The detection of VFC and STATCOM faults in Doubly Fed Induction Generator

The wind power has the most rapid growth in comparison with other renewable energies. During last decade wind energy has became an important part of the electricity production throughout the world. As the amount of wind energy increase, the reliability of the wind turbines becomes crucial. A low reliability would result in an unstable energy source with poor economical performance. Monitoring the condition of vital components is a key element to keep a high reliability. Condition monitoring of Doubly Fed Induction Generators (DFIG) is growing in importance for wind turbines. This paper investigates the effect of VFC (Variable Frequency Converter) and STATCOM Faults on wind turbine equipped with DFIG operation in order to condition monitoring of wind turbine. Consequently, a proposed method is used to detecting these faults means of harmonic components analyzing of DFIG rotor current. The simulation has been done with PSCAD/EMTDC software.
