Fault Ride-Through Capability of Variable-Speed Wind Generator Systems

9.1 Introduction

Wind energy generation has been noted as the most rapidly growing renewable energy technology. The increasing penetration level of wind energy can have a significant impact on the grid, especially under abnormal grid voltage conditions. Thus, wind farms can no longer be considered as a simple energy source. Nowadays, they should provide an operational ability similar to that of conventional power plants. A demanding requirement for wind farms is the fault ride-through (FRT) capability. According to this demand, the wind turbine (WT) is required to survive during grid faults. The ability of a wind turbine to survive for a short duration of voltage ...
