中文摘要：
碟式太阳能行波热声发电是近年来兴起的新型热发电技术，具有可靠性好、潜在效率高、分布灵活等优点。本文介绍了正在研制的一套1kW碟式太阳能行波热声发电系统。该系统利用碟式集热器收集太阳辐射热量，通过高温热管将热量传输到发动机热端，再采用行波热声发电机进行热一电转换。初步调试采用高频加热模拟太阳能，以3．5MPa氦气为工质、加热温度为751℃和798℃时分别实现了116W和255W的电功输出。实验验证了系统的可行性。目前系统的安装调试仍在进行中，相关的实验结果将在后续的文章中进行报道。
英文摘要：
Solar dish traveling-wave thermoacoustic electricity generator, which has advantages on high reliability, high intrinsic efficiency and high flexibility, has been developed as a novel thermoelectricity device in recent years. In this paper, a 1kW solar-powered traveling-wave thermoacoustic electricity generation system has been built. In this system, a dish solar collector is used to collect the solar irradiation, a high-temperature heat pipe is used to transfer the heat to the hot end of the traveling-wave thermoacoustic heat engine and the generator is used to convert the heat to the electricity. In the preliminary experiments, a high-frequency induction heating machine is used to simulate the sunlight and electrical powers of 116 W and 255 W are achieved at 751℃ and 798℃ heating temperature with 3.5 MPa pressurized helium. The results show the feasibility of the whole system. Nowadays, system improvements are under way and more results will be reported in the future.
