Yang Xue-fang · Journal of Shanghai University of Electric Power · 2011
The causes of errors of the telemetry SCADA system is described and some data error detection methods are described.By applying the T-SQL query language commands in the database,the query expression is applied at 3 to 4 o'clock data points,which can effectively avoid the error caused by capacitor effect and estimate the abnormal information.Morever,the method also has characteristics of high calculation speed and small workload.
