Comparing to the traditional generator, wind turbines have special short circuit current traits, which gives rise to many new problems in power system's protection control. Traditional protection methods can't meet the requirement of the safe operation of the power system. This paper firstly analyzes the double feed induction generator. Then for the typical wind farms, the effect of the collective...
Wind power gradually occupies important proportion in modern power grid. The influence of wind turbine generator (WTG) for protective relays has been studied in recent years, but a very few papers are presented to study relative influence to primary protection. This paper proposes a detailed analysis for the operating characteristic of transmission line primary protection in power network which are...
Doubly Fed Induction Generators (DFIG) becomes quite common employed in the wind farms. But the main disadvantage of DFIG is that it's very sensitive to grid disturbance, especially for the voltage dip. It could cause over voltage and over current in the rotor windings and consequently damaged the rotor side converter. In this paper, the author first made a theoretical analysis to the rotor current...
