Study on Real-Time Operating Simulation of a One-Dimensional Incompressible Single-Phase Fluid Flow Network

The plant operation simulation system is a device that analyzes the operating dynamics of the plant and supports the operator to conduct operational training in the same environment as the actual situation of the plant. With the rapid development of computer science and technology, various types of plant operation simulation systems have been developed worldwide, used for control system design, operator training, and development of operating procedures, and recently, advanced scientific and technological achievements have been introduced to further improve the performance of process simulators and expand their application range. This paper presents a methodology for real-time modeling of the dynamics of a single-phase fluid flow network, which is a large part of the plant thermal system configuration, and, this basis, aims to perform operational simulations of auxiliary systems of the plant.
