Niesymetryczne obciążenie trójfazowego generatora synchronicznego
Języki publikacji
Abstrakty
The selection of a three phase synchronous generator most suitable to be used as a power supply for testing of single-phase and threephase power transformers is described in the paper. The emphasis is on the analysis of the armature winding connection and sizing of the damper winding due to unsymmetrical load of a generator in the temperature rise test of single-phase transformers realized by the short-circuit method. The generator’s output voltage waveforms in the case of unskewed and skewed stator slots are analyzed. The results indicate that delta-connected generator with skewed stator slots is the best solution.
W artykule opisano sposób doboru trójfazowego generator synchronicznego jako źródła zasilania dla testowanego transformatora jedno- i trójfazowego. Szczególny nacisk położono na uzwojenie twornika i rozmiary uzwojenia tłumiącego, ze względu na asymetrię obciążenia generatora przy wzroście temperatury w próbie zwarciowej transformatora jednofazowego. Wyniki analizy pokazują, że najlepszym rozwiązaniem jest generator ze skośnymi żłobkami stojana i uzwojeniach połączonych w trójkąt.
