Simulation Pipeline Control Systems for Operator Training

Most pipeline simulations are primarily concerned with performance of the pipeline, and the modeler typically assumes an idealized model of the control systems. The modeler assumes that control devices operate instantaneously and perfectly. This assumption is sufficient for a wide range of engineering simulation tasks, but inadequate for simulations used to training pipeline operators. For training purposes it is important that the software provides a “virtual pipeline” that responds in the same manner as the real pipeline. The simulator should model the delays and interactions of the control system as well as the hydraulics of the pipeline. This paper describes how a generic control capability was added to an existing liquid simulation package to provide a more realistic training simulation for several applications including crude oil and multi-product pipelines. The paper will discuss the practical lessons learned from these simulations of the full control systems for pipeline training systems. The potential drawbacks of the method chosen will also be addressed.
