Abstract: Competition of short circuit current due to different types of fault that may occur in wind turbine generators grid is interest for many research projects. Under this principle, the emphasis is on the intelligent and fast analysis to prevent damage of equipment and reduce the expensive cost causes by these faults taking into account its nature for working in open areas far from cities. Determine the magnitude of short circuit current at any point of the bas-bar and node of the grid is significantly required to ensure the system reliability and prevent high stress on the equipment. In this research, 8 units of full-convertor variable speed induction generator type is considered by calculating short circuit current for all common of fault kinds. The fault current at each grid sections are computed by using intelligent method based on run length encoding strategy. The results show that the fault at generator terminal cause to huge current and it is very important to use sensitive protection system in order to prevent generator damage.
