This paper presents a new power generating unit dynamic model that requires only one experiment for parameter identification. This model represents boiler pressure effects as a differentiating process with its subsequent identification through a new approach. In addition, a novel procedure is proposed for the model parameter correction in case that the identification test is not sufficiently informative. This dynamic model is developed in the vicinity of the steady-state operation mode. It can be used for load-frequency control purposes, boiler-turbine coordinated control tuning or its redesign, as well as a base for real-time simulators for dispatcher training. The modeling of 350MW power units of the Israel Electric is fulfilled through implementation of this model yielding sufficiently good results. A similar though less sophisticated approach was used by the authors  for the same purposes.
