“…Supervisory Control And Data Acquisition (SCADA) system is a standard configuration in modern pipeline systems that works as the control center of natural gas pipelines, but rather focuses on the supervisory level [1]. Unlike the advances of the hardware configuration in pipelines, the scheduling scheme is still an empirical decision process [2]. Current industrial practice for natural gas pipeline control involves regulatory control loops along with manual intervention by pipeline dispatchers.…”

With the boost of natural gas consumption, an automatic gas pipeline scheduling method is required to replace the dispatchers in decision making. Since the state space model is the fundamental work of modern control theory, it is possible that the classical controller synthesis method can be used for the complicated gas pipeline controller design. In this paper, a cascade control algorithm is proposed based on the state space model that is used for the transient flow simulation of the natural gas pipelines. A linear quadratic regulator is designed following the classical optimal control theory. Finally, the transient process with different control methods shows the effectiveness of the cascade control using information of the entire pipeline. According to the hardware configuration of natural gas pipelines, automatic scheduling process is ready to deploy as one step to the intelligent natural gas pipelines.

“…However, few of the existing research studies have focused on the gas pressure problem and taken the high-rise buildings into account in the scheduling of the UMIES. Generally, in a horizontal gas pipeline, the change of natural gas pressure is mainly dependent on the diameter and length of the gas pipeline, the volume flow of the natural gas, and decreases with distance due to pipe loss [13,14]. However, in the case of a network with significant differences in height between the start and end points of the gas pipelines, as in high-rise buildings, additional overpressure may occur when the natural gas is transported from lower floors to higher floors.…”

“…Another simulation tool, GassOpt, developed by the SINTEF group, was used to simulate the gas flow considering aspects such as gas quality and gas mixing [20]. A simulation approach was also adopted by Szoplik, who used the GasNet software to simulate the pressures and gas flows in an existing pipeline network and to study their relationship [21]. Even process control models, for example Nonlinear Model Predictive Control, described by Gopalakrishnan and Biegler [22], have been applied to minimize the operational costs in the compressors.…”
