Analysis and Simulation of Transient Behavior of the Generating Unit with Reheat Steam Turbine Against Load Changes

The main purpose of this paper is to investigate the dynamic behavior of the steam generating unit in exchange for load changes in the system. The equations of the production unit equipped with preheater are determined using the linear model of the system in the state space. Changes in mechanical power and speed deviations of the generating unit are shown in exchange for changes in load demand. The transient behavior of the turbine steam valve is also investigated. The eigenvalues ​​of the system matrix are calculated in two modes without preheater and equipped with preheater and the response attenuation coefficient is investigated and the simulation results are analyzed using them. Preheater parameters (heat reduction) have no effect on the steady state response but on the transient response of the system.
