Abstract—With increasing global great concern over greenhouse gas emissions and their harmful effects on environment, huge number of wind turbines are recently connected to electrical grids. Nowadays, Egypt has continuous development of wind energy projects; it makes a great effort at Gulf of Suez area especially in Al-Zafarana district. This paper focuses on studying the dynamic performance of the 5th phase of Al-Zafarana wind farm, which is made of 100 Gamesa G52/850kW Doubly Fed Induction Generator (DFIG) machines, using Digsilent/PowerFactory simulation tool as an advanced simulation package. As DFIG is currently one of the most common types employed for Wind Energy Conversion System (WECS), the paper also implements a dynamic model for 850kW DFIG machine based WECS in Matlab/Simulink environment. A dual reference frame control strategy is applied here to improve the dynamic system performance during balanced and unbalanced grid voltage conditions.

Index Terms—Doubly Fed Induction Generator (DFIG), power generation control, unbalance grid voltage conditions, vector control, Wind Energy Conversion System (WECS)
