Szukana fraza: [Abstrakt = "In the paper, there is presented a mathematical model of a power system \(PS\) consisting of a generating unit \(with a synchronous generator\) connected by a high voltage power \(transmission\) line to a bus system. State and output equations of the generator are written in d, q, 0 coordinate system and with use of phase quantities \(especially useful in the analysis of asymmetrical states\) of the generator stator, bus system and power line. There was developed a compact mathematical description of the whole PS and there were calculated the waveforms of appropriate quantities in steady and transient states for selected asymmetrical loads. The calculations presented in the paper take into account the disturbance of the steady state in the form of a two\-phase short\-circuit in the transmission line. The influence of the excitation system and the governor of the generator as well as the effect of selected parameters of the generator model on the waveforms were investigated."]
