Nowadays, various programs for optimization and simulation of power systems are used. Mathematical model based on particular system element characteristics is a core of this type of programs. How accurate the modelling is depends on the accuracy of implemented characteristics. In the course of time, characteristics are subject to change (ageing process). Continuous correction of characteristics must be done to keep them up to date. Till now, characteristics have been built based on thermal measurements, performed, by special companies and could not be corrected in the on-line mode. Today, most power plants are equipped with distributed control system (DCS). These systems collect information for controlling, perform the control and archive the results of measurements. A large number of values are collected even duringshort system working time. These data can be easily used in different types of calculations. One of them is identification of characteristics. This type of data allows correcting characteristics in on-line mode.
