Resumen:
There is currently a strong trend in theworld toward the use of power generation from renewableresources. This poses new challenges with respect to the modelingof electrical generators connected to power electronics devices,such as Doubly Fed Induction Generators (DFIGs). Theinitialization of DFIG models to be used for transient studies is critical. This article presents an approach to the modeling of DFIG in the ATP calculation environment using the Universal Machine type 4 model, which focuses especially on the automatic model initialization. A methodology for initializing the generator for a desired operating point at subsynchronous speed is proposed, which can be used to initialize a detailed wind DFIG. Acase study is presented to validate the methodology. The results show that the initial operating conditions of the DFIG can be calculated very accurately using this approach.
