Description

technical field [0001] The invention relates to the technical field of solar thermal power generation, in particular to a high-efficiency, compact and multi-functional dish-type concentrating power generation system. Background technique [0002] The increasingly severe environmental pollution prompts human beings to accelerate the development and utilization of new energy sources. Using solar power to generate electricity is an effective measure to develop new energy sources and protect the environment. Currently, solar power generation technologies include solar photovoltaic power generation and solar thermal power generation. [0003] At present, solar thermal power generation technologies mainly include tower type, trough type (including Fresnel type), and dish type. [0004] The basic principle of tower type and trough type photothermal power generation technology is that solar energy directly or indirectly heats water vapor through the concentrating heat collection sy...
