Example Embodiment

[0022] The following describes the implementation of the present invention in detail with reference to the drawings and embodiments.

[0023] Such as figure 1 As shown, the two-circuit solar thermal power generation system of the present invention includes a first-circuit solar heat collection subsystem and a second-circuit steam power generation subsystem. The solar heat collection subsystem uses the solar heat collection field 3 to focus sunlight to heat the working fluid of the primary circuit, and the obtained high-temperature working fluid is stored in the high-temperature storage tank 4 for the secondary circuit; the secondary circuit steam power generation subsystem uses the high-temperature storage tank The primary circuit working fluid in 4 heats water and steam to produce steam of various pressures and temperatures, which are incorporated into the steam turbine 15 to drive the steam turbine generator set to generate electricity. The primary circuit working fluid after c...

Abstract

A two-loop type solar thermal power generation system comprises a first-loop solar heat collecting subsystem and a second-loop steam power generation subsystem. The first-loop solar heat collecting subsystem obtains high-temperature working media by the way of heating low-temperature working media through solar energy and stores the high-temperature working media. The second-loop steam power generation subsystem is used for generating various kinds of steam with different pressures and temperatures by the way of heating water and steam by the high-temperature working media to drive a steam turbine generator unit to generate power. The heated high-temperature working media lowers to be low-temperature working media and are conveyed back to the first-loop solar heat collecting subsystem to be continuously heated. The solar heat collecting subsystem and the steam power generation subsystem operate independently and do not affect each other. The two-loop solar thermal power generation system can be used for removing system fluctuations caused by uncontrollable factors of solar radiation strength variation, cloud shielding and the like, adjusting of the power generation power of the steam turbine generator unit and continuous and stable power generation can be achieved, and the power generation efficiency of the solar thermal power generation system is improved.

Description

technical field [0001] The invention belongs to the technical field of solar thermal power generation, in particular to a two-circuit solar thermal power generation system. Background technique [0002] Solar energy is widely distributed and has huge reserves. It is a clean and renewable energy with broad application prospects. At present, there are two main forms of solar power generation technology: photovoltaic power generation and solar thermal power generation. Photovoltaic power generation uses the photovoltaic effect of semiconductor devices to directly convert solar energy into electrical energy. It has the advantages of high reliability and convenient installation and maintenance. However, the cost of photovoltaic power generation is high and the efficiency of photoelectric conversion is not high. Solar thermal power generation uses a concentrator to gather solar energy, which is absorbed by an absorber and converted into heat energy to generate high-temperature st...
