Abstract


Modern society, rapid economic development and growing human demand for conventional energy sources , from the point of view of sustainable development , research , development and utilization of new energy is imperative . Thermoacoustic power generation technology is designed to take advantage of solar energy, industrial waste heat , automobile exhaust and chemical fuel combustion and produce low - quality energy to work , because this technique has the advantage of efficient , environmentally friendly , low emission , it has become one of the fields of the Electric Power Research Xiang cutting-edge technology . Thermoacoustic power principle is : first low-quality thermal energy acoustic oscillation is converted into kinetic energy , with such a kinetic energy to drive the generator power . The thermoacoustic power its most important feature of the simple mechanical construction the thermoacoustic generator part of the mechanical structure of the traditional turbine movement to get rid of , and increase system reliability and environmental advantages , and can be made without intermediate moving parts hair system , therefore , the thermoacoustic power generation system has an important application prospect , theoretical and practical significance . The birth of the permanent magnetic materials , permanent magnet linear generator performance has been greatly improved . In this thesis, a novel structure of permanent magnet linear generator design it from either the structure or process for the characteristics of the thermoacoustic power generation system . This paper the special structure of the novel linear generator used in thermoacoustic power generation , sub - load power generation system as a thermoacoustic vibration free piston type permanent magnet linear generator , a cascade generation mode , so that power generation can range from very small to large. Established throughout the thermoacoustic power generation system dynamic equations using matlab M function is programmed , through simulation curve to analyze the dynamic characteristics of the thermoacoustic system , the effects of the resonant frequency , load resistance and piston diameter generator performance . Finally , this paper describes the post-processing of the system 's energy program , through the control circuit , the completion of the electrical energy storage .
