Multiphase winding homologous series synthesis and harmonic analysis
Electrical engineering & Electromechanics, 2014 Multiphase windings are shown to form three types of homology. A bipolar winding homology formation algorithm is developed. Change in electromagnetic properties of the windings forming a homologous series proves to uniquely comply with the law of the ...

Harmonics in a wind power plant [PDF]
2015 IEEE Power & Energy Society General Meeting, 2015 Wind power generation has been growing at a very fast pace for the past decade, and its influence and impact on the electric power grid is significant. As in a conventional power plant, a wind power plant (WPP) must ensure that the quality of the power being delivered to the grid is excellent.

Harmonic Measure and Winding of Conformally Invariant Curves [PDF]
Physical Review Letters, 2002 The exact joint multifractal distribution for the scaling and winding of the electrostatic potential lines near any conformally invariant scaling curve is derived in two dimensions. Its spectrum f(alpha,lambda) gives the Hausdorff dimension of the points where the potential scales with distance $r$ as $H \sim r^α$ while the curve logarithmically ...

Harmonic Current Predictors for Wind Turbines [PDF]
Energies, 2013 The harmonic impact caused by wind turbines should be carefully investigated before wind turbines are interconnected. However, the harmonic currents of wind turbines are not easily predicted due to the variations of wind speed. If the harmonic current outputs can be predicted accurately, the harmonic impact of wind turbines and wind farms for power ...

Assessing Time-Varying Harmonic Interactions in a Wind Park [PDF]
IEEE Access, 2021 The harmonic interaction mechanism in a wind park is examined in this paper. The paper investigates the feasibility of a solution to the yet challenging harmonic contribution estimation from multiple sources in a wind park with limited available information, via an extension of a simple modeling approach as well as from detailed analysis of field ...
