CONTROL SYSTEM IN A GAS PIPELINE NETWORK TO SATISFY DEMAND CONSTRAINTS

摘要

Controlling flow of gas in a gas pipeline network, wherein flow of gas withineach pipelinesegment is associated with a direction (positive or negative). Minimum andmaximumdelivery rates to each gas receipt facility are determined. Lower and upperflow bounds ofgas delivery rate are created by bounding minimum and maximum signed flowrates usingminimum and maximum delivery rates, respectively, for each pipe segment. Apressure droprelationship for each pipeline segment within the lower and upper flow boundsis linearized tocreate a linear pressure drop model for each pipeline segment. A network flowsolution iscalculated, which includes flow rates for each pipeline segment and pressuresfor eachnetwork nodes to satisfy the lower and upper flow bounds on the gas deliveryrate. Thenetwork flow solution is associated with control element setpoints used by acontroller tocontrol one or more control elements.
