The nonsteady operational behavior of single- and two-shaft closed-cycle gas turbines is investigated on the basis of two reference plants. The behavior in case of a full-load release and after emergency shutdown was calculated. It is proved that these disturbances of operation can be mastered in two-shaft plants as well as in single-shaft plants. Furthermore, the stresses caused by dynamic changes in the circuit and to be considered in designing a closed-cycle gas turbine were investigated.
