Dynamic Simulation and Optimization of Start-up Processes in Combined Cycle Power Plants

Abstract

This paper treats the development of a dynamic simulation model and its application to the optimization of a start-up process for a combined cycle power plant. Generally, the plant system design is complicated, and the control design is difficult to establish without dynamic simulation. The comparison of the simulation results and the plant data is reported. The obtained results demonstrate that the simulation is reliable to evaluate the plant dynamic phenomenon and available to predict the operational processes. However, not only an analytical method but also the development of a design method is important to determine the optimal operational procedure. In this paper, the dynamic simulation and the nonlinear programming are combined, and it proposes the design method that optimizes the operational parameters.
