This paper presents methodology of identification of dynamic models of steam turbine, governor, boiler and its regulators required for investigation and dynamics analysis of stability of power systems. According to the methodology, structure and parameters of dynamic model of generating units are estimated taking into consideration operating mode of turbine and boiler. Measured and simulated regime parameters' curves are presented. Correlation factors of measured and calculated regime parameters for evaluation of identification accuracy are estimated. Expressions for recalculation of model parameters to one apparent generating unit’s power are presented, too.
