Problems solved by technology

In addition, there is also a mismatch between the power at the outlet of the substation and the total power of the downstream transformers, and the mismatch between the power at the outlet of the station and the total power of downstream users. Therefore, it is difficult to determine the cause of the abnormal line loss.

Abstract

The invention discloses a transformer area line loss abnormity analysis system which can carry out real-time online monitoring on loads of branch points along a 0.4 kV low-voltage transformer area, carries out statistical analysis on the loads and line loss of the branch lines through a background software system, and finds out the reason of mismatching of electric quantity. Operation and maintenance personnel can also access system information through mobile phone APP software, line loss statistical analysis and calculation are completed in a background system according to the network topology model and actually collected data, and the cause of line loss abnormity is checked.

Description

technical field [0001] The invention relates to an abnormal analysis system for line loss in a station area used for automatic maintenance of a power grid. Background technique [0002] The line loss rate is directly related to the economic benefits of power supply enterprises. Improving the level of line loss management and reducing the line loss rate are important goals in the operation of power supply enterprises. In daily work, through the metering at the outlet of the distribution transformer area and the measurement and statistics of the line loss rate at each end user side, it is often found that the line loss rate of the metering area of ​​the distribution transformer area is too high, reaching 50% in extreme cases. In addition, there is also a mismatch between the power at the outlet of the substation and the total power of the downstream transformers, and the mismatch between the power at the outlet of the station and the total power of downstream users. Therefore,...
