Small signal stability analysis of Jepirachi wind park

The actual development of wind energy in several countries around the world become it as the fastest growing power generation technology between green and clean technologies. Almost 50% of the installed wind turbines are induction generators. With the increase of induction instead of synchronous generators, electrical networks are experiencing different disturbances, which require permanent transient and small signal stability studies. This article presents an analysis of a small signal stability study in the first wind park installed in Colombia. In this analysis a software VORTEXOFT developed by the authors is used for aerodynamic purposes. A modal analysis and eigenvalues were done considering high level of wind power penetration. The results obtained indicate that the proposed method effectively identifies the stability operational point for a high level of wind power.
