| Line loss management of power supply enterprises plays a very important role in modern enterprise management.As a key platform for current line loss management and monitoring,measurement automation system can provide data support for enterprise’s line loss analysis and provide a basis for effectively reducing line loss.Data and daily monitoring management support.However,because the line loss management application in the current system still stays at the level of data monitoring,there is no automatic troubleshooting and analysis of line loss anomalies through the system,and relying on manual line loss anomaly analysis will cost a lot of manpower and Time costs.This paper proposes a set of lOkV sub-line line loss anomaly automatic detection application model based on the measurement automation system.Through the refinement and summary of the line loss abnormality investigation method,it sorts out a complete process and method for automatic line loss anomaly automatic investigation.For the design of the next system function requirements,detailed and detailed system operation flow and judgment model are provided.This paper first studies the principle of calculating line loss,and based on the theoretical line loss calculation,provides a reliable reference for the system to judge line loss anomalies.At the same time,the principle of line loss calculation of metrology automation system is further analyzed,which lays a theoretical foundation for the application of line loss analysis.Then this paper analyzes in detail the main abnormal factors of 10kV line fault of power grid enterprises.Basic file accuracy,terminal online rate,measurement failure,meter reading reasons,and electricity theft are the main factors in the current system statistics line loss anomaly.To carry out the research on the 10kV line fault anomaly investigation function of the measurement automation system,the article also combs the line loss data,and finds the key data such as the electric quantity,voltage,current and line change relationship that can be identified and calculated by the system.Based on the analysis of the system analysis process of five main types of line loss abnormalities,such as the terminal is not online,the terminal fails to collect data,and the terminal file error,a lOkV line-line line loss anomaly automatic detection model based on the measurement automation system is established.Finally,based on the work experience,this paper selects three representative practical cases based on the lOkV split line line fault anomaly automatic detection model.One is the typical case where the terminal is not online and the data loss leads to the line loss abnormality.The second is the terminal file.The typical case of the line loss abnormality caused by the error is the typical case of the line loss abnormality caused by the change of the system operation mode to illustrate the scientificity and operability of the model.Relying on the automatic line fault detection and analysis function of the system will greatly reduce the workload of the staff for line loss anomaly and improve the accuracy of the system line loss monitoring,which is of great significance for improving the lean line management level of the power line. |
