Description

technical field [0001] The invention relates to a power and communication signal transmission network architecture, in particular to a new smart grid capable of simultaneously transmitting communication signals and electric energy. Background technique [0002] Smart grid refers to the intelligence of the power grid. It highly integrates and integrates many advanced technologies such as communication technology, computer technology, sensor measurement technology, and control technology with the original power grid facilities to form a new type of power grid, which represents the development trend of the future power grid. . [0003] Traditional communication networks and power transmission networks are often separated. For example, high-voltage lines are used as power transmission networks, while optical fibers are used for long-distance signal transmission, and twisted-pair wires are used for short distances. However, these two methods need to be built through different ne...

Problems solved by technology

However, these two methods need to be built through different network architectures, so they do not meet the needs of smart composite grids. Integrating signal transmission and power transmission is the future development direction

[0004] There are also composite cables that integrate glass optical fibers and cables in the prior art. For example, two Chinese utility model patents with application numbers 201020135132.2 and 200920271986.0 each disclose a multi-core optical cable that integrates glass optical fibers and traditional power transmission cables to achieve simultaneous transmission. The purpose of power and communication signals, but there are still the following defects: First, the core diameter of the glass optical fiber is usually only a few to tens of microns, which encounters great difficulties in laying and installing the terminal of the smart grid-home smart grid, The construction cost is greatly increased; the second is that the glass optical fiber is fragile, which causes great difficulties in later maintenance. The above-mentioned combination of glass optical fiber and traditional cable is intelligently applied in long-distance transmission, and for the last part from the backbone network to the terminal, the application cost is relatively high.
