Mathematical Modeling of a Generic Steam Turbine During Power Grid Dynamical Studies

摘要

Due to the significance of power systems dynamics studies, obtaining an accurate and consistent dynamical model for steam turbine-governor is a must. In this paper, dynamical modeling and parameter estimation of an industrial steam turbine governor are taken into consideration. The nominal output power of the turbine is 368 MW and dynamical tests are designed in four different operation point and two different modes of the system. During the tests, necessary signals are recorded by measuring devices and data acquisition systems. Before going through the modeling process the exact operation of the system should be examined. A precise dynamical model is proposed based on the operation of the system. In the next step, parameters of the suggested model are estimated using one of the most practical methods. The comparison between the response of the suggested model with the estimated parameters and response of the real system is made to show the accuracy of the proposed model.
