Steady State Performance

This paper describes the steady state performance analysis of a 3-shaft closed cycle helium turbine using nuclear heat source. The analysis is carried out using a computer program, which is specifically made for this cycle. The computer model was tested for various Turbine Entry Temperatures (TET) and absolute pressures. The analysis of the change was focused on the compressors, as these are relatively more critical than the rest of the equipments. The change in TET triggered changes in shaft speed, mass flow rate, power output, absolute pressure etc. Adjustable guide vanes were used to study the operation with constant surge margin. The closed cycle was tested for various absolute pressures and it was established that the efficiency will not be affected in using the inventory control for the load variation.

Steady State Performance

The dq-axis inductances are important for the voltage decoupling control, torque estimation and steady-state performance analysis of a PMSM machine. In this paper, a measurement method is proposed based on the dq-axis instantaneous flux linkages calculation. The rotor is locked by a positive d-axis current, and then a proper AC current is assigned respectively to the d and q-axis reference current in order to cover the various current ranges. The instantaneous flux linkages are calculated by the integration of dq-axis current and voltage offline. Finally, dq-axis inductances are computed by the integrated flux linkages divided by the dq-axis current.
