Problems solved by technology

[0003] At present, the traditional theoretical line loss calculation system of distribution network mainly has the following shortcomings: 1) The real-time performance is weak

The traditional line loss calculation system is actually post-event estimation. Although it is gradually normalized, it lacks real-time performance, making it difficult for it to perceive changes in line loss status in real time and guide distribution network operation dispatchers to optimize the operation mode in a timely manner.

2) The accuracy is poor and the degree of refinement is low

The traditional line loss calculation system uses manual data collection, calculation, and summarization, which is difficult to avoid the deviation or even error of the calculation results caused by human errors, and even has the problem of reduced accuracy caused by insufficient data simultaneity.

3) Low work efficiency

Regarding the data quality analysis and processing module, some scholars have pointed out the problem of abnormal data collection and proposed some processing measures for bad data identification and abnormal collection data processing technology, but they have not yet solved the problem of distribution network fragmentation operation and other working conditions. Mentioned, nor pointed out, the method of network connectivity identification and processing for distribution network line loss calculation

At the same time, there are few patents and literature reports on bad data identification and processing technologies such as active power and reactive power circulation data in substations
