Abstract

The invention relates to the technical field of communication, and discloses a communication gateway system and an early warning method of a low-voltage distribution network, and the system collects power line channel noise transmitted by a power supply equipment layer in real time through a gateway, carries out the modeling of the power line channel noise through a support vector machine and a wavelet neural network, carries out performance evaluation on the two noise prediction sequences obtained by modeling by using a root-mean-square error, determines an optimal noise prediction sequence with the most accurate noise prediction, compares the optimal noise prediction sequence with a preset safe noise threshold so as to judge whether the optimal noise prediction sequence is abnormal or not, marks the optimal noise prediction sequence if so, and generates early warning information for early warning, and therefore the real-time performance and accuracy of the early warning method for the power line channel noise are improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a communication gateway system and an early warning method for a low-voltage distribution network. Background technique [0002] There are a large number of energy terminal equipment and energy storage equipment distributed in the power Internet of Things environment. These distributed power sources and grid-connected equipment use a large number of power electronic devices, which makes the grid noise more complicated, which is different from the noise distribution in the traditional distribution network. There is a big difference, especially that the impulse noise is a larger proportion of the noise. Therefore, it is of great significance to study the characteristics of power line channel noise under the switching of distributed power sources and the operation status of energy storage equipment in the Internet of Things for the analysis of signal transmission characterist...
