Offshore wind farm harmonic resonance analysis — Part I: Converter harmonic model

2017 IEEE Manchester PowerTech, 2017
Offshore wind power technology has matured significantly and now directly competes with conventional and onshore wind power generation. Thanks to continuous technological developments and significant cost reduction, offshore wind power is closing the gap with the onshore wind power about the levelized cost of electricity; however the technology ...

Optimization design of stator harmonic windings in brushless synchronous machine excited with double-harmonic-windings

2017 International Energy and Sustainability Conference (IESC), 2017
Harmonic brushless excitation synchronous machine does not rely on permanent magnetic material, which also can be excited without brush and slip rings. The air-gap magnetic fields are easy to be adjusted. However, the tooth harmonics in 12-slots machine are relatively big.

Harmonic modelling of offshore wind farms

IEEE PES General Meeting, 2010
The combination of extensive cable networks and wind turbine converters has been identified as a potential cause of resonances. A modelling approach for a doubly fed induction generator and a full power converter fed generator for harmonic penetration studies is developed and discussed.

Measurement of wind farm harmonic emissions

2008 IEEE Power Electronics Specialists Conference, 2008
In this paper, harmonic voltage and current measurements performed at the Point of Common Coupling of an existing wind farm comprising five variable speed wind turbines are analyzed and their most important characteristics are presented. Important issues under consideration are the variation of harmonic currents with the wind farm output power, the ...
