Computational Fluid Dynamics Methods for Gas Pipeline System Control
At the present level of development of long, branched gas transmission networks (GTN), solving the problems of improving safety, efficiency and environmental soundness of operation of industrial pipeline systems calls for the application of methods of numerical simulation. The development of automated devices for technical inspection and process control, and availability of high-performance com...
متن کاملOptimizing Pipeline Control in Transient Gas Flow
Consider a pipeline with time dependent delivery volumes at various load points. Such a system can be controlled by changing with time the pressure setpoints at stations to manipulate flow and linepack. We present an algorithm that computes an optimum set of time-varying setpoint values (out to a user-specified simulation horizon) simultaneously for all stations. These setpoint values are compu...
متن کاملA Supervisory Control Synthesis Case Study : TheAntenna Control System
We devised an algorithm for deriving controllers for timed discrete-event systems with nonterminating behavior modeled by timed transition graphs and control requirements expressed by Metric Temporal Logic (MTL) formulas. This algorithm has several interesting features. Firstly, it simultaneously handles the issues of con-trollability, safety, liveness, and real time in a single framework. Seco...
متن کاملExperimental values for adjusting an automatic control valve in gas pipeline transportation
When a natural gas pipeline ruptures, the adjacent automatic line control valves (ALCVs) should close quickly to prevent leakage or explosion. The differential pressure set point (DPS) at each valve location is the main criteria for value setting in ALCV action. If the DPS is not properly adjusted, the ALCV may mistakenly close or it may not take any action at proper time. This study focused on...
متن کاملSupervisory predictive control of power system load frequency control
Objective: The objective of this paper is to develop a hierarchical two-level power system load frequency control. Design: At the button level, standard PI controllers are utilized to control area’s frequency and tie-line power interchanges. At the higher layer, model predictive control (MPC) is employed as a supervisory controller to determine the optimal set-point for the PI controllers in th...
