摘要：

In the first part of this paper, a solar dynamic power system with a Stirling engine for space station application is described. Its unsteady behaviour is theoretically modelled and numerically simulated for four representative orbit configurations. The results are compared to that of a solar dynamic power module with a Brayton gas turbine. In the secund part, it is shown that the complex nonsteady behaviour of solar dynamic power modules with either the Brayton cycle or Stirling cycle can be analysed in a simplified way with sufficient accuracy for practical purposes on the basis of parametrizations and simple energy balances.
