Construction of turbogenerator capability curve for high reactive power region by Potir reactance
University of Belgrade, Electrical Engineering Institute 'Nikola Tesla'


Calculation and analysis potier reactance dependence in high reactive power region (QG ≥ QG,N). Important conclusion is that corresponding potier reactance values practically equally that in rated regime. It is enabled that excitation current calculations and construction corresponding generator capability curves (P-Q curve) performed by potier reactance rated values (xp≈xpN) and the open-circuit saturation curve. From reactive load test are dermined xp,N values. Greatest difference between P-Q curves, obtained from designers and by presented procedure, is result change of generator voltage in relation to rated. It is shown that P-q curve calculation in high reactive power region by Potir method is simple and sufficiently accurate.
