Abstract

This paper presents the results of analysis of steam turbine start-up using Thermal-FSI (Thermal-Fluid-Structure-Interaction). Reference and acceleration start simulations were carried out. Attention focused on a steam unit as they account for most electricity generation in Poland. Accelerated start-up is of interest as a possible method for reducing the adverse impact of renewable energy by controlling the injection of cooling steam, set against the backdrop of  increasing RES and their negative impact on the operation of steam units. The work is the result of research into the possibility of accelerating the start-up of a steam turbine.
