英文摘要:

      The research object of this paper is the power generation system with new-style brayton cycle helium turbomachine which power is more than 100MW. The influences of inlet temperature of turbine, component efficiency, pressure ratio, inlet temperature of reactor core have been researched by the method of sensitivity analysis. And overall performance calculates, overall structural designs and experimental verification have been done in this paper. The results show that: output electric power is 119MW, generating efficiency is 47.54%, so this system has a better economic efficiency. Meanwhile, the maximal diameter is only 5.7m, the compactness is better than the traditional heat-exchange equipment. By the aforementioned work, it makes a massy basic for subsequent deep design of helium turbomachine power generation system.
