In MW-sized wind turbines, the most widely-used generator is the wound rotor induction
machine, with a partially-rated voltage source converter connected to the rotor. This …

In the case of adjustable drives systems with an induction motor (IM), a harmonic regime is
manifested, whose knowledge and analysis are always necessary. However, most studies …

Operation and maintenance costs of wind power plants represent a significant share of the
total expenditure of a wind farm project. It is therefore vital to optimize maintenance activities …

In some power systems, voltage subharmonics and interharmonics of significant value may
occur. They exert a harmful effect on various energy receivers, including induction motors …

This paper presents the results of experimental evaluation of interharmonics produced by
PV inverters (PVInv) for a range of different operating conditions. First, intrinsic interharmonic …

The interactions between randomly fluctuating power outputs from photovoltaic (PV) at the
DC side and background voltage distortions at the AC side could generate interharmonics in …

In power systems, various power quality disturbances are present, including voltage
deviation, voltage unbalance, and voltage waveform distortions. Voltage waveform …

In this study, a wound rotor induction machine, as the core of a doubly‐fed induction
generator (DFIG) system, is modelled using the magnetic equivalent circuit approach. The …

This article presents a novel study of stator electrical faults detection using the wide-band
spectral signatures in the controller signals of doubly fed induction generators (DFIGs). The …

This paper presents a novel study of the wide-band spectral signatures in the controller
signals of doubly fed induction generators (DFIGs) for the identification of rotor electrical …
