| Popis: | 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. |
