Causal Analysis and Control of Line Loss Based on Daily Line Loss Rate Curve Characteristics of Transformer Area
Reasons for abnormal daily line loss rate within a transformer area are diversified and complicated,which re-sults in elevated difficulty of causal search and control of line loss anomalies.This study tentatively adopted the voltage drop method to calculate theoretical value of daily line loss rate,and determined the cause of anomaly by comparative anal-ysis between theoretical and actual values.And it was obtained by analyses that the causal determination for electricity theft,gateway metering deviation or faults,clocking anomaly,and undercharge supply,can refer respectively to excess plus fluctuation,excess plus stability,fluctuation plus small average-to-theoretical value differences,and negative values,of daily line loss rate.The correctness of the aforementioned principles was proved through methods such as theoretical a-nalysis and practical experiment with line loss testers.
