Abstract: |
The steady state simulation mathematical model of gas distribution networks was established using the nodal analysis method, and the effective algorithm to solve the model was given. In consideration of the pattern of every node that must be given a known parameter in steady state simulation of gas distribution networks, the problem of steady state simulation was widened, which can make the steady state simulation more widely used. The calculation example shows that the mathematical model has a good stability of calculation and convergence property. The calculation results agree well with the prediction ones. |
