Abstract
The air gap flux density of the superconducting synchronous condenser is high. If the stator core uses a magnetic teeth structure, the teeth are easily overheating. For a 10Mvar superconducting synchronous condenser, Firstly, based on electromagnetic design and ventilation cooling calculation, the stator windings are determined to be water-cooled, and the radial ventilation channels are 10 grades. Then the stator core structure design without magnetic teeth is proposed, and the core slot and core end, and fastening structure are obtained. Two sets of clamping rings are used to realize the radial tightening of the core. Finally, a single tooth and single slot finite element model of the non-magnetic tooth was established, and the structural strength of the non-magnetic teeth was analyzed. The results show that the non-magnetic teeth meet the strength requirements of the rated condition and the strong excitation condition.
