Taking the capacity expanded geothermal and trough type solar power combined generation system as the research object, the temperature at outlet of the solar energy collection was estimated to obtain the optimum outlet temperature. Evaluation models for such indexes as generation efficiency, the increasing ration of power generation capacity and solar energy utilization fraction were set up to analyze the thermal performance of this system. By applying the Aspen Plus software, the geothermal-solar energy combine power generation system model for the geothermal power station in DPR of Korea was established. Moreover sensitivity analysis and optimization tool were used to calculate major parameters of this system, to obtain the best capacity expansion temperature, which is helpful to the system’s capacity expansion. The results show that, after the optimization, the generation power of the system was 4 044.5KW, the generation efficiency was 13.1% the hot water consumption was 94Kg/(KW•h), the steam consumption rate was 9.2Kg/(KW•h), the solar energy utilization percentage was 58.1% and the power generation increment ratio was 30.0%. Each performance index of the system enhanced significantly.
