To grasp the true situation of line loss

the realization of data quality control in power grid line loss statistical information is discussed by using certain techniques such as electric energy automatic data acquisition

equipment ledger maintaining and estimating

computer monitoring and information management. By establishing a unified data platform of line loss information management system and using the methods such as the illegal data flexible treatment

the data verification

the traceable data correction and so on

we can set up the control mechanism of the grid line loss data and the grid equipment ledger data. It is shown by practice that the control mechanism can significantly improve the matching rate of equipment ledger and the automatic acquisition rate of electric energy data.
