摘　　要：以某型10 MW闭式氦气布雷顿循环系统为研究对象,分析其分别采用容积控制法和旁通控制法调节系统负荷时的系统动态响应特性。研究表明:旁通控制法动态响应快但在部分负荷下系统效率降低,容积控制法动态响应慢但在部分负荷下系统仍能维持高效率。Based on the 10 MWth helium gas turbine closed brayton cycle,the dynamic characteristic performance of the different operating system under inventory control method and bypass control method is analyzed.The results show that with the bypass control method,the dynamic response of system is excellent,but the part-load efficiency is poor.With the inventory control method,the system efficiency can be high at some part-load conditions,but the transient response is slow.
