Research and Application of Interference-Free Station Area Identification Technology Based on Zero-Crossing Voltage Characteristics

During the operation and maintenance of the distribution network, load adjustment will lead to changes in the relationship between household meters in the area. If the household meter attribution in the area cannot be corrected in a timely and accurate manner, it will lead to confusion in the household meter and meter attribution files, which is not conducive to the refined management of the distribution network. And energy saving and loss reduction. Although the currently existing station area identification technology can alleviate the above problems to a certain extent, it still has problems such as low identification efficiency, high labor consumption, and poor identification accuracy. In view of the shortcomings of the existing station area identification technology, this paper proposes a non-disturbance station area identification technology based on zero-crossing point voltage characteristics, which combines the advantages of zero-crossing point section voltage characteristic identification and signal-to-noise ratio SNR value identification technology to achieve user-friendly Fast and accurate remote online automatic identification of table area belongings.
