Automatic power measurement methods for energy loss in net nested triggers based on database

The present invention relates to automatic power losses theoretical measurement methods based on the database of nested triggers belonging Loss Analysis and Grid Network Technical Field The energy saving system, the method first storage unit period are established network loss energy value and different time Loss metering data amount value, and triggers are defined on the data table; Second, theoretical losses calculation software online real-time value of the unit period of the write data table losses, and losses through the unit period triggers automatic electric quantity data table updated daily measurement value table, the table is automatically updated monthly meter value date measured values ​​by trigger table, the table is automatically updated in the measured value by the trigger month measured values ​​of the table. The invention improves the automation of online net loss analysis; and real-time understanding of the current day, month, changes in the measured value of the loss of electricity in the network; which can detect high-net-loss lines, transformers, etc., to develop scientific Loss Reduction the methods to improve energy efficiency.
