Annotation:

The article considers the problem of identifying unmeasurable parameters (coefficients of hydraulic efficiency of pipelines) of large gas transportation systems, which arises when modeling and controlling the modes of operation of gas transportation systems at gas transportation enterprises using computer models and computer software systems. The formulation of the problem and the algorithm for its solution are presented. The problem of insufficient measurements and multiple solutions is described, and appropriate approaches are proposed (introduction of additional terms into the criterion and the implementation of combining pipelines into groups). Using the developed algorithm, the unmeasured parameters (coefficients of hydraulic efficiency of pipelines) of gas transportation systems of varying complexity were identified. The developed algorithm can be used in an automatic mode, close to real time, with the receipt of initial data from the SCADA system.
