A new power generating units dynamic model

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 and can be used for load-frequency control tuning or its redesign, for Automatic Generation Control purposes, as well as a base for real-time simulators for dispatcher training. The modeling of 575MW power units of the IEC (Israel) is fulfilled through implementation of this model yielding sufficiently good results.
