Meter-transformer connection relationship detection algorithm based on smart meter data

In this paper, we designed an algorithm to detect the meter-transformer relationship. First, the voltage distortion data will be used for preliminary judgment. The voltage distortion data of the central coordinator is compared with the voltage distortion data of each smart meter, and the similarity value between the data will be calculated. Second, we will use the voltage amplitude data to calculate the correlation coefficient between the meter that may be recorded incorrectly. The meter-transformer relationship of the current record is detected by combining the similarity and the correlation coefficient. This algorithm can effectively correct the meter-transformer connection relationship which is incorrectly stored. Simulation and experiment results show that the algorithm has strong versatility.
