Criterion for the electrical resonance stability of offshore wind power plants connected through HVDC links
(2017-11-01)
Article
Accés obertElectrical resonances may compromise the stability of HVDC-connected offshore wind power plants (OWPPs). In particular, an offshore HVDC converter can reduce the damping of an OWPP at low-frequency series resonances, leading ... -
Load identification of different Halbach-array topologies on permanent magnet synchronous generators using the coupled field-circuit FE methodology
(2018-01-01)
Article
Accés obertIn this paper, the influence of gap consideration on load identification under various Halbach-array-based topologies (HABOs) is investigated while the system is on-duty. The load characteristics of a radial flux generator ...
