Transient Voltage stability Enhancement of a grid connected wind energy system using SVC and STATCOM - A Comparison

Wind energy is one of the fastest growing renewable energy resources due to global warming. The high electrical power can be generated from an aggregation of multiple wind turbines as a wind farm or wind park. To interconnect it to the utility grid, control system must ensure high power quality and stability. Hence a better analysis of the wind farm is required as it contains induction generators which exhibit a different behaviors. This paper mainly deals with the study of transient stability of a grid connected DFIG wind farm when it has been integrated to a weak grid. A comparative analysis when it is supported with FACTS devices like SVC and STATCOM with fuzzy controller is studied. A single case of three phase fault is simulated and the results thus prove that the system can regain after disturbance with less recovery time when FACTS are implemented
