Abstract :
The paper presents research on underexcited turbogenerator operation capability. Measurements of basic electrical values for various loads have been carried out in case of 247 MVA turbogenerator. Synchronous reactance for various loads has been determined from measurements. Its influence on underexcited operation limits has been evaluated.
