Contemporary approach to determination of magnetic induction in wind generator air gap

Abstract

The  paper  describes  a  system  for  measuring  of magnetic induction on the wind generating unit. The manner of operation  and  the  application  of  the  Hall  effect  probe  are detailed.  Dynamic  electromagnetic  field  computing  results  are shown   through   application   of   MKE   on   the   synchronous generator  model  installed  in  a  windmill  unit  and  compared  to the  actual  metering  results.  Two  subsequent  magnetic  field calculations  on  the  modified  model  were  made  to  be  used  for analyses of the obtained results. Influences of air gap forms and saturation  to  time  dependence  of  magnetic  induction  at  a  point within the machine are explained.
