Abstract

The invention provides a hybrid system modeling and simulating method aiming at a process industry tank field on the basis of finite state machine technology. The method includes that tank field equipment is mapped into a finite state, various tank field operations are simulated to analyze dynamic behaviors of a system itself, influence of various operations is evaluated to guarantee reasonability of various production operations, and a reliable basis is provided for standardizing operation behaviors of actual operating personnel.

Description

technical field [0001] The invention belongs to the field of process analysis and simulation modeling of tank farms in the petrochemical industry, and in particular relates to a hybrid system modeling and simulation method for process industry tank farms. Background technique [0002] At present, process industry simulations mostly focus on preparing simulations for equipment and process flows, and usually use algebraic equations or differential equations to describe mass transfer, energy transfer, momentum transfer, reaction kinetics, and physical and chemical properties in the petrochemical production process . In order to quantitatively reveal the steady state or dynamic changes of the system. For example, the relatively mature dynamic simulation commercial software HYSYS. Unlike other process industry simulations, oil tank farm simulation not only includes various dynamic continuous production behaviors, but also includes various discrete process operations. Such tank...
