Distribution transformer monitoring data cleaning method

The invention discloses a distribution transformer monitoring data cleaning method. The method comprises the steps of collecting and storing measurement data of a TTU; judging whether the null data set, the open-phase data set and the out-of-limit data set of the measurement data in one natural mont...

Zusammenfassung:The invention discloses a distribution transformer monitoring data cleaning method. The method comprises the steps of collecting and storing measurement data of a TTU; judging whether the null data set, the open-phase data set and the out-of-limit data set of the measurement data in one natural month are less than 50% of the total number of the data sets in the month or not; if so, indicating that the month data is invalid; if not, indicating that the month data is valid; judging whether the number of the data sets with the three-phase voltage unbalance degree greater than 15% in the valid data of one natural month is less than 10 or not, and if so, indicating that the data of the month is invalid; if not, indicating that the month data is valid; removing the data sets with the three-phase voltage unbalance degree greater than 15%, judging whether the three-phase voltage daily average value of each day does not exceed the range or not, and if so, judging that the data of the month is valid; otherwise, judging
