Harmonic aspects of wind power integration [PDF]
Journal of Modern Power Systems and Clean Energy, 2013 This paper discusses a number of ways in which wind power installations can impact the harmonic levels in the power system. Wind turbines are an additional source of harmonic emission, especially when it concerns “non-characteristic harmonics.” Parallel resonances can amplify the emission from individual turbines.

Harmonic measures for distributions with finite support on the mapping class group are singular [PDF]
, 2014 Kaimanovich and Masur showed that a random walk on the mapping class group for an initial distribution whose support generates a nonelementary subgroup when projected into Teichmüller space converges almost surely to a point in the space PMF of ...

Analysis of AC winding loss of permanent magnet synchronous traction motor with high power
机车电传动, 2022 In a multiple-pole and high-power PMSTM with high fundamental frequency, the harmonic frequency of the internal magnetic field increases accordingly. The harmonic magnetic field will induce eddy current in the winding, resulting in high-frequency eddy ...
