Abstract:

International agreements have set high demands on the share of renewable energy in the total energy mix. Among the different renewable energy sources, significant investments are made in wind power. More and more wind turbines are being built and their number is rising dramatically. There are many different generator technologies, but this paper focuses on Doubly Fed Induction Generator (DFIG). DFIGs are the generators which are connected to the grid on both stator and rotor sides. The machine is controlled via converters connected between the rotor and the grid. The size of these converters determines the speed range of the DFIG. Wind farm connections to the grid must satisfy grid requirements set by Transmission System Operators (TSO). This means that the study on dynamic response of windfarms subjected to weak and strong disturbances and their Fault Ride Through (FRT) capabilities have become a critical issue. This is increasingly
important for induction generators, due to their growing size and number. Several computer softwares exist to carry out their dynamical simulations. This paper focuses on the use of DigSILENT Power Factory software to study the effect of crow bar resistance on the FRT capability of DFIG .
