“…The distribution of the stray magnetic field of the winding, current, and inductance of the parallel branch are calculated; the test is not carried out but it is important [18]. The magnetic field distribution of the dry-type smoothing reactor is measured in [19,20], but its measurement range is limited to one side of the pole bus-level smoothing reactor, and the influence of the geomagnetic field and full-load operation on the measurement results is not considered.…”

With the rapid development of ultra-high-voltage direct current (UHVDC) transmission, air core smoothing reactors have become the main source of electromagnetic contamination in converter substations. The actual magnetic field distribution was obtained by measuring the magnetic induction intensity of the polar busbar smoothing reactor under full load operation condition of the Jiaodong ±660 kV converter substation. A method combined with the measured data to eliminate the influence of the geomagnetic field is proposed. The magnetic field distribution model of the smoothing reactor is established and the rationality and validity of the model for magnetic field distribution is verified. Some magnetic shielding measures are proposed and their effectiveness is verified by simulation and small-scale experiments.
