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; it is typically drawn with the real power on the horizontal axis, and, for the synchronous … See more For a traditional synchronous generator the curve consists of multiple segments, each due to some physical constraint: • at the right part of the curve (close to the rated voltage), the generator is constrained by the … See more The variable renewable energy sources that use full power converters (solar photovoltaic (PV) generators, doubly-fed induction generators and full-converter wind generators, also known as "Type 3" and "Type 4" turbines ) to connect to the grid have reactive … See more • Kirby, Brendan J.; Hirst, Eric (1997).

WebJan 10, 2011 · Take a look at a generator reactive capability curve, they are helpful in visualizing the VAR capability as the PF changes. You are correct that for a motor the reactive power is absorbed, i.e. I lags V (lagging PF); a generator however delivers power to the system, and the generator action therefore supplies reactive power, I lags V, i.e ...
