Popis:	New energy source is thriving in China. However, the fault characteristics of grids have been altered significantly with the penetration of new energy source increasing. In conventional researches, the fault features of wind farms were discussed briefly or simply overlooked. This paper began with the theoretical analysis of control system of full power inverted (FPI) sources and indicated that the response time of current control loop is 8.5 ms, while the steady state current of FPI source is controlled by reference values and set value of current limiter; the expressions of steady state current of FPI source were presented then. In addition, main factors affecting fault current, including different active power generation before fault, different fault locations and different fault types, were analyzed comprehensively and compared through simulation to gain a clear insight into the whole process of faults. The research is helpful to obtain a better understanding of new energy source.
