Finally, a complete capability curve of doubly-fed induction generators for stator …
An induction generator connected to a capacitor system can generate sufficient reactive power to operate on its own. When the load current exceeds the capability of the generator to supply both magnetization reactive power and load power the generator will immediately cease to produce power. In other wording: the slip (s) from negative "slides" into zero (0) and this sets the induction machine "at the brink" to exit the generator mode and ready to enter the motor mode.Further th… WebCapability Curve of Synchronous Generator: Capability Curve of Synchronous Generator defines the bounds within which it can operate safely.
