Static voltage stability considering reactive power limit of salient synchronous generator and active power loss of exciter

International Journal of Electrical Power & Energy Systems
With increasing load, it is difficult to maintain power system static voltage stability (SVS). The existing SVS analysis based on the reactive power limit (RPL) of the non-salient synchronous generator (SG) and ignoring the exciter’s loss is inaccurate ...

Fault analysis and performance improvement of grid-connected doubly fed induction generator through an enhanced crowbar protection scheme. [PDF]

PLoS ONE
The main problem associated with a doubly fed induction generator (DFIG) during fault is large inrush currents induced in rotor winding, which has detrimental effects on the machine's AC excitation converter.

Reactive power limits in distributed generators from generic capability curves [PDF]

2014 IEEE PES General Meeting | Conference & Exposition, 2014
This paper presents a generic trapezoid-type capability curve for any distributed generation technology. This curve is used to estimate the machine reactive power limits in terms of the actual active power and terminal voltage. The proposed simplification was tested on synchronous machines, doubly fed induction generators and full power converter ...
