Abstract: Vapour microturbines with permanent magnet synchronous generators are implemented in micropower plants for dispersed power generation systems. The dynamic model of such a microturbine set was developed and presented. The developed relations result from the generic equations. Experimental data for two different working medium were used for model verification. A microturbine set model was tested during the changes in the parameters of a working medium or an electrical load. Examples of a comparison between the experimental results and simulations are shown and discussed. The developed model ensures comparable accuracy as gas microturbine models found in the literature. In the case of vapour microturbine sets, in addition to accuracy, provides a larger area of operation. An operation during a start-up process was also analysed. Due to model simplifications, the accuracy decreases for a start-up operation from a cold state. The developed model can be a useful tool for some engineering applications or for studying the various operational aspects of vapour microturbines with permanent magnet synchronous generators.
