[Abstract]:The energy Internet takes the power system control network as the core, merges a large number of distributed renewable energy, and uses information communication technology to realize the two-way flow of energy and information. Power line communication mainly includes power line carrier and power line power frequency communication technology, they do not need to set up special lines, there is no public communication service cost, they can make effective use of the power grid companies' own resources, under the energy Internet architecture, It has a broad application space in the fields of distributed energy access, optimal operation of microgrid, active load monitoring and so on. Under this background, this paper studies the overall architecture of energy Internet, and analyzes the requirements of distributed power supply for information transmission in normal operation and isolated island operation mode. On this basis, according to the characteristics of power line carrier and power frequency communication, the possible application scenarios of these two power line communication technologies in energy Internet are analyzed. Aiming at the problem of distributed power island detection, a distributed power supply isolated island detection scheme based on power line power frequency communication is designed, and its feasibility is verified by simulation. The downlink power frequency communication signal generator is installed at the bus of the main network, and the power frequency communication signal is detected by the receiving circuit located in the distributed power supply measurement. The isolated island detection is realized by judging whether the downlink modulation signal exists or not. Because the platform of downlink power frequency communication receiving circuit is almost consistent with that of electric energy metering, the reliability of distributed power supply islanding detection can be greatly improved without increasing the cost. In the aspect of power line carrier communication technology, according to the environmental characteristics of energy Internet, the noise characteristics of carrier channel are studied, and the broadband power line carrier channel model is constructed based on parameter matching and transmission line theory. The attenuation of different carrier frequencies in complex line environment is studied. On this basis, a scheme to improve the performance of power line carrier communication is designed. According to the application demand of energy Internet, the monitoring scheme of photovoltaic power station based on power line carrier communication and the monitoring scheme of distributed wind and water power supply based on the combination of power line carrier and power frequency communication are designed.
