  12. COOLING COST

  13. AC – APPLICTIONS • Superconductors have losses due to • Hysteresis • Coupling currents • Losses are dependent on (in magnetic fields above 50mT) • External magnetic field (~ B²) • Current (~ I²) • Frequency (~ f) • The Superconductor becomes a conductor with very low resistance • Factors are • Field B • Operating Current I • Frequency f • Combination of losses, operating temperature, overall efficiency and external factors (e.g. size requirement) determine economic feasibility

  14. 1.0 7.5 2.5 0.6 5.0 4.0 1.5 APPLICATIONS – Generator Advantages • No-loss excitation • Doubling of the magnetic field • Increased utilization of the winding • High degree of efficiency, low weight, compact construction Asynchronous generator Synchronous generator conventional HTS generator Source: Siemens AG Diameter [m] Weight [t] Losses [%] Comparison of conventional and HTS-excited 1500 kW electric generators
