REAL TIME LOSS COMPUTATION METHOD BY USING MINIMUM NIGHT FLOW

摘要

PURPOSE: A loss calculating method by a real-time daily minimum flux section analysis is provided to presume daily loss more accurately by analyzing a pattern of a minimum flow section through regression analysis. CONSTITUTION: Flow data is collected at constant time interval(S10). 1-hour moving average flow data and daily flow data are obtained(S11). Analysis target data of an analysis section is extracted from the 1-hour moving average flow data(S12). The analysis object data is classified into a reducing unit, a base unit and an increment unit (S13). A trend line is generated by applying the reducing unit and the increment unit(S14). The lowest value of a polynomial trend line is reduced from night time minimum flow of the flow measuring data(S16).
