A parameter identification method for natural gas supply systems under unsteady gas flow

We consider the identification problem for the technical parameters, i.e., hydraulic efficiency coefficients, of gas transmission systems (GTS) under standard unsteady gas flow. Coefficient estimation is reduced to a conditional optimization problem with equality type constraints. We propose an algorithm to solve it. The algorithm's efficiency has been tested with computational experiments, including a looped gas supply system. The resulting model operates under the current level of GTS information support.
