With the increasing of wind generators and the scale of wind farm, it is urgent needed to establish a model which is proper and practical to short circuit current calculation. Firstly, this article analyzed the characteristics different types of wind generators’ short-circuit current and put forward different types model of wind generators shortcircuit current calculation. Secondly, considering the different types of wind generators and the influence of collecting system, this article established a wind farm shortcircuit current calculation model which is suitable for engineering application and based on the simulation requirements of 35kV and above high-voltage power grid. The simulation showed that the short-circuit current results used this model is similar to the results adopted detailed model, proving that using this article’s model can meet the engineering need and provide important reference value for power grid planning personnel in the grid short-circuit current calculation and the analysis of the restrictive measures. Keywords-wind farm; short-circuit; current calculation; practical model; simulation
