【Abstract】 In order to provide a optimum scheme for the design of space solar dynamic power system, a assessing criterion of space solar dynamic power system is proposed according to the actual need of the space station ,then the mathematical and physical model for the energy balance and mass calculations is set up. Complex method is used to search for the optimal values of every parameters.. By the global optimization of space solar dynamic power system, the optimum value of parameters and the total launched weight were gained. The optimum total launched weight decreased by 11.1% than the average total launched weight. The results indicated that total launched weight is a effective assessing criterion which can combine both system mass and resistance area into a unified criterion.更多还原
