| Abstract: | Abstract A new type of control concept for the superconducting generator with electromagnetic shield coil instead of damper shells is proposed to avoid field current variations and improve the dynamic performance during transients This concept comprises both a field forcing system and a controller on the electromagnetic shield coil, which should be adjusted according to a specific control principle Comparisons are made, in the dynamic performance, when employing the field forcing alone and when the shield coil control is added to it. |
