit used for electric power circuit communication and a communication module arranged on the to-be-detected electric power circuit are provided. The communication module comprises a coupler which is coupled to the to-be-detected electric power circuit, a far-distance electric power circuit broadband communication device and a computer terminal. The computer terminal acquires to-be-detected electric power signals of the to-be-detected electric power circuit through the coupler, compares the to-be-detected electric power signals with reference electric power signals in the computer terminal and judges current operation states of the to-be-detected electric power circuit. The computer terminal adjusts electric power carrier sending power of the electric power signals according to the current operation states of the to-be-detected electric power circuit by controlling the far-distance electric power circuit broadband communication device, and injects the signals into the to-be-detected electric power circuit, so electric power circuit communication of the to-be-detected electric power circuit is ensured.

Description

technical field [0001] The invention relates to a method for ensuring power line communication when the power line is in fault and maintenance state. Background technique [0002] At present, China's broadband power line communication technology (BPL) is getting more and more attention. It is undoubtedly a good choice to provide users with network services quickly and at low prices, especially in remote areas. However, the current power line communication technology does not have much in-depth research on the communication guarantee methods when the line is in a fault and maintenance state, and the medium voltage power line is generally in a relatively remote area, and the line is prone to failure due to the influence of various natural environments. The electric power sector also needs to regularly overhaul the lines, so research on ways to ensure power line communication when the line is in overhaul or fault state, and the communication system deduced through a series of e...
