Tóm tắt

A systems analysis was conducted to evaluate the effects of hybrid scale on overall performance. The benchmark was the highly efficient turbine in a 550 MW hybrid power system. This was compared to a nano-hybrid system of 20 kW with reduced isentropic efficiencies for the smaller scale turbomachinery. Electrical efficiency was remarkably high even with the small inefficient turbomachinery. The SOFC share of the power was a low 68% for a fixed SOFC fuel utilization (Uf) of 0.7.
