Development of a thermal power plant simulation tool based on object orientation

Abstract

This study presents a new dynamic simulation tool that facilitates plant and control system design of thermal power plants. In order to provide flexibility in building plant and control systems, object-oriented modelling techniques are used to model individual plant components, and each component object model is based on the verified first principles model. Further, simulation models can be easily built by connecting individual component object models, similar to the procedure adopted in an actual plant, by using a user-friendly graphical user interface. This tool enables the design engineer to build a simulation model, execute the simulation during the design process, test an actual plant control system, and adjust the control parameters. It is a useful design tool that accelerates and enhances the plant and control system design process.
