The system comprises a solar power light condensing device, a thermoacoustic motor, a sound wave conversion device, a piezoelectric power generation device, an electrical energy conversion device, and an energy storing device. The system and the method effectively solve the problems that the structure is complex, the size is large, the operating frequency is low, high-power power generation can not be conducted, and the advantage that the thermoacoustic motor produces high frequency stress wave easily can not be effectively played existed in an electrolyte-magnetic field coupled power generation system and a linear oscillatory power generation system adopted by a conventional solar power thermoacoustic piezoelectric power generation system. Therefore, the solar power thermoacoustic piezoelectric power generation system provided by the invention has simple structure, smaller size, convenience in mounting, stable and reliable operation, and high power generation efficiency of the overall system; meanwhile the scale of the solar power thermoacoustic piezoelectric power generation system can be set according to actual requirements, the manufacturing is flexible, the manufacturing period of the overall system is short, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to solar thermal power generation technology, in particular to a solar thermoacoustic piezoelectric power generation system and a power generation method thereof. Background technique [0002] At present, steam engines and Stirling external combustion engines are generally used in solar thermal power generation systems to generate electricity. The existing steam engine power generation systems have poor utilization and power generation efficiency, and the heat utilization rate is low. It can only be improved by building a large enough system. The utilization rate of solar energy leads to high construction cost and long period; and in the existing Stirling external combustion engine power generation system, there are many mechanical moving parts, which makes the manufacturing and installation process of the whole system complicated and costly. The reliability and practicability of o...
