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 ...

Self-Excitation and Harmonics in Wind Power Generation

Journal of Solar Energy Engineering, 2005
Traditional wind turbines are commonly equipped with induction generators because they are inexpensive, rugged, and require very little maintenance. Unfortunately, induction generators require reactive power from the grid to operate; capacitor compensation is often used.

Aggregation and amplification of wind-turbine harmonic emission in a wind park

2015 IEEE Power & Energy Society General Meeting, 2015
This paper presents measurements of harmonic and interharmonic current (with 5-Hz frequency resolution) in the complex plane. The complex currents are spread around a center point. For interharmonics, this center corresponds to the origin of the complex plane. For integer harmonics, this center is offset from the origin.

Harmonic analysis for fixed-speed wind turbines

2013 IEEE Power & Energy Society General Meeting, 2013
This paper presents harmonic analysis of a fixed-speed wind turbine in a utility distribution system. It shows a condition of how the wind turbine may be involved in harmonic resonance through its power factor correction capacitors. In addition the effect of wind speed on the resonant frequency is also considered.

Review of harmonics in offshore wind farms

2013 48th International Universities' Power Engineering Conference (UPEC), 2013
This paper presents a review of harmonics in offshore wind farm systems. The aim is to gather information of mathematical models for harmonic analysis in wind farms and algorithms to configure offshore network interconnections. A thorough literature review is presented that may help to develop a solution in MatLab or LabView for harmonic analysis in ...

Harmonics in Offshore Wind Power Plants

2016
This book reports on cutting-edge findings regarding harmonic stability assessment for offshore wind power plants (OWPPs). It presents a timely investigation of the harmonic stability interaction between OWPPs on the one hand, and associated control systems in the wind turbines and other power electronic devices in the transmission system on the other.

Harmonic current characteristic analysis for wind turbines

2013 IEEE 10th International Conference on Power Electronics and Drive Systems (PEDS), 2013
This paper analyzes the harmonic current characteristic of wind turbines. Field measurement, data sorting, and analysis are conducted for wind turbine. Most wind turbines at present use a power converter and are equipped with harmonic filters, the control results of these equipments will become highly stochastic as wind speed changes.
