Badania symulacyjne stanów przejściowych generatorów źródeł rozproszonych

The simulation investigations presented in the paper concern analysis of transient states of synchronous and asynchronous generators installed in distributed sources working in the medium voltage distribution network. The 15 kV network in which there were installed five distributed sources was an object of investigations. In order to stabilize the network operation, one source was equipped with a voltage and frequency regulator. In the framework of the investigations there was performed parameter optimization of the regulators with use of a simple genetic algorithm. There was carried out simulation analysis of separation of an island and transient short-circuit occurring during island mode operation. The uncertainty of generator mathematical model parameters was taken into account in investigations.
