Abstract:
Controlling flow of gas in a gas pipeline network, wherein flow within each pipeline segment is associated with a direction (positive or negative). Minimum and maximum signed flow rates are calculated for each pipeline segment constituting lower and upper bounds, respectively, for flow in each pipeline segment. A nonlinear pressure drop relationship is linearized within the lower and upper flow bounds to create a linear pressure drop model for each pipeline segment. A network flow solution is calculated, using the linear pressure drop model, and includes flow rates for each pipeline segment to satisfy demand constraints and pressures for each of a plurality of network nodes to satisfy pressure constraints. Lower and upper bounds on the pressure constraint comprise a minimum delivery pressure and a maximum operating pressure, respectively. The network flow solution is associated with control element setpoints used by a controller to control one or more control elements.

Claim (Index 2):
The system of  claim 1 , wherein calculating a network flow solution to satisfy pressure constraints comprises:\n bounding a maximum error in pressure drop estimation for one or more of the plurality of pipeline segments as a maximum difference in estimated pressure drop between the linearized pressure drop model and the nonlinear pressure drop relationship; bounding a maximum error in pressure estimation for a node as a function of the maximum error in pressure drop estimation for the one or more of the plurality of pipeline segments; and using the linearized pressure drop models to calculate a network flow solution such that a node pressure estimate produced by the linearized pressure drop models is less than the upper bound pressure constraint minus the maximum error in pressure estimation and greater than the lower bound pressure constraint plus the maximum error in pressure estimation.
