Data Fusion of Vacuum Measurement in Vacuum Switchgears
The reliability of power grid is affected by the changes of vacuum level in vacuum switchgears. In this paper, the data fusion of two kinds of vacuum measurement methods is discussed which is used in the expert system for vacuum measurement. First, the consistency test is done for a kind of vacuum measurement by using distribution method. Taking vacuum measurement data in 10 days as a unit, the fusion values are obtained through doing data fusion treatment then the fusion values of vacuum level with two kinds of measurement methods are processed by using adaptive weighted algorithm, so more accurate vacuum measurement values can be obtained, and the theoretical basis can be found for establishing a dynamic database of expert system.
