摘要:

本文针对热声发动机起振温度高、谐振管耗散的声功大和系统体积庞大等问题,提出了一种基于起动及发电运行的控制方法。通过对热声发电系统(TAEGS)基础知识的了解,并对热声发动机起振机理的分析,建立了热声发电系统的数学模型,研究了起动控制和发电控制的不同控制策略。在Matlab/Simulink环境下进行仿真,结果表明,基于起动及发电控制的热声发电系统起振时间短,热声电转换效率有所提高,为热声技术投入到生产实践中利用低品质热源提供了可行性保证。

Abstract:

Aim ing at the problems of high starting temperature, large acoustic power dissipation and huge volume of the thermoacoustic engine, a control method based on starting/generating bidirectional operation is proposed. Based on the understanding of the basic knowledge of thermoacoustic electric generation system(TAEGS) and the analysis of the thermoacoustic engine's starting mechanism, a mathematical model of thermoacoustic power generation system is established, and different control strategies for starting control and power generation control are studied. The simulation results in Matlab/Simulink environment show that the thermoacoustic power generation system based on start/generate bidirectional control has shorter starting time and higher thermal-acoustic-electricity (T-A-E) conversion efficiency, which provides a feasible guarantee for the thermoacoustic technology to be put into production practice in using low quality heat source.

Key words: Thermoacoustic electric generation system, tubular linear motor, thermal-acoustic-electricity (T-A-E) conversion efficiency
