Abstract

In the development of a high temperature superconducting synchronous generator it is important to analyse the magnetic saturation o the machine so that its internal state during load operation prior to the disturbance is accurately predicted. Furthermore, the use of a superconducting field winding makes the machine more vulnerable to system instability. A modest increase in the field current may cause large loss densities in the winding, leading to thermal runaway. This would require the machine to be shut down while the winding temperature returned to normal, which would compromise the reliability of the machine. In this paper a method, employing finite element analysis, is established to calculate the saturated reactances of synchronous machines under steady state operation.
