Doubly-fed induction generator is widely used in wind turbine conversion systems. Several research works are being made to efficiently approve existing condition monitoring and fault detection techniques for these systems. The condition monitoring of these systems becomes more and more important, the main obstacle in this task is the lack of an accurate analytical model to describe a faulty DFI...

Variable speed generator systems (VSGs) are at work in the now 600 GW installed wind power plants (parks). Also, they used as vehicular and on ground stand-alone generators. VSGs imply full kVA rating PWM converters permanent magnet (PM) or electrically excited synchronous cage rotor inductance But, to reduce cost absence of PMs a reasonable initial (weight) efficiency, fractional converter dou...

Wind power generation systems influence power quality in a specific way making important the need for detailed and accurate evaluation of disturbances caused by wind generators. Wind power system can cause suband interharmonic components to appear in the spectrum of voltages and currents.
