| Based on concentrating solar cogeneration system, this paper presents an analysis of the integration mechanism in photovoltaic/thermal (PV/T) cogeneration system with compound parabolic concentrator. Efforts is made in studying ways ofsystem structure,optimizationof system’s thermodynamic efficiency and photoelectric performance. Power-efficient calculation model and heat balance equations,which were based on heat transfer network diagram analysis, have been built. And thecalculationof working fluid flow rate and heat energy supply system efficiency is analyzed. At the same time monitoring and control systems which can be applied to the concentrating solar cogeneration systems was also be set up. A good user experience interface and controlalgorithms were developed to operate the concentrating solar cogeneration system whit real-time monitoring and automatic control. Studies show that the system has a high solar energy utilization efficiency and good operation stability.This paper can provide theoretical basisforsolar energy utilization, and technical support in industrial development of CPC-PV/T systems. |
