Design and Analysis of a Novel Hybrid Solar/Gas Dish Stirling System (HS/GDSS)

摘要

In this paper, a 20kW design capacity solar parabolic dish concentrator hybrid solar/gas dish Stirling system (HS/GDSS) is proposed. To ensure a steady operation of an electricity power plant, HS/GDSS uses gas as complement when solar radiation is weak. Thermodynamic models were made to conduct design of system parameters. After detail characteristics were chosen, analysis was carried out to evaluate this system. The results show that within design condition, overall efficiency of the system is 27.58% at daytime and 33.94% at night, which has advantages over single-energy solar dish Stirling electricity power plant.
