Abstract







There was analysed the operation of a factory power network working in island mode and cooperating with the Polish National Power System (PNPS) in selected transient states. It was assumed that two generating units: one with an asynchronous generator, and the second with a synchronous generator, were installed in the network. The behaviour of the generating units was analysed in the following transients: transition of the factory network from cooperation with the PNPS to island mode operation and shutdown of the asynchronous unit. The analysis took into account the uncertainty of the parameters of selected models of network elements. In the paper, there is described the problem of modelling the scatter of parameters of the models of electrical systems. It consists in determining the envelopes (limit bands) for a family of waveforms of the analysed signals. These envelopes were determined using multiple simulations when changing the network model parameters in an appropriate manner. There is shown the possibility of improving the angular stability of the analysed network by the use of stabilising systems with an appropriate structure and optimised parameters. It is proposed to introduce these stabilising systems to the turbine governor and the synchronous generator excitation system. Parameters of the stabilising systems were optimised by minimising the defined quality factor of electromechanical control waveforms in the selected transient state. A genetic algorithm was used to minimise this quality factor.
