ABSTRACT
Design-point and part-load characteristics of a gas turbinesolid oxide fuel cell hybrid micro generation system, of which
total power output is 30 kW, are investigated for its prospective
use in the small distributed energy systems.
A cycle analysis of
the hybrid system has been performed to obtain general strategies of highly efficient operation and control.
The method of analysis has been compared with previous results, of which power output values are set in the range from 287 to 519 kW.
Then, the
part-load performance of the 30 kW system has been evaluated.
Two typical operation modes, i.
e.
, constant and variable rotation
speed gas turbine operation are considered.
It is found that the
variable speed mode is more advant
Less
