摘要

A natural gas passage modeling method for operation control of an integrated energy system, comprising: establishing an equation of partial differential between the flow rate and pressure in the natural gas pipeline on the basis of equations of mass conservation and momentum conservation in a natural gas pipeline as well as natural gas state and flow rate equations; mapping a gas passage to the frequency domain by means of Fourier transform and obtaining a lumped parameter model by means of the two-port equivalent; establishing a natural gas passage general branch model by combining a natural gas booster equation; defining a node-branch incidence matrix and a node-outflow branch incidence matrix, and establishing a natural gas passage topological constraint equation; and establishing a natural gas passage equation by combining the natural gas passage general branch model with the natural gas passage topological constraint equation.
