A REAL TIME LOSS COMPUTATION METHOD BY MINIMUM NIGHT FLOW

摘要

In the present invention, when an event in which a minimum flow value changes occurs, the initial flow is initialized to reflect the event, and the minimum flow value is determined as a property. The method of calculating the minimum flow value is based on a trend analysis of flow data occurring in the night time, The present invention relates to a method for calculating a loss amount by analyzing a real time daily minimum flow amount interval reflecting an occurrence of an event that can calculate a usage amount and a loss amount in real time, 1) collecting flow data at each point; 2) correcting the data; 3) extracting data for analysis; 4) determining the lowest flow rate; 5) Estimating the nighttime use of the lowest flow rate day; 6) calculating the nighttime usage of all days; 7) determining whether a new nighttime minimum flow value has occurred; 8) when a new minimum flow rate value has occurred, returning to step 4) and revaluing the lowest flow rate value; 9) analyzing the daily nighttime usage and leakage if the new nighttime minimum flow value does not occur; 10) judging whether or not an event is generated, and if an event occurs, returning to step 4) and re-valuing the minimum flow value; 11) determining whether or not an event has occurred and calculating the daily minimum data if an event does not occur; 12) Estimating the remaining value obtained by subtracting the minimum data value for each day from the minimum data value to the night minimum use amount.;
