Abstract

Identification tests of dynamic and transient processes which occur in a power system are usually based on simulation. Structures of systems used for simulation testing are built from simplified models of power system components. Practically, in order to verify results obtained by simulation, they would have to be compared to data obtained in actual facilities. Research carried out at Kraków University of Technology and contained in the proposed paper shows that simplifications and assumptions used when constructing simulation models often cause a discrepancy between the simulation results and actual variability of the system state. This research was carried out using a five-node laboratory model of a power system built earlier. A full parameter identification process was carried out for this model, thus enabling construction of its computerised equivalent using the Mat lab software suite. The laboratory model which was used as a foundation for the simulation equivalent is a five-node system with a closed structure; it consists of four generation-load nodes and one load only node. Parameters of the components of the laboratory model, like power lines or generator outputs, have been selected in a process of power scaling. Experiments currently performed on the model are aimed at investigating dynamic processes occurring during and after a short-circuit, and at testing procedures for estimating power distribution at a static condition as well as fault containment procedures which are currently under development.
