V venkatramana mar 10, 2003 #2 hi, in per. Usable reactive output that a generating unit is capable of delivering to the pjm interconnection and sustaining over the steady state operating range of the unit • planned. The capability curve or family of capability curves, show the mvar loading vs. Kvar (leading) a kvar (leading) kvar (lagging)) r.8) g s kw generator set operating range shown bounded by the blue line unity. The capability curve of generator is shown below. Implications of load angle & excitation on generator stability, significance of generator capability curve. The generator capability curves are used to model the dependence of the generator reactive power limits and the generator’s real power output. Generator rating is specified in terms of. Capability curve of an electrical generator describes the limits of the active (mw) and reactive power (mvar) that the generator can provide. The curve represents a boundary of all operating points in the mw/mvar plane; Gas temperature curve, determine the normalized mw increment. The generator load capability curve and generator operating capability include active power (mw), reactive power (mvar), and apparent power (mva). The generator operating point limits are stated and visualized in the form of the generator capability curve. Capability curve of generator defines the boundaries within which it can deliver reactive power continuously without overheating.
