Abstract

The invention discloses a distribution network data abnormality monitoring and diagnosis method, which is characterized in that the abnormal data in the operation of the distribution network is classified, and the data abnormality is analyzed to obtain the abnormality cause, locate the abnormal data, and then diagnose the abnormal data, Including the power mutation diagnosis of the gateway metering point and the diagnosis of the file relationship, and then perform data error correction to establish an automatic correction algorithm for data error correction based on arbitrary area segmentation calculations and a statistical iterative data correction method, and comprehensively evaluate the operation of the distribution network through the results obtained through the above operations Health level, through data governance, data anomaly detection and cause analysis, output reports to provide governance basis for the source system, and further realize the safe and stable operation of the distribution network.

Description

technical field [0001] The invention belongs to the field of grid electric power, and relates to a method for monitoring and diagnosing data abnormality of a distribution network. Background technique [0002] In recent years, the country has vigorously developed smart grids, and the intelligent informatization of power transmission and transformation systems has reached a very high level. But in terms of distribution network, due to the complexity of its use environment and structure, the level of intelligence and informatization is low. With the rapid economic growth in my country, the rapid expansion and development of cities, the lack of funds for distribution network planning, construction and renovation, the relatively weak structure of distribution network grids, the insufficient capacity of distribution transformers, and the low reliability of power supply have become increasingly prominent. Distribution network automation The level needs to be further improved. [...
