title = "Influence of Rotor Slot Wedge Material on Temperature Distribution of Dual-Excited Synchronous Condenser during Asynchronous Operation",
abstract = "A dual-excited synchronous condenser (DESC) with two sets of field windings can actively regulate rotor speed through AC excitation control to provide the inertial support for the power system. However, the inertial support capability of the DESC is limited by the losses and temperature rise during the asynchronous operation. In this paper, the inertial support mechanism of the DESC is analyzed and an electromagnetic-thermal coupling model of a 30-Mvar DESC is established based on the finite element method. The loss and temperature distributions of the DESC are calculated under the asynchronous operation with different rotor slips. The regions of the maximum loss density and maximum temperature are identified. The influence of slot wedge material on the stator and rotor loss density and temperature are studied. The variation of the temperature rise along with the slot wedge conductivity is revealed. Moreover, the influence of the temperature rise on the inertial support capability is studied. This paper can provide a theoretical basis for the inertial support capability of the DESC.",
